The skeletal system has 5 main functions: providing shape, support, protection, assisting with movement, and producing blood cells. It is composed of 206 bones that make up the axial and appendicular skeleton. The axial skeleton includes the skull, vertebral column, and thoracic cage, while the appendicular includes the upper and lower limbs. The bones of the skeletal system come in different shapes and serve important structural and protective roles for the body.
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.
The skeletal system works as a support structure for your body. It gives the body its shape, allows movement, makes blood cells, provides protection for organs and stores minerals.
Anatomy unit 5 skeletal and muscular systems bone types and compositionrozeka01
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.
The musculoskeletal system provides structure, movement, and protection to the human body. It is composed of bones, cartilage, tendons, ligaments, joints, and muscles. Bones provide structure and store minerals, muscles allow movement by contracting and relaxing, and joints connect bones to facilitate motion. Together, these components form a complex system that is essential for human movement and survival.
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.
The skeletal system is composed of 206 bones that serve important biological and mechanical functions. The axial skeleton includes 80 bones that form the axis of the body and protect organs like the brain, while the appendicular skeleton has 126 bones that make up the limbs and their attachments. Bones are living organs composed of compact and spongy tissues, cells like osteoblasts and osteoclasts, and minerals including calcium that provide structure and strength. The skeleton supports the body, protects organs, allows for movement through leverage, and stores minerals and produces blood cells in the bone marrow. Bones are classified by their shapes including tubular, flat, irregular, and sesamoid.
The document provides information about the musculoskeletal system, including bones, joints, muscles, ligaments, and tendons. It discusses the 206 bones in the human body, which are divided into the axial skeleton and appendicular skeleton. There are two types of bone tissue - compact bone and spongy bone.

This document provides an overview of bone tissue and the skeletal system. It discusses the key functions of bone, the major tissues of the skeletal system including bone, cartilage, periosteum and endosteum. It describes the structure of long bones and the histology of compact and spongy bone. Bone formation occurs through two processes, intramembranous and endochondral ossification. Bone growth and remodeling requires balanced activity of osteoblasts and osteoclasts and is regulated by minerals, vitamins and hormones like PTH, calcitonin, growth hormone and sex hormones. Calcium homeostasis in the body is maintained through hormonal control of calcium levels in the blood and bone.
There are four main types of bones: long bones, short bones, flat bones, and irregular bones. Long bones have a shaft and two articulating ends, examples being the femur and humerus. Short bones are cube-shaped like wrist and ankle bones. Flat bones are broad and thin, found in the skull, shoulder blades, ribs, and sternum. Irregular bones come in various shapes and sizes, like the patella. Bones are made up of cells, fibers, and extracellular matrix. They provide structure, protection, movement, mineral storage, and blood cell formation to the body. Bone formation occurs through two processes - intramembranous ossification which forms flat bones, and endochondral oss
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.
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.
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.
The skeletal system provides structure and protection for the body. It is made of bones connected by ligaments at joints, and bone marrow inside bones produces blood cells. The skeleton changes over one's lifetime from a flexible newborn skeleton with over 300 bones to the 206 bone adult skeleton. Bones are constantly being built and repaired by osteoblasts and osteoclasts throughout life.
The skeleton serves three main functions: support, protection, and assisting in movement. It supports the body and provides attachment points for muscles. Bones protect internal organs like the brain, spinal cord, heart and lungs. When muscles contract, they cause bones to move. The skeleton also stores minerals, produces blood cells in bone marrow, and stores chemical energy. The skeleton is divided into the axial skeleton consisting of bones in the head, neck and trunk, and the appendicular skeleton consisting of the limbs and their attachments. Bone is a living connective tissue that can repair itself and has three layers: periosteum, compact bone and cancellous bone with marrow inside. Cartilage is also discussed along with joints and common skeletal disorders.
The skeletal system is composed of bones and associated tissues that provide structure, protection, movement, and mineral storage. Bones are living tissues composed of cells, collagen fibers, and minerals. There are four types of bones - long, short, flat, and irregular - with different structures adapted to their functions. Bones develop through intramembranous or endochondral ossification and are remodeled throughout life by bone cells.

