Presentation 1
Bones are living tissue composed of cells, proteins, minerals, and vitamins. They provide structure and protection for the body, serve as an environment for bone marrow, and store minerals like calcium. There are two types of bone tissue - compact bone forming the hard outer layer, and spongy bone on the inside. Bones are made through the actions of bone cells including osteoblasts which build bone, osteoclasts which break it down, and osteocytes which maintain it. The human body contains 206 bones divided between the axial skeleton including the skull, spine, ribs, and sternum, and the appendicular skeleton making up the upper and lower limbs.
Anatomy unit 5 skeletal and muscular systems bone types and composition
This document discusses the anatomy and composition of bones. It notes that bones provide support, protection, movement, mineral and growth factor storage, and blood cell formation. There are four types of bones: long bones, which are longer than wide and provide structure and support; short bones, which are cube-shaped and allow for movement; flat bones, which are thin and curved to protect soft tissues; and irregular bones, which have complicated shapes. Bones are made up of an outer layer of compact bone and an inner layer of spongy bone. The chemical composition includes both organic components like cells and osteoid, and inorganic mineral salts.
Anatomy Unit 4 Notes: Bone Injury
The document describes 10 different types of bone injuries: comminuted fractures which break bone into 3 or more pieces; spiral fractures which result from twisting forces; depressed fractures where part of the bone is pressed inward; transverse fractures which break straight through the bone; oblique fractures which break on a diagonal; open fractures which break the skin; compression fractures which crush the bone; epiphyseal fractures where the epiphysis separates from the diaphysis; greenstick fractures which break incompletely on one side like a twig; and provides brief descriptions of the causes and characteristics of each type.
APU4.2 Skeleton System (Bone Structure)
There are two types of bone tissue: compact bone and spongy bone. Compact bone is dense and forms the outer protective layer, while spongy bone is less dense and found in low-stress areas. Bones are composed of osteocytes, osteoblasts, osteoclasts, and osteogenic cells which build, maintain, and remodel the bone tissue. Typical bone structure includes a diaphysis shaft surrounded by compact bone, epiphyses at the ends composed of inner spongy bone and outer compact bone, and metaphyses of cartilage between.
section 1, chapter 7: skeletal system
The skeletal system provides structure, protection, movement, mineral storage, and blood cell production. Bones are composed of collagen fibers, hydroxyapatite, and cells like osteocytes, osteoblasts, and osteoclasts. There are different types of bones classified by shape like long, short, flat, and irregular bones. Long bones have a diaphysis, epiphyses, and medullary cavity. Compact bone lines the diaphysis and is made of osteons, while spongy bone fills the epiphyses. Bones form through intramembranous or endochondral ossification, where cartilage is replaced by bone. Growth occurs at epiphyseal plates until skeletal maturity.

Chapter Seven is the chapter that focuses on bone tissue. The anatomy, orgina and physiology of human bone tissue and how it is developed.
Skeletal System Outline
The skeletal system provides structure, movement, protection, and storage. It is composed of bones, cartilage, tendons, and ligaments. Bones come in four basic shapes and have two types of bone tissue: compact and spongy. The skeletal system is divided into the axial skeleton which includes the skull, vertebral column, and rib cage, and the appendicular skeleton which includes the shoulders, hips, and limbs. Joints like ball-and-socket, hinge, pivot, and gliding, allow movement. Common skeletal problems include osteoporosis, arthritis, scoliosis, and bone cancers.
Lesson 1 skeletal system
This document provides an overview of lesson 1 on the skeletal system. It discusses the structure and functions of the skeletal system, including:
- The axial and appendicular skeleton and their components
- The five main functions of the skeleton: protection, support, movement, blood production, and mineral storage
- Bone growth and how cartilage is changed to bone through ossification
- Key bones such as the femur, humerus, ribs, and vertebrae that are involved in blood cell production
Muskloskeletal physiology mbbs 4 batch [6]
Bone tissue is a complex living tissue that is continuously remodeling itself through the breakdown of old bone and formation of new bone. It consists of several cell types within an extracellular matrix of collagen fibers and mineral salts. Bone provides structural support to the body, protects internal organs, assists in movement, stores minerals, produces blood cells, and stores fats. The continuous remodeling of bone tissue through the actions of osteoblasts and osteoclasts allows bones to maintain their strength and repair damage.
Skeleton, Joints And Bones
The skeleton provides protection of delicate organs like the brain, support for the body's soft tissues allowing it to stand up, and allows for movement as muscles can attach to bones via tendons. There are different types of joints like ball-and-socket, hinge, and fixed joints that enable different ranges of motion. Joints are composed of bones, cartilage, synovial fluid, tendons, ligaments and in some cases menisci, working together to facilitate and limit movement of the body.
