The skeletal system provides support, protection, movement, blood cell production, and mineral storage. There are 206 bones in the adult skeleton divided into the axial skeleton of the skull, vertebrae, ribs, and sternum, and the appendicular skeleton of the shoulders, arms, hands, hips, legs and feet. Bones are composed of compact bone on the outside and spongy bone on the inside or at the ends of long bones. Bone marrow inside bones produces red blood cells, white blood cells and platelets. Fractures occur when bones are broken, ranging from simple fractures to compound fractures where the bone protrudes from the skin. The body repairs fractures through formation of a blood clot, cartilage, and

PE Skeletal System
The skeletal system provides structure and protection for the body through bones and joints. It allows for movement and houses bone marrow. Bones are made up of three layers - a hard outer layer, spongier inner layer, and bone marrow. When born there are around 300 bones, which fuse together into 206 bones as one grows. Exercise and consuming calcium through milk and dairy helps keep bones strong and healthy.
The muscular system
The document discusses the three main types of muscle in the body: smooth muscle found in internal organs, cardiac muscle only found in the heart, and skeletal muscle attached to bones. Skeletal muscle is voluntary and arranged in opposing pairs to allow movement. Skeletal muscle contains two types of fibers - slow-twitch for endurance and fast-twitch for strength but less endurance. Muscles require ATP from cellular respiration or anaerobic fermentation to contract, and even at rest need energy to function. Muscular dystrophy is an inherited disease that destroys skeletal muscles over time.
Chapter 14 Notes
The skeleton serves four main functions: supporting the body, protecting organs, allowing blood cell production in the bone marrow, and providing attachment points for muscles. The skeleton is made up of 206 bones, including 22 in the skull. Bones are living tissues composed of solid bone, spongy bone, cartilage, ligaments, and bone marrow. The skeleton grows in size and complexity as a person ages.

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.
A and P Osseous tissue
Bone is a type of connective tissue composed of collagen fibers, ground substance, and hydroxyapatite which gives it strength and hardness. There are two main types of bone tissue - compact bone which is dense and strong, and spongy bone which is lighter. Bones grow in length at the epiphyseal plate through the production and replacement of cartilage with bone, and in width through appositional growth where new bone is laid down on the surface.

- The document also mentions that there are three types of muscles in the body including smooth, cardiac and skeletal muscles which are attached to bones by tendons and allow for movement.
The skeletal system
The skeletal system is composed of bones and joints which provide structure, protect organs, and enable movement. It includes elements like the skull, rib cage, backbone, and limbs. Joints are where two bones meet and are held together by ligaments, allowing movement except in the skull. There are different types of joints like hinge, ball-and-socket, and pivot joints. Muscles connect to bones via tendons and work with the skeletal system to produce movement, with some muscles being voluntary and others involuntary.
Bones
Bones have several important functions in the body. They provide structure and support, protect internal organs, assist with movement, store minerals and produce blood cells. Bones are made up of two types of tissue - compact bone on the outside and spongy bone on the inside. Spongy bone contains bone marrow which produces blood cells. Bones form during development through two processes - intramembranous ossification where mesenchymal cells form bone tissue, and endochondral ossification where cartilage is replaced with bone. Theories on how the earliest bones may have evolved include the hardening of cartilage over time or the formation of a blood clot within an organism that later hardened into bone.

Ligaments: Bands of strong connective tissue called ligaments hold bones together.
Functions of Ligaments:
Attach bones to bones
Provide stability
Tendons: Tendons are bands of tissue that connect the ends of a muscle to your bone.
Functions of Tendons:
Attach muscles to bones
Anchors muscle to bone for movement
Joints: A joint is where two or more bones in the body come together.
Anatomical position:
Anatomical position, or standard anatomical position, refers to the positioning of the body when it is standing upright and facing forward with each arm hanging on either side of the body, and the palms facing forward. The legs are parallel, with feet flat on the floor and facing forward.
Bones – types, structure, growth and ossification:
Bones:
Bone are specialized forms of strong connective tissue that forms the skeleton of the body.
It is composed of calcium phosphate and calcium carbonate.
It also serves as a storage area for calcium, playing a large role in calcium balance in the blood
The smallest bone in the human body is called the stirrup or stapes bone, located deep inside the ear & The longest bone in the human is called the femur.
Classification or types of bones:
Bones are divided into 5 types.
Long Bone
Short Bone
Flat Bone
Irregular Bone
Sesamoid Bone
1. Long Bone:
A long bone is one that is cylindrical in shape, being longer than it is wide.
Shape of a bone, not its size.
Long bones are found in: Arms (humerus, ulna, radius) & fingers (metacarpals, phalanges) and also Legs (femur, tibia, fibula),
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.

