Joints of the human body
Joints of the human bodyJay Patel This document discusses the classification and types of joints in the human body. It begins by classifying joints based on their motion capabilities into synarthroses, amphiarthroses, and diarthroses. It then further classifies joints based on the material that joins them into fibrous, cartilaginous, and synovial joints. The document focuses on synovial joints, describing their characteristics like hyaline cartilage, joint cavity, synovial membrane, and types including hinge, pivot, condyloid, saddle, ball and socket, and plane joints. It provides examples of joints in the pectoral girdle, upper limb, pelvic girdle, and lower limb.
Joints structure and classification 
Joints structure and classification trieducation 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.
The Joints
The JointsMr. Mata Deen A joint is an articulation between two bones in the body and are broadly classified by the tissue which connects the bones. The three main types of joints are: synovial, cartilaginous and fibrous.
Fascia
FasciaDeepak Kumar 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.
Joints
JointsKemUnited Cartilage is a flexible connective tissue found in joints between bones. There are three main types of cartilage - hyaline, fibrocartilage, and elastic cartilage. Cartilage provides support, acts as a gliding surface in joints, and serves as a template for bone formation. Joints, also called articulations, are places where bones connect. The three major types of joints are fibrous, cartilaginous, and synovial joints. Synovial joints are the most common and include structures like bones, cartilage, synovial fluid, ligaments, and a joint capsule. There are different types of synovial joints based on their shape and movement capabilities, including hinge, ball-and-socket

Jointshpinn The document discusses different types of joints in the human body. There are three main types of joints: fixed or immovable joints where bones overlap and do not move; slightly movable joints where bones can move a little and are connected by ligaments and cartilage; and freely movable or synovial joints where bones move freely, including ball-and-socket joints in the hips and shoulders. The document further describes six types of synovial joints based on their movement: ball and socket, hinge, pivot, gliding, saddle, and condyloid joints. Examples are provided of each type of joint and how they enable different motions.
Classification of joints & joint mechanics
Classification of joints & joint mechanicsDr. Piyush Karn Joints are classified functionally based on their range of movement and structurally based on the intervening soft tissue. The three main types of joints are fibrous, cartilaginous, and synovial. Fibrous joints are joined by fibrous connective tissue and include sutures, gomphosis, and syndesmosis. Cartilaginous joints are joined by either hyaline or fibrocartilage and include synchondrosis and symphysis joints. Synovial joints contain a joint cavity with synovial fluid and move freely, with examples being ball-and-socket, hinge, and gliding joints. Joints function as levers, with the relationship of force points determining the lever class
Joints
JointsAarif Kanadia Joints connect bones and allow movement. There are three main types of joints - immovable joints which do not allow movement (e.g. sutures in the skull), slightly movable joints which allow some movement (e.g. symphysis pubis joint), and freely movable joints which allow extensive movement (e.g. ball and socket joint in the shoulder). Freely movable joints have structures like synovial fluid and membranes that reduce friction and allow movement. Examples of different freely movable joints are ball and socket, hinge, gliding, condyloid, saddle, and pivot joints.
Muscular System
Muscular SystemM, Michelle Jeannite The muscular system allows the body to move through muscle contraction and relaxation. There are approximately 600 muscles in the human body. Muscles are categorized as voluntary or involuntary. Voluntary muscles like those in the arms and legs can be consciously controlled, while involuntary muscles in organs cannot. The three main types of muscle are skeletal, smooth, and cardiac. Skeletal muscles move bones and are striated and voluntary. Smooth muscles are found in organs and are involuntary. Cardiac muscle is only located in the heart and is also involuntary. Muscles work in opposing pairs to enable movement, such as the biceps and triceps raising and lowering the arm.
Skeletal System 
Skeletal System Gabriella Senior The skeletal system is divided into two sections - the axial skeleton which includes the skull, vertebral column, and rib cage, and the appendicular skeleton which includes the limbs and girdles attaching them to the axial skeleton. Bones provide structure, protection, movement, mineral storage, and blood cell formation. There are 206 bones in the human body which come in four shapes - long, short, flat, and irregular. Bones are made of two types of tissue and contain three main cell types. Joints connect and allow movement between bones. The main types of joints are fibrous, cartilaginous, and synovial, with synovial joints providing the most movement.