APU4.5 Skeleton System (Articulations & Movement)
Articulations are where bones meet, and are classified based on their structure and function. The three main types of joints are fibrous, cartilaginous, and synovial joints. Synovial joints are the most common and include ball-and-socket joints like the shoulder, hinge joints like the elbow, and gliding joints like those between vertebrae. Joints allow various movements like flexion, extension, and rotation through the interaction of bones, ligaments, muscles, and other tissues.
LT4.1 Introduction to the Skeletal System
The skeletal system has several key functions:
1. It provides structure and support for the body, protects vital organs, and allows for movement.
2. Bones act as a reservoir for minerals and as sites for blood cell formation in the bone marrow.
3. The skeletal system is divided into the axial skeleton which includes the skull, vertebrae, and thorax, and the appendicular skeleton which includes the limbs and their attachments.
4. Bones are classified based on their shape into long bones, short bones, flat bones, irregular bones, and sesamoid bones, with each shape relating to its particular functions.
section 1, chapter 8: joints
Joints, or articulations, are functional connections between bones that allow for movement. There are three main classifications of joints based on their structure and movement capabilities. Fibrous joints are immovable and connect bones using dense connective tissue. Cartilaginous joints have slight movement and connect bones with cartilage. Synovial joints are fully movable and contain synovial fluid within a joint cavity to facilitate movement. Common synovial joints include ball-and-socket joints, hinge joints, and gliding joints.
Bones and muscles
The document lists and describes the main bones and muscles in the human body, noting that bones are rigid and muscles are elastic. It provides details on the number of bones kids and adults have, names the longest, heaviest, and strongest bone as well as the smallest bone. The document also specifies the number of teeth kids and adults have and describes how muscles can contract and relax.
The Human Skeleton
The document summarizes the key functions of the human skeleton, including providing structure and shape to the body, protecting vital organs, enabling movement through joints and muscles, producing blood cells in the marrow, and storing important minerals like calcium. It notes there are 206 bones that work together with muscles, tendons, and joints to perform everyday movements and tasks.
Skeletal System
Bones are living tissues made of cells that take in nutrients and use energy. They are composed of compact bone and spongy bone, and are covered by a membrane called the periosteum. Bones provide structure, protect organs, allow for movement via muscle attachments, and store minerals. The internal structure contains cavities filled with marrow that produces red blood cells. Cartilage covers bone ends and absorbs shock. Bones are formed from cartilage that is replaced by mineral deposits from osteoblasts. There are 206 bones in the adult skeleton formed through fusion during development. Joints are where bones meet, separated by cartilage and connected by ligaments, enabling different types of movement.
Skeleton system
The skeleton provides 5 major functions: shape, support, body movement, protection, and blood cell formation. There are 4 types of bones: long, short, flat, and irregular. Joints allow movement and come in 4 types: ball and socket, hinge, pivot, and gliding. Ligaments connect bones, tendons connect muscles to bones, and cartilage protects joints. Synovial fluid reduces friction in joints. A healthy skeleton requires calcium, phosphorus, weight-bearing exercise, and avoidance of osteoporosis.
LT4.2 Skeletal System
There are two types of bone tissue: compact bone which is dense and forms the outer layer, and spongy bone which is less dense and found in low stress areas. Bones are composed of osteocytes embedded in bone matrix, as well as osteoblasts which build bone, osteoclasts which resorb bone, and osteogenic cells which develop into osteoblasts. A long bone has a central shaft made of compact bone surrounding marrow, expanded ends made of inner spongy and outer compact bone lined with marrow, and growth plates between the shaft and ends.
Functions and types of bones
The skeletal system has several key functions: providing protection for organs, storing minerals, and providing structure and support for muscle movement. There are different types of bones including long bones found in the limbs, short bones in the hands and feet, flat bones in the skull and pelvis, and irregular bones like those in the spine. Movement is enabled by muscles pulling on bones.
Bone presentation
The skeletal system consists of bones and tissues like tendons and ligaments that connect bones. It provides structure, protects organs, and allows movement. Babies have more bones than adults, which fuse together as people grow. Bones are living tissues made of hard material for strength surrounded by cells that allow growth and repair. Joints connect bones and allow movement through different types of connections like ball-and-socket joints in the shoulder.
Skeletal system
This document provides an overview of the skeletal system. It notes that the skeletal system provides structure and support to the body, protects internal organs, allows for muscle attachment, and stores important substances. The skeletal system includes around 200 bones separated into those in the arms/legs and those in the skull, spine, and ribs. Bones are living organs made of layers of tissue that come in different shapes and sizes depending on their function. Bones meet at joints and are covered in cartilage, which helps with movement and absorbing shock. The document discusses bone fractures, the bone repair process, and ways to keep bones healthy like drinking milk, exercising, and preventing osteoporosis. An activity is described to show bones are strongest in cylindrical shapes like

The skeletal system provides structure, protection, movement, and other functions for the body. It consists of both long bones and short bones, including those in the limbs, spine, skull, and pelvis. The skeletal system also produces blood cells and stores minerals. There are over 200 bones in the human body that can be classified by shape and location into groups like long bones, short bones, flat bones, and irregular bones.