Bones
Bones are made of connective tissue called osseous tissue. There are 206 bones in the human skeleton that are divided into the axial skeleton (skull, vertebrae, ribs) and appendicular skeleton (shoulder, hip, arm and leg bones). Bones provide structure, support, protection and allow for movement. They also store minerals and marrow where blood cells are formed. Bones are composed of compact bone on the outside and spongy cancellous bone on the inside. The four main bone classifications are long bones, short bones, flat bones, and irregular bones. Long bones make up the limbs and have a diaphysis shaft and epiphyses ends. Bone cells include osteoblasts that build bone
Bonetissuetoskeletalsystemppt 110126162139-phpapp02
The skeletal system is composed of bones and associated tissues that perform several essential functions:
1. Support - Bones provide structural support for the body and protection for internal organs.
2. Movement - Skeletal muscles use bones as levers to enable movement of the body.
3. Mineral storage - Bones store minerals like calcium and phosphorus.
There are over 200 bones in the human body that are classified as long, short, flat, or irregular. Bones are living tissues composed of cells like osteoblasts, osteocytes, and osteoclasts embedded in an organic bone matrix and inorganic minerals. Compact bone forms the dense outer layer while spongy bone composes the inner layer. Long bones have
Skeletal system
The skeletal system consists of 206 bones that make up two divisions: the axial skeleton and appendicular skeleton. The axial skeleton includes the skull, vertebral column, and thorax, while the appendicular skeleton includes the upper and lower limbs. Bones can be classified by their shape as long, short, flat, or irregular. Each bone has specific structures including compact and spongy bone, periosteum, endosteum, and markings for muscle attachments. Bones provide structure, protection, movement, mineral storage, and blood cell production. They continuously remodel in response to hormones and mechanical stresses.

Bone provides structure and support to the body through its skeleton framework. It has several important functions including support, protection, movement, mineral storage, and energy storage. Bone is composed of cells, collagen fibers, and hydroxyapatite crystals that calcify and harden it. There are 206 bones in the adult human skeleton that are divided into the axial skeleton (skull, vertebral column, ribs) and appendicular skeleton (limbs). Bones can be classified based on their location, size, shape and internal structure. Long bones are found in the limbs and have a shaft and expanded ends. Bone tissue is either compact or spongy and contains osteocytes, osteoblasts, and osteoclasts that allow bone to

bones
Bones are rigid organs that form the endoskeleton and have several important functions, including movement, support, protection and storage of minerals. There are two types of ossification that form bones - intramembranous and endochondral ossification. Intramembranous ossification forms some flat bones directly in fibrous membranes, while endochondral ossification first forms cartilage templates that are later replaced by bone. Long bones develop primarily through endochondral ossification, beginning as cartilage that is later invaded by blood vessels and replaced with spongy bone. Growth plates allow bones to lengthen, and remodeling allows bones to increase in thickness. Calcium homeostasis and bone health rely on adequate vitamin D, which facilitates intestinal

The human skeleton is composed of 206 bones that provide structure, protect internal organs, allow for movement, and store minerals. There are 80 axial bones including the skull and vertebrae, and 126 appendicular bones such as the arms, legs, shoulders, and hips. Bones are living tissue composed of compact, cancellous, and subchondral bone tissues. The skeleton works with muscles to facilitate movement and provides anchors for muscles. Bones also serve important metabolic functions like mineral storage and blood cell production.

