Joints of human body
Joints connect bones and allow movement. There are three types of joints classified by movement: synarthrosis (immovable), amphiarthrosis (slightly movable), and diarthrosis (freely movable). Joints can also be classified structurally as fibrous, cartilaginous, or synovial. Synovial joints are found at the shoulder, elbow, wrist, hip, knee, and ankle and contain synovial fluid that reduces friction and nourishes cartilage.
Day 3
Cartilage is a connective tissue found in joints between bones. It is made up of cells called chondrocytes that produce collagen, proteoglycans, and elastin. There are no blood vessels in cartilage, so it repairs and grows slowly. Tendons connect muscle to bone and are made of collagen, while ligaments connect bones to other bones. Joints are points where bones connect, allowing movement, and can be classified by the tissue present and degree of movement. Common joint disorders include dislocations, sprains, bursitis, and various forms of arthritis.
Joints I
This document describes several types of joints in the body:
- Sutures are fibrous joints between skull bones that have interlocking edges.
- Syndesmoses are ligament joints with longer fibrous tissue than sutures, such as between the fibula and tibia.
- Gomphoses are "peg in socket" fibrous joints like the tooth in the jaw.
- Synchondroses and symphyses unite bones with cartilage, such as between vertebrae and the pubic bones.
Joints II
This document provides an overview of several synovial joints in the body - the knee, shoulder, elbow, hip, and temporomandibular joint. For each joint, it describes the structural features, types of motions allowed, and major ligaments involved. It also discusses common joint injuries like tears and sprains, as well as inflammatory and degenerative conditions like bursitis, tendonitis, osteoarthritis, rheumatoid arthritis, gout, and Lyme disease. Developmental aspects are also covered, noting how joints change with use and age.
cartilage structure and function
Cartilage is a firm but flexible connective tissue found in many areas of the body, including joints, ribs, spine, ears and nose. There are three main types of cartilage - hyaline, fibrocartilage, and elastic. Hyaline cartilage is the most common and is found at bone joints and in embryonic skeletons. It provides smooth surfaces and flexibility. Fibrocartilage is strong and found in joints like the meniscus. Elastic cartilage is yellow and found in ears and the epiglottis, providing shape and support to these structures.
Cartilage and joints
Cartilage is a type of connective tissue found in joints that provides structure and elasticity. There are three main types of cartilage - hyaline, elastic, and fibrocartilage. Joints allow bones to articulate and move. The two main types are diarthrodial synovial joints, which have a joint cavity and allow free movement, and synarthrodial joints, which are solid joints with little to no movement. Common synovial joints include hinge joints, pivot joints, condyloid joints, saddle joints, and ball and socket joints. Cartilage, synovial fluid, menisci, and other structures work together to provide support, lubrication, and smooth movement between bones.
Tendons
This document summarizes key information about tendons. Tendons transmit force from muscles to bones, allowing joint movement. They are composed primarily of collagen and are very strong, withstanding mechanical forces. Tendons can be paratenon covered or sheathed. Paratenon covered tendons like the patellar and Achilles tendons have good blood supply and heal well. Sheathed tendons like in the hand have less blood flow. Tendon composition is mostly collagen types I and III, along with water, proteoglycans, and minerals. Tendons are arranged in a hierarchical structure from microfibrils to fascicles. Tenocytes are tendon cells that secrete collagen. Exercise strengthens tendons while immobilization
Cartilage and bone
This document summarizes slides from cartilage and bone labs examining different types of cartilage and bone under the microscope. It describes the key characteristics of hyaline cartilage, elastic cartilage, and fibrocartilage, including their matrix composition and distribution of chondrocytes. For bone, it outlines the microscopic features of compact bone, cancellous bone, intramembranous ossification, and endochondral ossification, focusing on the presence of Haversian systems, bone trabeculae, ossification centers, and the epiphyseal plate zones.