The musculoskeletal system provides structure, protection, movement, and locomotion for the body. It includes bones, cartilage, tendons, ligaments, and muscles. The skeletal system functions as a framework, protects internal organs, contains bone marrow, and stores minerals and fat. Bones come in different shapes and sizes and connect to form the axial and appendicular skeleton. Bone tissue includes compact and spongy bone, and bone cells include osteoblasts, osteocytes, and osteoclasts that form and remodel bone. Joints allow bones to articulate and include immovable, slightly movable, and freely movable joints. Common disorders of the skeletal system include osteoporosis, rickets/osteomalacia, arthritis, fractures
The skeletal system has several functions including support, protection, movement, mineral storage, and blood cell formation. The skeleton is made up of bones and cartilage, with 206 bones in the adult human. Bones are living tissue made up of cells, protein fibers, and mineral deposits. They develop through ossification and are remodeled throughout life. Joints connect bones and allow movement, with different types including immovable, slightly movable, and freely movable joints. Injuries can damage bones and joints.
The skeletal system provides structure and protection to the body. It maintains the body's shape and allows for movement through joints and leverage of muscles. The skeletal system also stores minerals and produces blood cells. Bones are composed of compact bone and spongy bone, and are continually remodeled through the actions of osteoblasts, osteocytes, and osteoclasts.
Bone is a composite material made up of cells and an extracellular matrix. At the micro level, bone contains osteoblasts that build bone tissue, osteoclasts that resorb bone, and osteocytes embedded in the matrix. The matrix is made of collagen fibers mineralized with hydroxyapatite crystals. Bones can be classified by their macro structure as long, short, flat, or irregular. Long bones have a diaphysis and epiphyses. Bone structure is adapted to its mechanical functions according to Wolff's law.
The document discusses the musculoskeletal system and provides an overview of bone structure and classification. It identifies the main functions of bones as support, protection, movement, storage of minerals/fats, and blood cell formation. Bones are classified based on location in the body, shape, and internal structure as either compact or spongy bone.
This document summarizes the human skeletal system. It discusses that the skeletal system has four main functions: protecting organs, producing blood cells, providing structure, and enabling movement. It then lists the 206 bones in the human body, categorizing them into long bones, short bones, flat bones, and irregular bones. The document describes the three types of connective tissue - cartilage, ligaments, and tendons - that support joints. It explains the three classifications of joints - fixed, slightly movable, and synovial freely movable joints. Injuries like sprains, fractures, scoliosis, and kyphosis are also summarized.
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.
Osteology is the study of bones. Bones provide structure, protection, movement, mineral storage, blood cell formation, and energy storage. Bone tissue consists of cells within an organic collagen-rich extracellular matrix as well as an inorganic mineral component. Cortical bone forms the dense outer layer of long bones and has concentric osteons. Cancellous or spongy bone is found at the ends of long bones and in flat and irregular bones. Bones experience both compression and tension forces and have adapted structures like osteons and layered lamellae to withstand these stresses.
The document discusses the structure and function of long bones. It describes the key parts of long bones including the diaphysis, epiphyses, articular cartilage, periosteum, medullary cavity, compact and spongy bone. It also discusses bone formation through intramembranous and endochondral ossification as well as homeostasis and functions of bone such as support, protection, movement, blood cell formation, and storage of inorganic salts.
The musculoskeletal system comprises the bones, muscles, cartilage, tendons and ligaments in the body. It provides form, support and movement. The muscular system includes voluntary and involuntary muscles that enable movement and maintain posture. The skeletal system comprises bones and joints, including 206 bones that make up the framework of the body. Bones are classified as flat, irregular, long or short. Joints include fibrous, cartilaginous and synovial joints like the ball and socket hip joint that allow movement. Together the musculoskeletal system provides structure, movement and protection to the body.

How to produce a good science fair displayJavier Aguirre
This document provides guidance on creating an effective science fair display. It recommends including sections like the research question, hypothesis, materials, procedure, results, conclusions, and recommendations. The display should tell the story of the project clearly and attractively using a limited color palette, well-organized headings, and balanced visual elements like models, photos, and charts. Safety is important, so hazardous materials like chemicals or living organisms are not permitted.
The circulatory system transports nutrients, oxygen, and hormones throughout the body and removes wastes. It includes the heart, blood, and three types of blood vessels - arteries, veins, and capillaries. The heart pumps blood through the vessels. Arteries carry blood away from the heart to capillaries, where nutrients and gases are exchanged with body tissues. Then veins carry blood back to the heart with waste products. This continuous circulation allows for transport and exchange of materials throughout the body.