Lecture 1 (introduction to bone)
The document discusses the structure and functions of bones in the human skeletal system. It notes that bone is living tissue that is constantly being recreated. Bones provide structure and protection to the body, allow for movement through attachment of muscles and acting as levers, and store minerals and produce blood cells. The five categories of bone are defined based on shape: long bones, short bones, flat bones, irregular bones, and sesamoid bones.
Anatomy and Physiology on the musculoskeletal system
The musculoskeletal system is made up of bones, cartilage, ligaments, tendons and muscles, which form a framework for the body. Tendons, ligaments and fibrous tissue bind the structures together to create stability, with ligaments connecting bone to bone, and tendons connecting muscle to bone.

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.

Surface of the Earth
This document discusses processes that shape Earth's surface, including mountain building and erosion. It describes three main ways that mountains form: through folding at convergent plate boundaries, movement of chunks of land at faults, and volcanic activity. Erosion is identified as a major destructive process that causes land and rock to wear down over time. The formation of soil and role of glaciers in shaping the surface are also covered. The document concludes with an overview of the rock cycle and the three main types of rocks: igneous, sedimentary, and metamorphic.
Types of Volcanoes
Volcanoes form in different types depending on the composition of the magma and tectonic setting, with shield volcanoes being non-explosive and forming from basalt in oceanic settings, composite volcanoes sometimes having explosive eruptions from more viscous magma in continental settings, and cinder cones being the smallest from pyroclastic eruptions.
Volcanoes chapter 29
The eruption of Mount St. Helens in 1980 caused its height to decrease significantly. An earthquake triggered a landslide that caused a bulge on the mountain to eject magma, water, and gases. Volcanic activity occurs mainly at plate boundaries and is caused by melting of solid rock into magma under conditions of high temperature and pressure.
Exploring dominant and recessive traits
This document discusses dominant and recessive genetic traits. It explains that traits are passed down from parents through genes, with each person receiving half their genes from each parent. Dominant traits are stronger and mask recessive traits, while recessive traits only appear in later generations if both parents carry the recessive gene. Common traits like eye color, hair color, and skin pigmentation can be either dominant or recessive. The document includes questions and activities for students to identify dominant and recessive traits in themselves and their classmates.
Patterns of Heredity
This document summarizes key concepts in genetics, including Gregor Mendel's experiments with pea plants, dominant and recessive traits, Punnett squares, homozygous and heterozygous organisms, and more complex patterns of heredity such as incomplete dominance, co-dominance, multiple alleles, and polygenic traits. Vocabulary terms are defined including dominant trait, recessive trait, homozygous, heterozygous, purebred, and hybrid. Examples are provided to illustrate concepts like incomplete dominance showing trait blending, co-dominance where two dominant genes are present for one trait, and polygenic traits controlled by many interacting genes.
Earthquakes ii
Earthquakes originate from a focus point within the earth and seismic waves travel outward, reaching the surface at the epicenter above the focus. Body waves including P-waves and S-waves originate at the focus and travel through the earth, while surface waves cause more damage when they reach the epicenter. Faults occur along tectonic plate boundaries and are classified as normal, reverse, or strike-slip depending on whether the rocks above the fault plane move down, up, or sideways relative to the other side.
Earthquakes
Here are three questions from the section with the answers:
1. What causes convection currents in the mantle?
- Convection currents in the Earth are caused by the Earth's hot inner core heating the magma within the mantle.
2. What is a fault?
- A fault is a fracture, or break, in Earth's lithosphere. Rocks on either side can slide slowly along the fault or stick together, building stress until releasing in an earthquake.
3. Where do most earthquakes occur?
- About 80% of all earthquakes occur in a belt around the edges of the Pacific Ocean, near plate boundaries like the San Andreas Fault where the North American and Pacific plates meet.
Genetics ii
This document discusses Gregor Mendel's pioneering work in genetics and heredity by breeding pea plants. It then introduces more complex patterns of heredity beyond Mendel's findings, including incomplete dominance where traits blend, codominance where two dominant genes for a trait are both expressed, multiple alleles where traits have more than two variations, and polygenic traits which are influenced by multiple interacting genes.
Plate tectonics ch 28.2
The document summarizes key aspects of plate tectonic theory:
1) Plate tectonics explains the movement of continents and geological events like earthquakes and volcanoes. Early theorists like Alfred Wegener and Harry Hess contributed to developing this theory in the early 20th century.
2) Sea floor spreading was proposed by Hess and coined by Robert Dietz, describing how new ocean crust forms along mid-ocean ridges as the plates spread apart.
3) Magnetic patterns in ocean crust provided evidence that Earth's magnetic poles switch polarity over time, recording a history of plate movements.
Exploring dominant and recessive traits
This document discusses dominant and recessive genetic traits. It explains that traits are passed down from parents through genes, with each person receiving half their genes from each parent. Dominant traits are stronger and mask recessive traits, while recessive traits only appear in later generations if both parents carry the recessive gene. Common traits like eye color, hair color, and skin pigmentation can be either dominant or recessive. The document includes questions and activities for students to identify dominant and recessive traits in themselves and their classmates.
Create an earth’s layers poster
The document provides instructions for creating an Earth's layers poster by having students 1) diagram and label the layers of the Earth including the inner core, outer core, mantle, asthenosphere, lithosphere, and crust, 2) list and describe each of the 6 layers on a separate sheet of paper, and 3) attach the diagram and description sheets together before turning the poster in, using their book or the Internet for reference.
Chapter 28.1 modern geology
Geology is the study of Earth's rocks and materials. Nicholas Steno developed ideas in the 1600s about how rocks and fossils form using the analogy of shark teeth resembling stones found in rocks. These ideas formed the basis for relative dating techniques. Relative dating determines the order events occurred in by applying principles like superposition, original horizontality, lateral continuity, cross-cutting relationships, inclusions, and faunal succession to analyze rock layers and fossils. Earth's age was originally calculated to be between 10-100 million years but is now estimated at 4.6 billion years based on radioactive dating techniques.