Cartilage
Cartilage functions to support the body, provide a framework for attachment of muscles, protect underlying tissues, and provide flexibility. There are three main types of cartilage - hyaline, elastic, and fibrous - which differ in their fiber composition and density. Hyaline cartilage is the most common and found at joints, nose, trachea, and fetal skeleton. Elastic cartilage is rare but found in ear and epiglottis where its elasticity is important. Fibrous cartilage has strong collagen fibers and acts as a shock absorber in joints, discs, and meniscus.
Connective tissue
The document discusses several types of connective tissues: ligaments, tendons, and bursae. Ligaments connect bones at joints and allow movement while preventing abnormal motions. Tendons connect muscles to bones and transmit forces from muscles. Bursae are fluid-filled sacs that provide cushioning between bones, tendons, and muscles around joints. Common conditions that can affect these tissues include sprains of ligaments from overstretching and tendinopathies or tendon injuries from overuse.

The document discusses how cancer treatments can damage bone marrow and prevent blood cell production, how osteoporosis weakens bones by inhibiting calcium's role in bone growth, and how epiphyseal plate fractures are more common in children and young adults as the plates at the ends of long bones are still hardening during growth. Proper nutrition is also highlighted as important for maintaining strong bones in adults.
Fascia
Fascia is a connective tissue that forms a three-dimensional net throughout the body. It is composed of collagen fibers, fibroblasts, and ground substance. Fascia exists in layers - superficial fascia beneath the skin aids with insulation and cushioning, while deep fascia separates and surrounds muscles. Fascia is avascular but contains myofibroblasts that allow it to exert contractile forces. It transmits tension throughout the body to allow upright posture and movement through myofascial lines and trains. Maintaining proper hydration is important for collagen structure and fascial function. Myofascial release techniques can help improve fascia mobility and reduce pain.

The document summarizes three key components of bone structure:
1. Periosteum is the membrane lining the outer surface of bones (except at joints) and consists of fibrous and osteogenic layers, providing nourishment and attachment points for muscles and tendons. It contains cells that form new bone after fractures.
2. Endosteum is the delicate lining of marrow spaces and cavities, consisting of a single layer of cells. It has osteogenic potential and can form new bone with stimulation.
3. Haversian systems are the structural units of compact bone.
Tendons ligaments
Tendons consist of parallel bundles of collagen fibers that provide great tensile strength to anchor muscles to bones. Ligaments contain bundles of elastic fibers and some collagen, making them more flexible than tendons but offering less strength to hold bones together. Fibroblasts secrete the fibers and ground substance of connective tissue and are called fibrocytes when not actively engaged in synthesis. The poor blood supply to tendons and ligaments affects their behavior in the body.
CARTILAGE STRUCTURE AND ITS FUNCTION
Cartilage is a connective tissue found in many areas of the body including joints, ribs, spine, ears and nose. There are three main types of cartilage - hyaline, fibrocartilage, and elastic cartilage. Hyaline cartilage is the most abundant and found covering bone surfaces in joints. It contains chondrocytes and provides smooth, flexible surfaces for movement. Fibrocartilage is strong and found in intervertebral discs, menisci, and healing fractures. It contains collagen fibers. Elastic cartilage is yellow and found in external ears and epiglottis. It contains an elastic fiber network and maintains the shape of structures.

Joints are where two or more bones meet, though movement does not always occur. Structurally, joints are classified as fibrous, cartilaginous, or synovial. Synovial joints are freely movable and contain synovial fluid within an articular capsule. The six types of synovial joints are hinge, pivot, ball-and-socket, saddle, condylar, and gliding joints, each enabling different ranges of motion.
Cartilage and bone capture
Cartilage and bone are types of specialized connective tissue that originate from mesoderm. The main difference is that cartilage is avascular while bone is vascularized. Cartilage contains factors that prevent invasion by blood vessels. Cartilage is composed of chondrocytes suspended in an extracellular matrix, while bone contains osteoblasts, osteocytes, and osteoclasts involved in formation and resorption of bone tissue.
Articulations
There are two main ways to classify joints in the human body. Structural classification divides joints into three categories - fibrous, cartilaginous, and synovial - based on how the bones connect and whether a space exists between them. Functional classification also has three categories - synarthrosis, amphiarthrosis, and diarthrosis - and considers the degree of movement permitted at each joint. Synovial joints allow the most movement as diarthrosis joints, while fibrous joints permit the least movement and are mostly synarthrosis joints.