The appendicular skeleton includes the shoulder and pelvic girdles, with the limb bones of the upper and lower limbs making up the remaining bones.
Cartilage
CartilageMichael Wrock 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.

He explains that without joints, we would not be able to move and would fall over like dominoes. There are three main types of joints - fixed, semi-movable, and movable. Movable joints like hinges, balls and sockets, and gliding joints allow for dancing by enabling movement of the arms, legs, and hips. Flaco concludes by thanking the viewer for learning about joints and invites them to a Day of the Dead dance.
Biomechanics of foot
Biomechanics of footKumarpal Singh The foot is a complex biomechanical structure that must provide both stability and mobility. It is composed of 26 bones arranged in 3 sections - the rearfoot, midfoot, and forefoot. The main joints of the foot include the subtalar, transverse tarsal, tarsometatarsal, metatarsophalangeal, and interphalangeal joints. These joints allow for pronation, supination, and a metatarsal break during gait to absorb shock and efficiently propel the body forward. The foot's unique bone structure and motion are finely tuned to support weight-bearing activities while accommodating varied surfaces.

It describes that the muscular system provides motor power for all body movements through muscle contraction. It is composed of three types of muscles - skeletal, smooth, and cardiac muscles. Skeletal muscles are voluntary and attached to bones, producing movement. Smooth muscles are involuntary and found in organs. Cardiac muscles are found only in the heart. The muscular system allows for body movements, stability, heat production, circulation, and digestion.
Classification of joints
Classification of jointsFarhan Ali 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.

Blood clotting
Blood clottingjinimohan Blood clotting is the body's defense strategy to prevent excessive blood loss from wounds. When a wound occurs, platelets and cells at the wound site produce chemical substances that synthesize the enzyme thrombin from prothrombin. Thrombin then converts soluble fibrinogen into insoluble fibrin. The fibrin forms fine filaments that trap red blood cells and platelets, creating a network that results in a blood clot that controls blood flow and seals the wound.
Types of BONES
Types of BONESAbby Mendoza The document provides information about common bones in the human body, including their English and anatomical names. It lists the skull, jaw bone, spine, breastbone, rib, collarbone, shoulder blade, thigh bone, kneecap, and shinbone. The document also discusses fractures, describing greenstick, displaced, comminuted, and impacted fractures. It notes an open or compound fracture involves a wound communicating with the break site. Treatment of fractures includes reducing the break, preventing movement with fixation methods like plates and screws, pins, or a plaster cast, to allow the fragments to unite.
Joint movements
Joint movementsMercedes_ef The document lists various joint movements including ankle rotation, knee flexion and extension, waist rotations and squats, shoulder circumduction and inclination, neck rotation and flexion/extension, wrist rotation and flexion/extension, elbow rotation and flexion/extension, shoulder rotations, hip rotation and adduction/abduction, mobilization of the trunk, and skipping with lateral movement. It focuses on different exercises that target movement in major joints throughout the body.
Blood Clotting Mechanism
Blood Clotting MechanismMujahid Hussain The document summarizes the blood clotting (coagulation) mechanism. It occurs when blood is shed from damaged blood vessels or tissues. There are two pathways - the extrinsic pathway which is initiated by tissue factor, and the intrinsic pathway initiated by platelets. Both pathways involve a cascade of coagulation factors and ultimately lead to the formation of a prothrombinase complex. This converts prothrombin to thrombin via the common pathway. Thrombin then converts fibrinogen to fibrin to form a mesh and stabilize the platelet plug, sealing the break in the blood vessel.
Blood clotting
Blood clottingSaurav Das Blood clotting is a process called coagulation where blood changes from a liquid to a solid gel-like state. It occurs through a cascade of biochemical reactions involving multiple clotting factors. Initially fibrinogen is converted to fibrin, which forms a mesh that entangles blood cells. Then the clot undergoes further changes to strengthen it. Precise regulation of coagulation prevents clotting inside healthy blood vessels but allows it to occur when vessels are damaged.
Blood clotting
Blood clottingPranaja Abel Amanta The clotting process begins when blood vessels are damaged. Platelets are released from the bloodstream and stick to the damaged tissue, where they release enzymes that trigger a chain reaction. This leads to the conversion of fibrinogen into fibrin threads, which weave together to form a blood clot that seals the break in the blood vessel. For patients with hemophilia, this clotting process does not work properly due to a genetic defect, so their blood does not clot normally and they are at risk of excessive bleeding from minor injuries. The document then describes the steps of clotting in more detail and discusses some blood clotting disorders.
Blood clotting
Blood clottingNirmala Josephine The document discusses blood clotting and the factors involved. Platelets and clotting factors work together to form blood clots which act as a mesh to stop bleeding from injuries. When a blood vessel is damaged, platelets stick to the injury site and clump together to form a platelet plug. Platelets and damaged tissue then release clotting factors which activate the blood clotting mechanism and produce fibrin to seal the wound. Impaired clotting can lead to excessive bleeding or blockages in arteries from blood clots.