Skeletal tissue
The skeletal system includes bones and cartilage that provide structure, allow for movement, and protect organs. The medical specialty of orthopedics focuses on treating the skeleton and joints. Skeletal tissue includes cartilage and bone, which are types of dense connective tissue. Bones have important functions like support, protection, movement, mineral storage, and blood cell production. Bone is made up of osteogenic cells, osteoblasts that form bone, osteocytes embedded in bone matrix, and osteoclasts that resorb bone. There are different types of bones like long bones with a diaphysis, epiphyses, and metaphysis. Bone formation occurs through intramembranous ossification or endochondral ossification. Common bone
Bones
This document provides an overview of bones, including their introduction, types, contents, and advantages. It notes that bones are rigid organs that make up the vertebrate endoskeleton. There are two main types of bones: soft bones like the nose and ear cartilage, and hard bones that make up the rest of the skeleton. Bone mainly consists of three parts - an outer compact bone, inner soft bone, and yellow marrow at the center. The key advantages of bones are that they protect internal organs, are the main source of blood production, give the body its structure, and bear the total body weight.
Types of muscle
There are three main types of muscle in the human body: striated muscle, smooth muscle, and cardiac muscle. Striated muscle is found in limbs and organs like the tongue and pharynx. It has long cylindrical fibers with blunt ends and uninucleated cells. Smooth muscle forms sheets in organs like the stomach and contracts slowly for long periods. Cardiac muscle is only found in the heart myocardium and has branched fibers that never fatigue.
Anatomy Unit 4 Notes: Muscle Types & Parts
There are three main types of muscle in the body - skeletal, cardiac, and smooth muscle. Skeletal muscle is voluntary and allows for body movement by connecting to bones. Cardiac muscle is found only in the heart and contracts involuntarily to pump blood. Smooth muscle is also involuntary and is located in organs to help move substances through the body. Muscles have several levels of organization from the whole organ down to individual protein filaments that allow for contraction.

Causes and characteristics of each condition are provided.
Anatomy unit 2 nervous system nerve impulse notes
Nerve impulses occur through a chain reaction of chemical events within neurons. When a neurotransmitter binds to a neuron, it causes depolarization by allowing sodium ions to enter the axon. This is followed by repolarization where potassium ions exit to regain the charge imbalance. This cycle of depolarization and repolarization propagates down the axon until the neurotransmitter is released at the axon terminal to stimulate the next neuron. For a nerve impulse to continue, sodium and potassium pumps must actively transport ions back to their resting positions inside and outside the axon respectively, requiring ATP. The myelin sheath increases nerve impulse speed by blocking some sodium and potassium channels along the axon similar to how freeways allow faster

It also reviews the locations and roles of the heart's five valves in regulating blood flow during heart relaxation and contraction.
Anatomy unit 3 cardio and vascular systems respiratory notes
The respiratory system brings oxygen into the body and removes carbon dioxide. It includes the nasal cavity, trachea, bronchi, bronchioles, lungs, diaphragm, and alveoli. During inhalation, the diaphragm contracts to increase lung volume and draw air in. During exhalation, the diaphragm relaxes to decrease lung volume and push air out. Gases diffuse between the alveoli and blood capillaries to oxygenate the blood and remove carbon dioxide. Common respiratory disorders include bronchitis, pneumonia, cystic fibrosis, asthma, tuberculosis, and chronic obstructive pulmonary disease.
Space Chapter 4 Notes
The document summarizes key concepts about the solar system. It describes the eight planets in our solar system, distinguishing between inner and outer planets. It also discusses Earth's rotation and revolution around the sun, as well as how our atmosphere protects us by filtering UV rays and creating a greenhouse effect. The moon and its effect on ocean tides is covered. Finally, it briefly touches on asteroids, comets, and meteors that also travel through our solar system.
Anatomy unit 2 nervous system eyeball dissection notes
The document provides instructions for dissecting an eyeball to identify its internal parts. It describes making cuts around the iris to remove the cornea and iris, then pouring out the humor to expose the choroid and retina. It lists the major external and internal parts of the eye, including the sclera, optic nerve, cornea, iris, pupil, lens, choroid, retina, and humor. A picture is referenced to show the location of these parts.
Anatomy unit 4 digestive and excretory systems excretory notes
The urinary/excretory system consists of the kidneys, ureters, bladder, and urethra. The kidneys filter the blood, removing waste and excess nutrients and reabsorbing needed water and nutrients. The ureters carry the filtered waste to the bladder, which stores it, and the urethra allows the waste to exit the body. The kidneys contain nephrons, which include a glomerulus and renal tubule, that perform filtration, reabsorption, and secretion to form urine and regulate water and electrolyte levels in the blood. Kidney dialysis is used when the kidneys fail to filter blood and remove wastes.