Comparing Atoms and Periodic Table
This document discusses atomic structure and the periodic table. It explains that the atomic number is the number of protons in an atom, which distinguishes one element from another. The mass number is the total number of protons and neutrons. Isotopes are atoms of the same element with different numbers of neutrons. Electrons orbit the nucleus in energy levels. The periodic table organizes elements based on their properties and places them in rows and columns according to atomic number.
Atomic structure18.1
This chapter discusses atomic structure and the development of atomic models from Dalton to Schrodinger, including Thomson's discovery of electrons, Bohr's model of electrons orbiting the nucleus in fixed orbits, and Schrodinger's electron cloud model showing electron location is probabilistic rather than definite. The chapter also defines subatomic particles like protons, neutrons, electrons and their relative masses and charges, and introduces concepts like atomic number, isotopes, and the periodic table which are explored further.
Creating a Science Fair Project
The document provides instructions for creating a science fair project, including choosing a question, conducting research to form a hypothesis, designing an experiment to test the hypothesis, collecting and recording data, analyzing results to evaluate the hypothesis, and presenting findings in a display board and notebook. Key components that will be graded are an abstract, procedure, results displayed through charts and graphs, and conclusion stating whether the hypothesis was supported. Students can earn course units for completing a science fair project.
Properties of Liquids and Gasese
Archimedes' Principle states that the buoyant force on an object in a fluid is equal to the weight of the fluid displaced. Boyle's Law explains that the volume of a gas decreases as pressure increases. Charles' Law describes how the volume of a gas increases as temperature rises, such as with balloons or bicycle tires.
Classification of Matter
The document discusses the classification and properties of matter, explaining that matter can be classified as either mixtures which contain more than one type of matter, or as substances which cannot be separated into different types of matter. It also describes the four states of matter - solid, liquid, gas, and plasma - and how temperature influences the movement and arrangement of molecules in each state. Measurement techniques for determining the volume, mass, and amount of different types of matter are also outlined.
Electricity and circuits
This document provides an overview of electricity and electrical circuits. It defines electricity as the flow of electric current and notes that electricity is caused by an imbalance of positive and negative charges. It then explains that an electrical circuit provides a complete path for electricity to flow through devices. Common examples of circuits include household wiring and car batteries. The document discusses the differences between open and closed circuits and how switches are used to open and close circuits to control the flow of electricity.
Ch 12.2 Waves in Motion ppt
The document discusses two types of waves - transverse waves where the oscillations are perpendicular to the direction of motion and longitudinal waves where the oscillations are parallel. It covers wave characteristics like frequency, amplitude and wavelength and how waves interact with objects through reflection, refraction, diffraction and absorption as well as interference when two waves meet. Key concepts are explained and examples are provided to illustrate wave behavior and interactions.