Iron deficiency anemia
The most common cause of low MCH levels, this condition occurs when your body doesn't have enough iron to produce healthy red blood cells.
Microcytic anemia
A condition where red blood cells are abnormally small and carry less hemoglobin.
Thalassemia
A genetic condition that causes the body to produce less hemoglobin than normal.
Hemoglobinopathy
A condition that affects the amount of hemoglobin in red blood cells.
Low MCH levels are often treated with lifestyle changes, such as taking iron supplements or eating iron-rich foods. In some cases, blood transfusions may be required.

The most common cause of low MCH levels, this condition occurs when your body doesn't have enough iron to produce healthy red blood cells.
Microcytic anemia
A condition where red blood cells are abnormally small and carry less hemoglobin.
Thalassemia
A genetic condition that causes the body to produce less hemoglobin than normal.
Hemoglobinopathy
A condition that affects the amount of hemoglobin in red blood cells.
Low MCH levels are often treated with lifestyle changes, such as taking iron supplements or eating iron-rich foods. In some cases, blood transfusions may be required.
Low MCH levels aren't always a sign of a serious health condition. Sometimes, MCH levels can return to normal with diet changes or by avoiding alcohol.

Chapter 9Yukti Sharma Joints can be classified structurally as fibrous, cartilaginous, or synovial, and functionally as immovable, slightly movable, or freely movable. Synovial joints are the most complex and permit the greatest range of motion. They contain articular cartilage, a joint cavity lined by synovial membrane that secretes lubricating synovial fluid, and surrounding ligaments, bursae and other accessory structures. The six types of synovial joints are plane, hinge, pivot, condyloid, saddle, and ball and socket. Important examples are the shoulder, elbow, hip and knee. Range of motion and joint movements like flexion/extension are affected by various factors. Arthroplasty