Anatomy Unit 3 Notes: The Stomach
The stomach digests food through both mechanical and chemical digestion. Mechanical digestion involves the stomach muscles churning food particles into a mass called a bolus. Chemical digestion uses gastric juices containing hydrochloric acid and enzymes like pepsin and rennin to break down proteins, carbohydrates, and fats in the bolus. The hormone gastrin stimulates gastric juice release in response to food entering the stomach. After about 3-4 hours of digestion, the partially digested mass called chyme exits the stomach through the pyloric sphincter into the small intestine for further digestion.
Biology Unit 4 Notes: Reproduction & Karyotyping
This document provides information about different types of reproduction, including sexual reproduction which requires two parents and produces genetically unique offspring, and asexual reproduction which requires one parent and produces genetically identical offspring. It also describes different forms of asexual reproduction like binary fission and budding. Additionally, it discusses karyotyping which is used to identify chromosomal disorders by analyzing chromosome pairs, and provides details about several chromosomal disorders including Down syndrome, Patau syndrome, Edward's syndrome, Klinefelter syndrome, and Turner's syndrome.
Anatomy Unit 3 Notes: The Small Intestine
The small intestine is divided into three regions: the duodenum, jejunum, and ileum. The duodenum secretes bile from the liver, pancreatic juice from the pancreas, and bicarbonate to balance pH. These secretions help to further break down proteins and lipids. Bile emulsifies lipids to aid absorption. Pancreatic juice contains enzymes that metabolize remaining biomolecules. The presence of lipids and proteins triggers the release of cholecystokinin, stimulating the release of bile and pancreatic juice into the small intestine for digestion. Absorption of nutrients occurs in the jejunum and ileum through microvilli in the smooth muscle wall.
Anatomy Unit 3 Notes: The Excretory System
The urinary/excretory system consists of the kidneys, ureters, bladder, and urethra. The kidneys filter the blood and remove waste and excess nutrients through urine. The ureters carry urine from the kidneys to the bladder, where it is stored until exiting the body through the urethra. The nephrons in the kidneys filter the blood and regulate water and electrolyte levels through selective reabsorption and secretion into the urine. Kidney dialysis is used when the kidneys fail by filtering the blood mechanically.

Anatomy Unit 4 Notes: Bone Types, Function, The Skeleton
This document provides information on bone anatomy and composition. It describes the main skeletal parts as bones, joints, and cartilage. Bones provide structure, protection, movement, and storage functions. They are connected through joints filled with cartilage, which allow for movement. There are four main types of bones: long bones, which provide structure and support to the limbs; short bones, which allow for wider movement in areas like the wrist and ankle; flat bones, which protect soft tissues like the skull and ribs; and irregular bones, to which muscles and tendons typically attach, like the vertebrae and hip bones. Bones have both compact outer layers and spongy inner layers, and a long bone specifically has a diaphysis shaft and

This document provides information about bones, including their definition, functions, classification, structure, and chemical composition. It notes that bones are composed of calcium phosphate and carbonate. There are two main types of bone regions - axial and appendicular. The axial skeleton includes 80 bones such as the skull and vertebrae, while the appendicular skeleton contains 126 bones like the limbs. Bones are also classified by shape as long, short, flat, or irregular. Long bones make up the limbs and provide support and structure. The structure of bones includes compact outer layers and spongy inner layers. Chemically, bones contain both organic components like collagen and cells, and inorganic mineral salts that give bones their hardness.
skeletal system.pdf
The skeletal system consists of bones, cartilage, joints and ligaments. Bones provide structure, protect organs and allow movement. There are two types of ossification - intramembranous which forms flat bones, and endochondral which forms most other bones through cartilage models. Bones are living tissues that continually remodel through the actions of osteoblasts which build bone and osteoclasts which break it down. Nutrition, exercise, hormones and aging all impact bone remodeling and strength.

Bones, Joints, and the Architecture of Movement: Exploring the Skeletal System
Title: Bones, Joints, and the Architecture of Movement: Exploring the Skeletal System
Introduction:
Welcome to our engaging SlideShare presentation on the Skeletal System & Joints, where we embark on a fascinating exploration of the framework that supports our bodies and facilitates movement. Join us as we delve into the intricate world of bones, joints, and the dynamic interplay that shapes our mobility and stability.
The skeletal system serves as the foundation of our anatomy, providing structural support, protection for vital organs, and a framework for locomotion. Comprised of bones, cartilage, ligaments, and tendons, this complex system forms the structural scaffold upon which our bodies are built.
In this presentation, we'll take a closer look at the anatomy of bones, from their composition and classification to their roles in mineral storage and blood cell production. Through detailed illustrations and interactive diagrams, we'll explore the dynamic nature of bone remodeling and the factors that influence bone health and density.