The document discusses the flipped classroom model of education. In a flipped classroom, instructional content is delivered to students outside of class, often through online videos, freeing up class time for more active and collaborative learning activities. During class, teachers guide students through hands-on problem solving, discussions, experiments and other engaging lessons, allowing for more personalized attention. The flipped classroom shifts the focus from a teacher-centered model to a learner-centered approach that emphasizes higher-order thinking skills.
The document discusses gene regulation and expression in prokaryotes and eukaryotes. In prokaryotes like bacteria, genes are organized into operons and regulated by DNA-binding proteins that control transcription. The lac operon in E. coli regulates genes needed to break down lactose and is turned on or off by the lac repressor binding in the presence or absence of lactose. In eukaryotes, gene expression is more complex and regulated by transcription factors binding regulatory regions and controlling transcription. RNA interference is another mechanism where small RNAs regulate genes by interfering with mRNA. Master control genes regulate development by controlling gene expression and cell differentiation.
The document summarizes the anatomy and function of the heart and circulatory system. It describes the pulmonary and systemic circuits that carry blood between the heart and lungs and between the heart and body. It explains how the heart pumps blood through the atria and ventricles, regulated by the pacemaker and electrical signals. It defines systolic and diastolic blood pressure measurements in terms of artery wall pressure during ventricle contraction and relaxation.
The skeletal system is made up of bones, ligaments, and tendons. It provides structure and support to the body, protects internal organs, and allows for movement. The skeletal system is divided into the axial skeleton which includes the skull and vertebral column, and the appendicular skeleton which includes the upper and lower limbs. Bones have several functions including mineral storage, protection, movement, and blood cell production. There are different types of bones including long bones like the femur, flat bones like the ribs, and short or irregular bones. Joints can be fibrous, cartilaginous, or synovial, and allow different degrees of movement between bones.
The skeletal system consists of 206 bones that make up the axial skeleton (skull, vertebral column, rib cage) and appendicular skeleton (bones of arms, legs, pelvis, shoulder). Bones provide structure, protect organs, allow movement, store minerals, and form blood cells. Typical long bones have outer compact bone, inner spongy bone, and bone marrow. Cartilage develops into bone through ossification before and after birth. Joints like the knee connect bones and allow movement through ligaments, synovial fluid, and other structures. Common bone and joint issues include fractures, ligament tears, inflammation, arthritis, and osteoporosis.
Cartilage and bone are connective tissues that provide structure and support. There are three types of cartilage - hyaline, fibro, and elastic - each with different compositions and locations in the body. Bones contain bone tissue as well as other tissues. Bones function to provide structure, protect organs, allow movement via muscle attachment, produce blood cells, and store minerals and energy. There are four classes of bones - long, short, flat, and irregular - with different shapes and locations. Bones grow and remodel through both interstitial and appositional growth.
Bones provide structure, protect organs, and enable movement. The human skeleton contains 206-213 bones including long bones in the limbs, flat bones in the skull, and irregular bones in the spine. Bones are living tissues composed of compact bone and spongy bone. Bone marrow inside bones produces red blood cells, white blood cells, and platelets. In addition to structure and movement, bones also support metabolism, blood cell production, immunity, and brain function.
The musculoskeletal system provides movement, stability, and support to the body. It consists of two main systems - the skeletal system and the muscular system. The skeletal system includes all bones and joints, with 206 total bones that are classified based on their shape into long, short, flat, irregular, and sesamoid bones. The muscular system contains over 600 muscles that are attached to bones via tendons. When muscles contract, they pull bones to create movement. There are three main types of muscles - skeletal, smooth, and cardiac muscle.
The skeletal system consists of bones, cartilage, and joints that work together to support the body, protect organs, allow movement, store minerals, and produce blood cells. There are four classes of bones - long bones in the arms and legs, short bones in the hands and feet, flat bones that make up the skull and ribs, and irregularly shaped bones. Joints connect bones and allow movement. Maintaining bone health requires weight-bearing exercise, adequate vitamin D and calcium intake, and avoiding risk factors like smoking.