Joints, function and types of joints.pptx
Joints, function and types of joints.pptx10khan113ii Joints, or articulations, are the structures where two or more bones meet, allowing for movement and providing mechanical support. They are essential for a wide range of motions and functions in the human body. Here's a detailed description of joints:
### Types of Joints Based on Structure:
1. **Fibrous Joints**:
- **Description**: Connected by dense connective tissue rich in collagen.
- **Movement**: Generally immovable (synarthrotic).
- **Examples**: Sutures in the skull, syndesmoses between long bones like the tibia and fibula.
2. **Cartilaginous Joints**:
- **Description**: Bones connected entirely by cartilage (either hyaline or fibrocartilage).
- **Movement**: Allow limited movement (amphiarthrotic).
- **Examples**: Intervertebral discs, pubic symphysis.
3. **Synovial Joints**:
- **Description**: Characterized by a fluid-filled synovial cavity that separates the articulating bones.
- **Movement**: Freely movable (diarthrotic), with various degrees and types of movement depending on the specific joint type.
- **Examples and Subtypes**:
- **Hinge Joints**: Permit flexion and extension (e.g., elbow, knee).
- **Ball-and-Socket Joints**: Allow rotational movement and a wide range of motion (e.g., shoulder, hip).
- **Pivot Joints**: Enable rotational movement around a single axis (e.g., atlantoaxial joint in the neck).
- **Gliding Joints**: Allow sliding or gliding movements (e.g., intercarpal joints in the wrist).
- **Saddle Joints**: Permit movement along two planes (e.g., thumb joint).
- **Condyloid Joints**: Allow movement but no rotation (e.g., wrist joint between the radius and carpal bones).
### Types of Joints Based on Function:
1. **Synarthroses**:
- **Description**: Immovable joints providing strong, stable connections.
- **Examples**: Skull sutures.
2. **Amphiarthroses**:
- **Description**: Slightly movable joints.
- **Examples**: Intervertebral discs, pubic symphysis.
3. **Diarthroses**:
- **Description**: Freely movable joints, synonymous with synovial joints.
- **Examples**: Most limb joints like the knee, hip, shoulder.
### Joint Anatomy:
- **Cartilage**: Covers the ends of bones, providing a smooth surface for movement and cushioning.
- **Synovial Membrane**: Lines the joint capsule and secretes synovial fluid for lubrication.
- **Ligaments**: Strong bands of connective tissue that connect bones and stabilize the joint.
- **Tendons**: Connect muscle to bone, aiding in joint movement.
- **Bursae**: Fluid-filled sacs that reduce friction between moving structures within the joint.
### Functions of Joints:
- **Movement**: Facilitate a range of bodily movements, from gross motor functions like walking and lifting to fine motor skills like writing and typing.
- **Support**: Maintain the body's structure and posture.
- **Protection**: Protect internal structures by providing cushioning and absorbing impact.
Skeleton ppt aw
Skeleton ppt awryanm9 The skeletal system has five main functions: providing shape and support, enabling movement, protecting organs, producing blood cells, and storing minerals. It is made up of bones and joints, with three types of joints - fibrous, cartilaginous, and synovial. Synovial joints allow the greatest range of movement and are found at joints like the knee. Bones and muscles are connected by ligaments and tendons, with different joint types - ball and socket, hinge, gliding, and pivot - enabling various movements like flexion, extension, and rotation. Injuries can result from overuse, incorrect movement, or impacts and twisting.

Nikku pdf on jointsNikhil Vaishnav A joint is the site where two or more bones meet. There are three main types of joints: fibrous, cartilaginous, and synovial. Synovial joints are the most common and provide the most movement. They contain synovial fluid and have articular cartilage covering the bone ends. Common synovial joints include the ball and socket shoulder joint, hinge elbow joint, pivot radioulnar joint, condyloid wrist joint, saddle thumb joint, and gliding vertebral joints.
Joints
JointsWahidahPuteriAbah Joints are where two or more bones meet. There are three main types of joints: fibrous joints which do not allow movement; cartilaginous joints which allow some movement through cartilage; and synovial joints which have the most movement ability. Synovial joints can move in flexion, extension, abduction, adduction, rotation, pronation, and supination. The major synovial joints of the upper limb are the shoulder, elbow, and wrist, while the lower limb synovial joints are the hip and knee.
BODY MOVEMENTS_Science.pptx class 6 ncert chapter 8
BODY MOVEMENTS_Science.pptx class 6 ncert chapter 8mgagan544 Human body movements are enabled by the musculoskeletal system. Muscles are attached to bones via tendons and work in pairs to contract and relax, causing movement. The main types of joints that allow movement are ball-and-socket, pivot, hinge, and gliding joints. The human skeleton consists of 206 bones divided into the axial skeleton (skull, vertebrae, ribs) and appendicular skeleton (shoulder and pelvic girdles, arms, legs). Bones are connected by joints, which can be fixed or movable, and muscles pull on bones to enable locomotion.