Bones and cartilage
This document discusses bones, cartilages, and joints. It describes the composition, types and functions of bones, including long bones, flat bones, and irregular bones. It examines bone cells, formation, and healing. The document also details the types of cartilage, including hyaline, elastic, and fibrocartilage. Additionally, it outlines the different types of joints that restrict movement, allow movement, and names some joint abnormalities.
Cartilages and bones
This document summarizes skeletogenic connective tissues, including cartilages and bones. It describes the different types of cartilage, including hyaline, elastic, and fibrocartilage. Hyaline cartilage is the most common and found in many areas including joints. Cartilage is avascular and receives nutrients through diffusion. Cartilage contains chondrocytes that secrete the extracellular matrix. Bones are composed of bone tissue, periosteum, endosteum, and bone marrow. Bones develop through either intramembranous or endochondral ossification and are remodeled throughout life by osteoblasts, osteocytes, and osteoclasts.
Cartilage & bones
Cartilage and bone are types of connective tissue that provide structure and support. There are three main types of cartilage - hyaline, elastic, and fibrocartilage - which are located in various parts of the body like joints, ears, and larynx. Cartilage is made of chondrocytes in an extracellular matrix. Bone develops from cartilage through endochondral ossification and forms directly from mesenchymal tissue through intramembranous ossification. Bones have compact bone, spongy bone, and are remodeled through the actions of osteoblasts and osteoclasts. Common bone disorders occur due to defects in collagen, calcification, or excessive bone turnover.
The Musculoskeletal system
The document discusses the musculoskeletal system, including bones, joints, muscles, tendons, and ligaments. It describes how bones are composed of compact and spongy bone and how ossification occurs over 20 years. There are 206 bones that are classified as long, flat, or irregular. Bones provide structure, protection, and sites for muscle attachment. Joints, such as hinges, gliding joints, ball-and-socket joints, and pivots, connect bones and allow movement. Joints are held together by ligaments and cartilage while tendons connect muscles to bones. Muscles contract and relax to flex and extend limbs through tendons at joints.
Cartilage
There are three main types of cartilage: hyaline, fibro, and elastic. Hyaline cartilage is the most common and found in places like the ribs and nose. It has fine collagen fibers that give it strength. Fibro cartilage is found in intervertebral discs and is the strongest type, with thick collagen fibers arranged to withstand stress. Elastic cartilage contains elastic fibers and is located in places requiring flexibility like the ear.
Bones and cartilages
The document discusses bones and cartilages. It describes the structure and types of cartilage, including elastic, fibrocartilage, and hyaline cartilage. It then covers the gross structure of bones, including compact and cancellous bone. Bone cells like osteoblasts, osteoclasts and osteocytes are also discussed. The functions of bone include mechanical support, mineral storage, and endocrine functions. Bone formation occurs through endochondral and intramembranous ossification. The document also outlines different types of bones such as long, short, flat, and irregular bones.
Skeletal physiology
The document discusses skeletal physiology, including the functions of bones, bone homeostasis, ossification processes, fracture repair, bone cell types, and classifications of joints. It addresses five functions of bones: support, protection, movement, mineral storage, and hematopoiesis. It describes the two types of ossification - intramembranous and endochondral - and the phases of fracture repair. Key bone cell types are identified as osteoblasts, osteoclasts, and osteocytes. Joints are classified based on both structure and function.
Classification of joints
Joints are classified structurally based on how bones connect and functionally based on degree of movement. Structural types are fibrous, cartilaginous, and synovial. Fibrous joints allow little movement, cartilaginous more than fibrous but less than synovial. Synovial joints have the most mobility and include ball-and-socket, hinge, and gliding joints. Functionally, joints are synarthrosis (no movement), amphiarthrosis (slight movement), and diarthrosis (varied movement like flexion). Key parts of joints are articular cartilage, synovial cavity, articular capsule, synovial fluid, and ligaments.