The skeletal system is composed of bones and connective tissues that provide structure, support, protection, movement, and mineral storage. There are four main bone types - long bones in the limbs, short bones in the wrists and ankles, flat bones in the skull and trunk, and irregular bones like the vertebrae. Bones have external features like ridges and internal structures like compact and spongy bone. The spinal column consists of 33 vertebrae that are specialized in different regions and enable movement while protecting the spinal cord.
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.

The skeletal system is made up of bones, joints, and connective tissues. It provides structure, support, and protection to the body. Bones come in two types - compact and spongy. They have structures like periosteum, Haversian canals, and contain cells like osteoblasts. Joints allow movement and include ligaments, tendons, cartilage, and fluid-filled sacs. Common diseases are osteoarthritis, osteoporosis, and bone tumors. Osteoarthritis causes joint pain and stiffness. Osteoporosis increases fracture risk. Bone tumors can be benign or cancerous and cause pain. Treatment depends on the condition and may include exercise, medication, or surgery.
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.
A thorough understanding of the bones that make up the skeletal system, the differences between a joint, tendon and a ligament and the effect of physical activity on the human skeleton.
Skeletal System and the impact of physical activity by Ronella Romero nellz10186
The document discusses the human skeletal system, including that it is made up of bones, cartilages, tendons and ligaments. It provides details on the composition of bones, the different types of bones including long bones, short bones, flat bones and irregular bones. Additionally, it examines joints, tendons, ligaments and the long term effects of physical activity on the skeletal system.
This document provides an in-depth overview of the skeletal and muscular systems as they relate to analyzing human movement and developing conditioning programs for athletes. It examines the structure and functions of the skeletal system including bones, joints, and growth. It also explores the structure of synovial joints and the various movements they allow. The goal is to explain these systems and how knowledge of them can be applied to analyzing muscle actions and developing training programs.
This document provides an overview of the skeletal system, including its classification, anatomy, functions, and related diseases. The skeletal system consists of both the axial skeleton (skull, vertebral column, ribcage) and appendicular skeleton (limbs). Bones provide structure, allow movement through joints, protect organs, produce blood cells in the bone marrow, and store minerals. Diseases like osteoporosis and arthritis affect the skeleton and its functions.
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.
The document provides an overview of the human skeletal system, including:
- The 206 bones in the adult body and their main functions of providing structure, protecting organs, and allowing muscle movement.
- Key bones like the skull, spine, ribs, arms, legs, hands and feet.
- The composition of bones from calcium, cells and collagen.

Using QR Codes in the EFL classroom to motivate readingJavier Aguirre
Digital tools can be used in the EFL classroom in two main ways: as teaching resources and to enhance learning experiences. As teaching resources, technology includes things like chalkboards, videos, and digital resources on the internet. Technology can also enhance learning by providing students greater exposure to the target language outside of class times. One specific digital tool discussed is using QR codes for a reading race, which can add interest and motivation for students compared to only using paper texts. It works best if students have smartphones and there is a WiFi connection. Examples showed students actively engaged in a QR code reading activity in the English language classroom.
This lesson plan is for a 7th grade English class about Hollywood stunts. The plan outlines warm-up, pre-reading, reading, and post-reading activities. Students will watch a video on stunts, discuss movies with stunts, and look at textbook pictures. They will then read a text in sections using QR codes and reconstruct paragraphs. After further reading, students will discuss the text and put pictures in order. Finally, students will have conversations about whether actors should do their own stunts.
The document discusses human genetics and inheritance patterns. It covers topics like human chromosomes, genetic disorders, studying the human genome, and inheritance of traits. Key points include that humans have 23 pairs of chromosomes, including one pair of sex chromosomes (X and Y); genetic disorders can be caused by changes in chromosomes or DNA; and traits can be inherited in sex-linked patterns when located on the X or Y chromosome.
The document summarizes techniques used to study the human genome such as using restriction enzymes to cut DNA into fragments, gel electrophoresis to separate fragments by size, and DNA sequencing to read base pairs. It discusses the goals of the Human Genome Project including sequencing all human DNA and identifying genes. The project found the human genome contains 3 billion base pairs with only 2% encoding proteins. It also identified over 3 million single base differences between individuals and associated gene sequences with diseases.