But bones alone do not account for the versatility of human movement. Joints, the articulations where two or more bones meet, play a crucial role in facilitating motion and absorbing impact. From synovial joints like the knee and shoulder to fibrous and cartilaginous joints, we'll unravel the mechanics of joint structure and function.
Together, the skeletal system and joints form a complex network that enables us to walk, run, jump, and perform a myriad of daily activities. Whether you're a student studying anatomy, a fitness enthusiast seeking to optimize performance, or simply curious about the mechanics of the human body, our presentation offers valuable insights into the wonders of the skeletal system and joints.
Join us as we embark on a journey through the bony landmarks and articulations that define our physical form and discover the intricate architecture of movement hidden beneath our skin.
Basic ap chapter 6 powerpoint 2017
The skeletal system performs several critical functions:
1. It supports the body and facilitates movement by providing attachment points for muscles and acting as levers.
2. Bones protect internal organs such as the lungs, heart, and brain.
3. The skeletal system stores and releases minerals and produces blood cells. Bones store minerals like calcium and release them when needed, and bone marrow produces red blood cells, white blood cells, and platelets.
Skeletal system
The skeletal system consists of 206 bones and connective tissues that connect them. It performs vital functions like providing a framework to support the body, protecting organs, enabling movement through muscle attachment to bones, producing blood cells, and storing minerals. The skeletal system includes long bones in the limbs, short bones in the hands and feet, flat bones like in the skull, and irregular bones like vertebrae. It is divided into the axial skeleton of the trunk and appendicular skeleton of the extremities. The skull contains cranium and facial bones that protect the brain and house senses.
The skeletal system
The skeletal system has three main functions: providing structure and shape to the body, protecting vital organs, and allowing for bodily movement. It is made up of 206 bones that form the axial skeleton (skull, vertebrae, ribs, sternum) and appendicular skeleton (limbs and girdles). Bones are living tissues composed of compact bone, spongy bone, bone marrow, and various bone cells. They provide structure through their interaction with muscles, tendons, and ligaments at joints like the ball-and-socket hip. The skeletal system also plays roles in blood cell production and mineral storage.

The document describes the classification and structure of bones. It discusses the five categories of bone classification based on shape - long, short, flat, irregular, and sesamoid. It then describes the gross anatomy and microscopic structure of long bones, including their diaphysis, epiphyses, epiphyseal plate, periosteum, endosteum, and medullary cavity. Finally, it discusses the histology and microscopic anatomy of compact and spongy bone, including osteons, lacunae, lamellae, central canals, Volkmann canals, trabeculae, and the cells and tissues involved in bone formation and structure.
Introduction to the Skeletal System.pptx
The skeletal system consists of 206 bones that provide structure, protect organs, allow movement, and produce blood cells. There are four types of bones: long bones like the femur; short bones like wrist bones; flat bones like the skull; and irregular bones like vertebrae. The skeletal system works with muscles to support the body, enable movement through leverage, and shield delicate tissues.
Skeletal_System.ppt
The document discusses the classification and structure of bones. Bones are classified based on their shape as long, short, flat, irregular, or sesamoid. Long bones have a shaft and expanded ends, and contain mostly compact bone. Short bones are cube-shaped with mostly spongy bone. Flat bones are thin with layers of compact bone around spongy bone. Irregular bones have irregular shapes. Microscopically, bones contain compact and spongy bone. Compact bone is dense with concentric circles while spongy bone has trabeculae and spaces. Bones provide structure, protection, movement, mineral storage, and blood cell production.
Human body & Musculoskeletal system.pdf
Throughout history, the symbol of the skull and crossbones has served as a representation of mortality, likely owing to the fact that following death and decay, bones are the sole remnants. Many individuals perceive bones as inert, desiccated, and fragile. While these attributes accurately portray the bones of a preserved skeleton, the bones within a living human being are profoundly alive. Living bones exhibit strength and flexibility, serving as the primary components of the skeletal system.

2. Bones are made of both living and non-living materials. The living parts include bone cells while the non-living parts include the bone matrix made of collagen and hydroxyapatite. Bones can be classified based on their microscopic structure and location in the body.
3. The skeletal system allows for movement through joints which can be fibrous, cartilaginous, or synovial. The main types of synovial
4 Skeletal System (Unit-IV)-for Stds.ppt
The human skeleton is the internal framework of the body. It is composed of around 270 bones at birth – this total decreases to around 206 bones by adulthood after some bones have fused together.
The bone mass in the skeleton reaches maximum density around age 21. The human skeleton can be divided into the axial skeleton and the appendicular skeleton.