JOINTS.pptx
Joints are where two or more bones meet, and can allow for varying degrees of movement. There are three main types of joints classified by their movement: immobile, partially mobile, and freely mobile. Joints can also be classified by the number of bones that meet (simple, compound, complex) or by the type of tissue connecting the bones (fibrous, cartilaginous, synovial). The stability of a joint depends on the shape of the articulating surfaces, associated ligaments, and muscle tone. Common joint conditions like osteoarthritis and rheumatoid arthritis can lead to pain and inflammation as cartilage degenerates over time. Joint replacement prosthetics may be used to treat severe arthritis.
Fibrous joints
This document discusses the three types of joints in the body - fibrous, cartilaginous, and synovial joints. It focuses on fibrous joints, which are connections between bones held together by collagen fibers or other fibrous connective tissues, making them largely immobile. Examples of fibrous joints include sutures in the skull, syndesmoses between bones of the limbs, and gomphoses where teeth attach to alveolar sockets. While fibrous joints allow little to no movement, they provide strength and stability at sites of bone connection throughout the body.

The skeletal system consists of bones, cartilage, and joints. Cartilage is a connective tissue found in the developing embryo and is later replaced by bone. There are various types of cartilage and bones that serve different functions like support, movement, protection, and mineral storage. Joints are classified based on their structure and range of movement. The main types are fibrous, cartilaginous, and synovial joints. Synovial joints have articular cartilage, a joint cavity lined by synovium, and a joint capsule that permits the greatest range of movement like the ball and socket shoulder joint.

The document discusses the anatomy of human joints. It defines a joint as the place where bones connect. Joints are classified based on the type of connective tissue and whether a space exists between the bones. The three main types of joints are fibrous, cartilaginous, and synovial joints. Synovial joints have a fluid-filled cavity and allow the most movement. Within synovial joints, movement can be uniaxial, biaxial, or multiaxial. The six specific types of synovial joints, from least to most movable, are planar joints, hinge joints, pivot joints, condyloid joints, saddle joints, and ball-and-socket joints.

Joints are connections between bones that allow movement. The main types are fibrous joints with little movement, cartilaginous joints with some movement, and synovial joints which are freely movable. Synovial joints contain articular cartilage, a joint capsule, synovial membrane that produces fluid, and many have ligaments. The fluid lubricates and nourishes the joint. Common synovial joints include the shoulder, elbow, wrist, hip, knee, ankle, and small joints of the hands and feet. Joint pathology includes arthritis, bursitis, dislocations, and conditions like hip dysplasia. Joint fluid analysis evaluates the fluid for signs of inflammation or infection.

Joints are classified as either synarthroses (immovable joints) or diarthroses (freely movable joints). Diarthroses, also called synovial joints, are further classified based on their plane of movement, number of articulating bones, and shape of the articulating surfaces. Key features of synovial joints include the articular capsule, articular cartilage, synovial fluid, ligaments, and associated structures like menisci and bursae. The document provides detailed descriptions of these structures and their functions.
Joints structure and classification
A joint is formed where two or more bones come into contact and are attached by ligaments or cartilage. There are several types of joints including fibrous joints which have no movement, cartilaginous joints which allow limited movement, and synovial joints which are freely movable and lubricated by synovial fluid within a joint capsule. Common synovial joints include ball-and-socket joints like the shoulder, hinge joints like the knee, and gliding joints between wrist and ankle bones.
08 Articulations General Features
The document discusses different types of joints in the body, including synovial joints, cartilaginous joints, fibrous joints, and their specific examples and characteristics. It covers topics like the structure and function of joints, types of movements allowed by different joints, and clinical cases involving joint disorders.

It covers topics like the structure and function of joints, types of movements allowed by different joints, and clinical examples of joint disorders. Key points mentioned are the different structural and functional classifications of joints, examples of specific joints like the hip, shoulder, and intervertebral joints, and how joints allow movement through leverage of muscles and bones.
JOINTS
oint: The area where two bones are attached for the purpose of permitting body parts to move. A joint is usually formed of fibrous connective tissue and cartilage.
ABHI (TYPES OF JOINTS 2).docx
The skeletal system consists of bones and cartilage. Cartilage is more prevalent than bone in the developing embryo, but bone replaces cartilage during fetal and childhood development. There are various classifications of bones based on their shape. Joints are where two or more bones connect, and can be classified based on their structure and range of movement. The main types of joints are immovable fibrous joints, slightly movable cartilaginous joints, and freely movable synovial joints. Synovial joints allow more movement and are further divided into uni-axial, bi-axial, and multi-axial joints based on the axis of movement they permit.