Genetic disorders can be caused by changes in individual genes or chromosomes. Changes in a gene's DNA sequence can alter proteins and affect phenotypes. Sickle cell disease is caused by a defective allele that makes hemoglobin less soluble, causing red blood cells to take on a sickle shape. Cystic fibrosis is usually caused by the deletion of three DNA bases, causing a protein to fold improperly and preventing chloride transport. Huntington's disease involves a dominant allele with an abnormal number of repeats of the codon CAG, coding for glutamine. Chromosomal disorders can result from errors in meiosis like nondisjunction, leading to an abnormal number of chromosomes and conditions like Down syndrome, Turner syndrome, or Klinefelter syndrome.
A karyotype shows the complete set of chromosomes arranged in pairs by size. Studying karyotypes is important for understanding human genetics. Humans have 46 chromosomes, including two sex chromosomes that determine sex (XY for males and XX for females). The other 44 chromosomes are called autosomes. Many human traits are inherited according to patterns of simple dominance, codominance, or sex-linked inheritance. Pedigree analysis can be used to determine the inheritance patterns of traits within families.
Mutations are changes in genetic information that can be inherited. There are two main types: gene mutations which affect a single gene, and chromosomal mutations which involve changes to whole chromosomes. Gene mutations include point mutations like substitutions, insertions, and deletions. Chromosomal mutations involve changes in chromosome number or structure like deletions, duplications, inversions, and translocations. The effects of mutations vary - some have no effect, some are harmful by disrupting gene function, and some can be beneficial by producing variation that helps organisms adapt to changing environments.
1) Ribosomes use the sequence of codons in mRNA to assemble amino acids into polypeptide chains through the process of translation.
2) Messenger RNA carries codons that are read by ribosomes to direct the binding of transfer RNA molecules and the addition of amino acids to form a polypeptide chain.
3) The central dogma of molecular biology is that genetic information flows from DNA to RNA to protein, with DNA containing the genetic instructions and proteins performing most functions in cells.
RNA plays an important role in decoding the genetic instructions contained in DNA and directing protein production. There are three main types of RNA - messenger RNA (mRNA), which carries copies of gene instructions from DNA to the ribosomes, ribosomal RNA (rRNA), which makes up part of the ribosomes, and transfer RNA (tRNA), which transfers amino acids to the ribosomes during protein production according to the mRNA instructions. RNA is produced from DNA in a process called transcription, in which RNA polymerase uses a DNA strand as a template to make a complementary RNA molecule.
This document provides an introduction and instructions for a research project on periods of British literature. Students will work in pairs to research one of several literary periods, finding a timeline of important events, describing life during the period and philosophical/social beliefs, identifying major authors and an important work by each, researching a prominent writer, and creating a presentation and written report to share their findings with the class. Students are expected to consult multiple sources and include citations in their work.
Timeline and Characteristics of British LiteratureJavier Aguirre
This document provides an overview of the major periods and characteristics of British literature from Old English/Anglo-Saxon period through the modern period. It discusses the key historical contexts, genres, styles, effects and samples of influential authors for each period. The periods covered include Old English, Middle English, Renaissance, Neoclassical, Romantic, Victorian and Modern.
This document provides an analysis of Shakespeare's Sonnet 130 "My mistress' eyes are nothing like the sun". It begins by noting that the sonnet follows the classical English sonnet rhyme scheme of abab cdcd efef gg and is written in iambic pentameter. It then discusses how the sonnet subverts the tradition of Elizabethan poets using extravagant imagery to praise the beauty of their beloveds. While seeming unflattering, the poem actually gets ahead of other poets in its sincere yet playful manner of praising his lady. The tone is different than Sonnet 18 but still has a serious point beneath its playfulness. The ending couplet is powerful enough to potentially placate the mysterious dark
This document provides an analysis of Shakespeare's Sonnet 18. It begins with the full text of the sonnet. It then provides context that a sonnet is a 14-line poem typically following a rhyme scheme of abab cdcd efef gg. It defines terms like iambic pentameter, foot, and meter. The sonnet compares the subject's beauty to a summer's day, saying their beauty is more enduring and will not fade with time.
This document provides a timeline of English monarchs from the Saxon period to present day. It lists the monarchs from the House of Wessex, Danish period, Saxons, Normans, Plantagenets, House of Lancaster, House of York, Tudors, Stuarts, Commonwealth, Stuart restoration, House of Hanover, Saxe-Coburg-Gotha, and Windsor royal houses. The timeline spans from 802 AD to the current reign of Queen Elizabeth II and shows the years each monarch reigned.