The axial skeleton is formed by the vertebral column, the rib cage, the skull and other associated bones. The appendicular skeleton, which is attached to the axial skeleton, is formed by the shoulder girdle, the pelvic girdle, and the bones of the upper and lower limbs.
he skeleton serves six major functions: support, movement, protection, production of blood cells, storage of minerals and endocrine regulation.
The skeleton provides the framework which supports the body and maintains its shape. The pelvis, associated ligaments and muscles provide a floor for the pelvic structures. Without the rib cages, costal cartilages, and intercostal muscles, the lungs would collapse.
LT4.2 Skeletal System
There are two types of bone tissue: compact bone which is dense and forms the outer layer, and spongy bone which is less dense and found in low stress areas. Bones are composed of osteocytes embedded in bone matrix, as well as osteoblasts which build bone, osteoclasts which resorb bone, and osteogenic cells which develop into osteoblasts. A long bone has a central shaft made of compact bone surrounding marrow, expanded ends made of inner spongy and outer compact bone lined with marrow, and growth plates between the shaft and ends.
Aaaaaa a skeletal system
The skeletal system has several key functions: providing points of attachment for muscles to facilitate movement, supporting the body, protecting internal organs, producing blood cells, and storing minerals. It consists of the axial skeleton including the skull, spine, ribs and sternum, and the appendicular skeleton including the shoulders, arms, hips and legs. Bones come in four basic shapes and have a layered structure consisting of periosteum, compact bone, spongy bone and bone marrow. Joints allow bones to move and come in both immovable and movable forms including ball-and-socket, hinge, pivot and gliding joints.

Anatomy-Bad Fish Unit: Digestion Notes
This document describes digestion that occurs in the mouth, esophagus, stomach, and small intestine. In the mouth, food is mechanically and chemically broken down by teeth and saliva enzymes. The chewed food or bolus is then swallowed through the esophagus using peristalsis. In the stomach, the bolus is further broken down by stomach muscles and enzymes in gastric juice. When fully digested, the liquid chyme exits the stomach into the small intestine where bile, pancreatic juice, and bicarbonate aid in further digestion before nutrients are absorbed in the jejunum and ileum.
Anatomy-Bad Fish Unit: Cardiovascular Notes
The heart has four chambers separated by a septum, with two atria that receive blood and two ventricles that pump blood out. It is surrounded by membranes and layers. Veins carry deoxygenated blood into the right atrium while pulmonary veins carry oxygenated blood into the left atrium. The pulmonary artery carries blood from the right ventricle to the lungs and the aorta carries it from the left ventricle throughout the body. Valves ensure blood flows in one direction. The cardiac cycle involves the heart relaxing to fill with blood then contracting to pump it out in two phases controlled by the conduction system.
MSTA 2018: "Starting From Scratch" (Katelyn Rozema)
This document outlines a workshop on creating curriculum units from scratch using case studies and new standards. The workshop agenda includes an introduction, explaining why use case studies, and walking through the steps of transforming a case study into a curriculum. The steps include: reading the case study and identifying vocabulary and questions; connecting disciplinary core ideas (DCIs) to the questions; determining the driving question and final goals; finding activities that incorporate science practices; and finalizing the curriculum with assessment and starting the case study. The goal is to share the presenter's experience developing original units and help teachers who teach without prepared curricula.
Ths general biology unit 4 heredity non mendelian genetics notes_v1516
This document discusses different types of non-Mendelian genetics including polygenic traits which are influenced by multiple genes, codominant traits where both alleles are expressed together, incomplete dominance where the heterozygote exhibits a blending of traits, and sex-linked traits located on the sex chromosomes. Examples are provided for each type to demonstrate inheritance patterns that differ from simple Mendelian genetics.
Ths general biology unit 4 heredity mendelian genetics notes_v1516
This document summarizes key concepts in Mendelian genetics. It explains that Gregor Mendel studied trait inheritance in pea plants and discovered that traits can be dominant or recessive. Dominant traits always appear if present, while recessive traits only appear if an organism inherits two recessive alleles. An organism's genotype describes its genetic makeup, while its phenotype describes its physical traits. Punnett squares are used to predict the probability that offspring will inherit different combinations of alleles from their parents.
Ths general biology unit 4 heredity karyotyping notes_v1516
Karyotyping is used to identify chromosomal disorders by staining and organizing chromosomes from longest to shortest based on banding pattern. Abnormalities include an extra chromosome like Trisomy 21 which causes Down Syndrome characteristics such as cognitive impairment and heart defects, or a missing sex chromosome as in Turner's Syndrome where females are sterile with short stature.
Ths general biology unit 4 heredity reproduction and meiosis notes_v1516
Meiosis is the process of cell division that produces gametes (sperm and egg cells) for sexual reproduction. It involves two cell divisions that result in four haploid cells, each with half the number of chromosomes as the original cell. This ensures that offspring have a full set of chromosomes when fertilization occurs. The main features of meiosis include homologous chromosome pairing, crossing over to increase genetic variation, and independent assortment of chromosomes into daughter cells through the first and second meiotic divisions. Errors in meiosis can result in gametes with an abnormal number of chromosomes, causing genetic disorders.