THE SACRIFICE HOW PRO-PALESTINE PROTESTS STUDENTS ARE SACRIFICING TO CHANGE T...
The recent surge in pro-Palestine student activism has prompted significant responses from universities, ranging from negotiations and divestment commitments to increased transparency about investments in companies supporting the war on Gaza. This activism has led to the cessation of student encampments but also highlighted the substantial sacrifices made by students, including academic disruptions and personal risks. The primary drivers of these protests are poor university administration, lack of transparency, and inadequate communication between officials and students. This study examines the profound emotional, psychological, and professional impacts on students engaged in pro-Palestine protests, focusing on Generation Z's (Gen-Z) activism dynamics. This paper explores the significant sacrifices made by these students and even the professors supporting the pro-Palestine movement, with a focus on recent global movements. Through an in-depth analysis of printed and electronic media, the study examines the impacts of these sacrifices on the academic and personal lives of those involved. The paper highlights examples from various universities, demonstrating student activism's long-term and short-term effects, including disciplinary actions, social backlash, and career implications. The researchers also explore the broader implications of student sacrifices. The findings reveal that these sacrifices are driven by a profound commitment to justice and human rights, and are influenced by the increasing availability of information, peer interactions, and personal convictions. The study also discusses the broader implications of this activism, comparing it to historical precedents and assessing its potential to influence policy and public opinion. The emotional and psychological toll on student activists is significant, but their sense of purpose and community support mitigates some of these challenges. However, the researchers call for acknowledging the broader Impact of these sacrifices on the future global movement of FreePalestine.

- 2. 1. *Support: the skeleton holds your body up and gives you shape. 2. *Protection: The skull protects the brain, vertebrae protect the spinal column, rib cage protects the heart, lungs, and other organs.
- 3. 3. *Movement: Bones are attached to muscles to help your body move. 4. *Formation of blood cells: Red bone marrow produces red blood cells, white blood cells and platelets. 5. *Storage: bones store minerals such as calcium and phosphorus
- 4. * There are 206 Bones in an adult skeleton. These are divided into two types: The Axial Skeleton includes the skull, vertebral column, the ribs, and the sternum. The Appendicular: the shoulders, arms, hands, hips, legs, feet (pg 941)
- 6. *Cartilage- tissue that is tough but flexible Examples: End of the nose; Ears
- 7. *The membrane covering the bone is the periosteum. This membrane brings nutrients to the bone. *The outer layer of all bones is composed of Compact Bone. *Compact Bone is dense and strong; it provides strength and protection. A network of tubes runs Through the compact bone These tubes contain blood Vessels and nerves.
- 8. *Spongy bone is found in the center of short or flat bones, and at the end of long bones. *Spongy bone varies from bone to bone.
- 9. *There are two types of Bone Marrow: *Red Bone Marrow- is active. It produces red blood cells, white blood cells and platelets. Children’s bones have more red bone marrow than adults’. Red bone marrow is found in the humerus bone of the arm, femur, sternum, ribs, vertebrae and pelvis *Yellow Bone Marrow- is inactive. It consists of stored fat. Is found in many other bones.
- 10. *A Fracture is a broken or cracked bone. *A simple fracture is when a bone breaks, but does not come out through the skin. *A compound fracture is when a bone breaks and the bone protrudes through the skin. *A stress fracture is a thin crack in the bone.
- 11. Upon injury, endorphins blood the brain to reduce the amount of paint felt. (this is temporary) The injured area begins to swell. A blood clot forms between the broken ends of the bone. New bone cells begin to form as a mass of cartilage. After a few weeks, the callus made of spongy bone begins to surround the fracture. Then the spongy bone begins to be replaced by compact bone. *Calcium, age, nutrition, location and severity are all factors in how long a bone repair will take.