- 2. Introduction of Joints Joint (or articulation)- the junction between two or more bones. With the exception of the hyoid bone, every bone in the body is connected to or forms a joint. There are 230 joints in the body
- 3. Joint Functions Hold the skeletal bones together Allow the skeleton some flexibility so gross movement can occur Make bone growth possible
- 4. Joint Classification Joints are classified by: movement or tissue type Movement Immovable Slightly Movable Freely Movable Tissue (more common) 1.Fibrous 2. Cartilaginous 3. Synovial
- 5. Three General Groups of Joints Fibrous : classified by Sutures, Syndesmosis, and Gomphosis. Cartilaginous : Connected entirely by cartilage Synovial : Most common and most movable joint.
- 6. Synovial Joints Articular ends covered in hyaline cartilage and held together by dense connective tissue Joint capsules made up of ligaments (outer layer) and synovial membranes (inner layer) Some synovial joints have shock-absorbing pads called menisci and fluid filled sacs called bursae.
- 7. There are six types of synovial joints… Ball-and-Socket Joint Condyloid Joint Gliding Joint Hinge Joint Pivot Joint Saddle Joint
- 8. Ball-and-Socket Joint Ball-and-Socket Joint: consists of a bone with a ball-shaped head that attaches with the cup-shaped cavity of another bone. This type of joint allows for a wider range of motion than any other kind. It permits movement in all planes, and a rotational movement around a central axis. Two examples of this type of joint would be the hip and shoulder joints.
- 9. Condlyoid Joint Condyloid Joint: an oval-shaped condyle of one bone fits into an elliptical cavity of another bone. This type of joint permits a variety of movements in different planes. It however, does not permit rotational movement. Examples of this type of joint would be the joints between the metacarpals and the phalanges.
- 10. Gliding Joint Gliding Joint: has nearly flat or slightly curved articulating surfaces. This type of joint allows sliding and twisting movements. Some examples of this type of joint include, the joints within the wrists and the ankles, the joints between the articular processes of adjacent vertebrae, the sacroiliac joints, and the joints formed by ribs (2-7) connecting with the sternum.
- 11. Hinge Joint Hinge Joint: the convex surface of one bone fits into the concave surface of another. This type of joint permits movement in one plane only. This movement consists of flexion and extension. Two examples are the elbow and the phalanges.
- 12. Pivot Joint Pivot Joint: the cylindrical surface of one bone rotates within a ring formed of bone and ligament. Movement is limited to the rotation around a central axis. Examples of this type of joint are the joints between the proximal ends of the radius and ulna.
- 13. Saddle Joint Saddle Joint: forms between bones whose articulating surfaces have both concave and convex regions. The surface of one bone fits the complementary surface of the other bone. This type of joint permits a variety of movements. An example would be the joint between the trapezium and the metacarpal bones of the thumb.
- 14. Joint Movements Flexion: Bending parts at the joint so that the angle between them decrease and the parts come closer together Example: bending lower limb at knee Extension: Straightening parts at the joint so that the angle between them increase and the parts move farther apart Example: straightening the lower limb at the knee Extension Flexsion
- 15. Hyperextension: Excess extension of the parts at a joint beyond the anatomical position Example: bending the head back beyond the upright position Dorsiflexion: Bending the foot at the ankle toward the shin Example: bending the foot upward Plantar Flexion: Bending the foot at the ankle toward the sole Example: bending the foot downward
- 16. Abduction: Moving a part away from the midline Example: lifting the upper limb horizontally to form a right angle with the side of the body Adduction: Moving a part toward the midline Example: returning the upper limb from a horizontal position to the side of the body
- 17. Rotation: Moving a part around an axis Example: twisting the head from side to side Circumduction: Moving a part so that its end follows a circular path Example: moving the finger in a circular motion without moving the hand Supination: Turning the hand so that the palm is upward or facing anteriorly (in the anatomical position) Pronation: Turning the hand so the palm is downward or facing posteriorly (in the anatomical position) Pronation Supination
- 18. Eversion: Turning the foot so that the sole faces laterally Inversion: Turning the foot so that the sole faces medially Protraction: Moving a part forward Example: thrusting the chin forward Retraction: Moving a part backward Example: pulling the chin backward Elevation: Raising a part Example: shrugging the shoulders Depression: Lowering a part Example: drooping the shoulders