Ths general biology unit 4 heredity protein synthesis notes_v1516
Protein synthesis involves two main steps: transcription and translation. In transcription, the DNA code is copied into messenger RNA (mRNA) in the cell nucleus. This mRNA then leaves the nucleus and the code is translated during translation when transfer RNA (tRNA) matches mRNA codons and brings corresponding amino acids to form a protein, guided by ribosomal RNA (rRNA). Mutations occur when the DNA code changes, leading to errors in protein synthesis when the wrong tRNA and amino acids are matched to the altered mRNA codons.
Ths general biology unit 4 heredity cell cycle notes
Cell division allows cells to grow, repair, replace damaged cells, and reproduce. There are two main types of cell division: mitosis and meiosis. The cell cycle is the process cells use to prepare for cell division. It includes interphase, where the cell grows and duplicates its DNA, and the M phase where the cell divides. Errors in the cell cycle checkpoints during interphase can allow defective cells to divide uncontrollably and cause cancer.
Ths general biology unit 4 heredity dna replication notes
DNA replication is necessary for cell division to create a copy of the DNA for each new cell. Messelson and Stahl discovered that DNA replication is a semi-conservative process where the original DNA molecule splits into two new molecules, each with one original strand and one newly synthesized complimentary strand. The basic steps of replication are to unwind the DNA strands, separate the strands, and then make complimentary copies of each single strand to result in two new DNA molecules with one old and one new strand each.
Ths general biology unit 4 heredity dna structure and function notes
DNA stores genetic instructions in the form of a code made up of four nitrogenous bases: adenine (A), thymine (T), guanine (G), and cytosine (C). DNA has a double-stranded helical structure, with the strands bonded together via complementary base pairing between A and T and between G and C. According to Chargaff's rule, the percentage of A bases is always equal to the percentage of T bases, and the percentage of G bases is always equal to the percentage of C bases within a DNA sample. The two strands of DNA run in opposite directions of each other (anti-parallel) and form a double helix.
Ths general biology unit 3 cell processes homeostasis and feedback mechanisms...
Homeostasis refers to maintaining internal balance, and feedback mechanisms are the involuntary chemical processes that bring the body back to its normal state when something causes internal changes. There are two main types of feedback mechanisms: negative feedback mechanisms return the body to its normal state, like shivering and sweating to regulate temperature and insulin to regulate blood sugar levels. Positive feedback mechanisms cause more change to happen, though few homeostatic responses use this type, such as oxytocin causing stronger contractions during childbirth to help deliver the baby.
Ths general biology unit 3 cell processes cell membrane transport notes_v1516
Cell membranes allow transport of molecules into and out of cells through diffusion, facilitated diffusion, osmosis, and active transport. Diffusion and facilitated diffusion move particles from high to low concentration without energy, while osmosis moves water molecules and active transport moves particles against concentration gradients, requiring ATP energy. Cells regulate transport to take in useful nutrients and remove waste.
Ths general biology unit 2 our bodies living organization notes_v1516
All living things are made of cells and molecules that are organized into different levels. Cells are the basic units of life that make up tissues, organs, organ systems, and the overall organism. All cellular processes require energy and involve the movement and reactions of molecules like carbon, hydrogen, oxygen, nitrogen, phosphorus, and sulfur. Homeostasis is maintained involuntarily within cells and organisms through processes that keep internal stability and balance. Cells become specialized by taking on unique shapes and functions to complete specific roles that together support homeostasis at the organism level. The main human organs include the brain, heart, lungs, liver, stomach, intestines, and kidneys, each of which performs crucial functions for keeping humans alive and healthy.
Ths general biology unit 2 our bodies cells and organelles notes_v1516
(1) Cells are the basic unit of life and can be either unicellular (single-celled) or multicellular (many cells). Cells contain organelles that help them complete important processes.
(2) Key organelles include the nucleus, ribosomes, endoplasmic reticulum, Golgi body, mitochondria, chloroplasts, cell membrane, and cell wall.
(3) Organelles are found inside cells to help them carry out specialized functions like protein production, cellular respiration, and photosynthesis. The endosymbiotic theory explains how organelles may have originally been independent organisms that lived inside host cells and eventually became permanent cell structures.
Ths general biology unit 2 our bodies cell reactions and enzymes notes_v1516
Cellular reactions use enzymes to break down molecules, form larger molecules, and facilitate energy storage and release using ATP and ADP. Enzymes are proteins that catalyze chemical reactions by lowering their activation energy through a specific lock-and-key structure that allows substrates to bind at the enzyme's active site. Denaturing enzymes through extreme heat or chemicals causes their structure to unravel and disrupt their active site, preventing them from catalyzing reactions.