Cardiovascular disease is the leading cause of death in the United States. It refers to conditions affecting the heart and blood vessels, such as atherosclerosis, arteriosclerosis, and hypertension. Atherosclerosis is a narrowing of the arteries due to plaque buildup, which can lead to heart attack if a blood clot forms. Lifestyle changes like quitting smoking, exercising, and following a low-fat diet can help prevent cardiovascular disease.
This document provides information about Gregor Mendel and his experiments with pea plants that formed the basis of genetics. It discusses key terms like genotype, phenotype, dominant and recessive traits. It explains how Mendel used controlled breeding experiments and statistical analysis to discover that traits are passed from parents to offspring through discrete units (now known as genes) that segregate and assort independently. It also explains how his findings differed from and eventually replaced the earlier blending hypothesis of heredity.
The document provides information about photosynthesis including:
1. Photosynthesis takes place in chloroplasts located in plant leaves. The light reactions occur in the thylakoid membranes and produce ATP and NADPH.
2. The Calvin cycle uses the products of the light reactions along with CO2 to produce G3P, which can then be converted into glucose and other organic molecules.
3. The two main stages, the light reactions and Calvin cycle, work together to ultimately convert sunlight, water and CO2 into oxygen and energy-rich organic compounds through the overall process of photosynthesis.

2. The skeleton functions in support and movement Vocabulary Vertebra Cartilage Marrow Joint Ligament Arhtritis Osteorporosis
3. Definitions Vertebra: Segment of the backbone; encloses and protects the nerve cord. Cartilage: Type of connective tissue softer than bone. Marrow: Specialized tissue found in bone; yellow bone marrow consists of stored fat that serves as an energy reserve; red bone marrow makes cells that develop into blood cells. Joint: Area where one bone meets another. Ligament: Strong fibrous connective tissue that holds together the bones in movable joints. Arthritis: Group of skeletal disorders characterized by inflamed joints. Osteoporosis: Disorder in which bones become thinner, more porous, and more easily broken.
4. Anatomy of the Skeleton The skeleton provides a strong framework that holds your body up and maintains its shape. The skeleton also protects soft organs and provides attachment sites for your muscles. The human skeleton consists of 206 bones.
5. Bones as Living Organisms Your bones are organs made up of living connective tissue. Within this very dense connective tissue, a material known asbone matrix surrounds the bone cells. Bone matrix consists of flexible fibers of the protein collagen and a hard mineral made of calcium and phosphate. The collagen keeps the bone flexible and non-brittle, while the hard mineral helps the bone withstand forces that push on it. A sheet of fibrous connective tissue covers most of the outside surface of the bone . In addition to covering the ends of bones, cartilage is found in the tip of your nose and the outer portion of your ears. When you were a newborn, much of your skeleton was made up of cartilage. As you grew, this cartilage was gradually replaced by bone as minerals circulating in the blood accumulated in the developing bone. Bones continue to grow in length in women until about age 18, and in men until about age 21. Many bones contain specialized tissues called marrow. The shafts of long bones, such as the arm bone (humerus), have a central cavity containing yellow bone marrow. Yellow bone marrow consists of stored fat and serves as an energy reserve for the body.
6. How joints work An area where one bone meets another bone is called a joint. Some joints connect bones in a way that allows little or no movement. Such joints are called immovable joints. By being unable to move, these bones better protect the soft organs that lie beneath them. Yet, if all your bones were fused together in one continuous skeleton, you would not be able to move. Movable joints allow you to bend, twist, and rotate your limbs, neck, and torso. The bones in a movable joint are held together by a strong, fibrous connective tissue called a ligament. Movable joints can be classified by the way in which the bones come together. The different structures of the joints allow your body to move in a variety of ways.
7. Skeletal Disorders Since bones consist of living tissue, they can repair themselves by building new tissue. If properly set using a cast or splint, a bone will usually return to its normal shape and strength. Besides fractures, bones and joints can be affected by disorders of the skeletal system. Arthritis refers to a group of skeletal disorders that involve inflammation of the joints. One out of every three adults in the United States suffers from arthritis or a related joint disorder. Osteoporosis is a disorder in which bones become thinner, more porous, and more easily broken.