This document discusses key concepts around biodiversity, ecosystem stability, and succession. It defines biodiversity as the variety of living organisms in an ecosystem, and notes that greater biodiversity leads to greater ecosystem stability. Succession is introduced as the process by which the structure of a community changes over time due to events like fires, storms, or human activity. There are two types of succession: primary succession, which occurs in a new area without soil or life, and secondary succession, which follows a disruption to an already established habitat.

This document discusses climate change and human impacts on the environment. It defines key terms like climate, weather, and greenhouse gases. It explains how the greenhouse effect traps heat in the atmosphere and is impacted by carbon dioxide, methane and water vapor. It also discusses how climate naturally changes over time but that human activities like fossil fuel use, pollution, and ecosystem damage are exacerbating climate change. It provides examples of evidence for climate change through changing ice caps, storms, and plant/animal distributions. Finally, it briefly covers the concepts of biomagnification and invasive species introduction.

Anatomy unit 5 skeletal and muscular systems bone types and composition
- 1. ANATOMY UNiT 5 NOTes: BONe TYpes & COMpOsiTiO
- 3. (2) Skeletal Function 1. Support – – – Framework for posture Limbs act as pillars Rib cage supports thoracic wall 2. Protection - Ribs protect lungs and heart Skull protects brain Vertebrae protect spinal cord 3. Movement - Attachment sites for muscles and tendons Muscles use bones as levers Joints between allow for range of motion
- 4. …Function Cont’d… 4. Mineral & Growth Factor Storage - Reservoir for calcium and phosphate Releases minerals into blood Growth factors (insulin, transforming factor, morphogenic proteins) in bone 5. Blood Cell Formation - Marrow within cavities of bones (primarily long) Marrow initiates hematopoeisis (blood cell formation)
- 5. (3) How are bones hinged together? • Joints: Connection between two bones. – Filled with cartilage (padding) • Allow for wider range of movement. – Circular – Angular • Reduce rigidity of bone structure. • *Cartilage within joints (in between bones) provides shock absorption, and decreases friction.
- 6. (4) Injuring Joints • Sprains: – Ligaments reinforcing a joint are stretched or torn – If torn badly, can be replaced with muscle – Usually result from inflexibility or irregular movement • Dislocations: – Bones are forced out of alignment – Usually result from serious falls and contact sports – Results in stretching of joint ligaments, leading to future dislocations
- 7. (5) What are the Bone Regions? • Axial – Down the center of body – Skull, vertebral column, rib cage, center pelvis • Appendicular – Off the sides of body – Upper and lower limbs, shoulder and hip bones
- 9. (6) What are the types of bones? • • • • Long Short Flat Irregular
- 11. (7) Long Bones • • • • Longer than they are wide Has a shaft and 2 ends Weight bearing bones (like steel beams) Provide the greatest structure and support • Examples: – All limb bones – Except…. Kneecap, Wrist and Ankle bones
- 13. (8) Short Bones • Cube Shaped • Allow for wider range of movement • Examples: – Wrist – Ankle
- 15. (9) Flat Bones • Thin, flat and curved • Protect soft tissue (like plates of armor) • Examples: – Sternum – Shoulder blades – Ribs – Skull bones
- 17. (10) Irregular Bones • Complicated, unusual shapes • Muscles, tendons, ligaments usually attach to these • Examples: – Vertebrae – Hip bones
- 19. (11) Bone Structure • Unique based on location + bone type. • Compact Bone (Outer Layer): – Dense – Smooth and Solid to naked eye • Spongy Bone (Inner Layer): – Hole-y (like a honeycomb) – Made of small needle-like, flat pieces called “trabeculae” – Open spaces between trabeculae are filled with red or yellow bone marrow
- 22. (12) Structure of a Long Bone • Diaphysis: – Center, main shaft – Long part of bone – Made of very thick compact bone surrounding a central marrow cavity • Epiphysis: – – – – Ends of bone Wider than diaphysis Made of compact bone which surrounds spongy bone. Joint surface of each epiphysis is covered with hyaline cartilage
- 23. • Epiphyseal Line: – Remnant of Epiphyseal Plate – Found in adult bones – Shows amount of cartilage growth during adolescence • Membranes: – Periosteum = Around the outside • Richly supplied with nerve fibers, lymphatic vessels and blood vessels • Provides anchoring points for tendons and ligaments – Endosteum = Around the inside • Surrounds the spongy bone
- 25. (13) Chemical Composition of Bone • Contains organic & inorganic components • Organic: – Cells (osteoblasts, osteocytes, osteoclasts) – Osteoid • Made of glycoproteins and collagen fibers • Secreted by osteoblasts • “filler matrix” around cells – Contribute to flexibility and tensile strength • Inorganic: – Mineral Salts (calcium phosphates) – Contribute to hardness of bone (allowing for compression resistance)
