Anatomy-Skeletal System Types of Joints and Joints Structures

Anatomy-Skeletal System Introduction n What medical term is used to describe where two bones

Anatomy-Skeletal System Introduction n What medical term is used to describe where two bones join together? n What types of joints do you know about?

Anatomy-Skeletal System Terminology Ligament n Connect bone to bone n Fibrous connective tissue n

Anatomy-Skeletal System Terminology Ligament n Connect bone to bone n Fibrous connective tissue n Range of Motion (ROM) n Measurable degrees of anatomical movement at a particular joint n

Anatomy-Skeletal System Objectives n Students will be able to: n Define terms that are

Anatomy-Skeletal System Objectives n Students will be able to: n Define terms that are used to describe the types of joints. n Define the types of joints. n Identify the bony anatomy of the joints. n Give examples for each type of joint. n Identify movements that occur at specific joints.

Anatomy-Skeletal System Types of Joints n Immovable Joints n Where bone come in close

Anatomy-Skeletal System Types of Joints n Immovable Joints n Where bone come in close contact with each other n No active movement n Cranial joints

Anatomy-Skeletal System Types of Joints n Slightly Movable Joints n Allows limited movement n

Anatomy-Skeletal System Types of Joints n Slightly Movable Joints n Allows limited movement n Vertebral column n Except C 1 &C 2

Anatomy-Skeletal System Types of Joints Freely Movable Joints n Synovial Joints n Most joints

Anatomy-Skeletal System Types of Joints Freely Movable Joints n Synovial Joints n Most joints n Bones covered with hyaline cartilage n Surrounded by synovial capsule n

Anatomy-Skeletal System Types of Joints Synovial Capsule n Joint Capsule n Surrounds joint n

Anatomy-Skeletal System Types of Joints Synovial Capsule n Joint Capsule n Surrounds joint n Outer layer of ligament n Inner layer secretes synovial fluid n Joint lubricant n

Anatomy-Skeletal System Joint Structure- Ball & Socket n n n The ball shaped surface

Anatomy-Skeletal System Joint Structure- Ball & Socket n n n The ball shaped surface of one bone fits into the cup shaped socket of another bone ROM occurs in all directions n Flexion-Extension. Abduction-Adduction -Rotation. Circumduction Shoulder & Hip

Anatomy-Skeletal System Joint Structure- Hinge n n n Convex surface of one bone fits

Anatomy-Skeletal System Joint Structure- Hinge n n n Convex surface of one bone fits into the concave depression of another bone ROM occurs in one plane n Flexion-Extension Elbow, Knee & Interphalangeal Joints

Anatomy-Skeletal System Joint Structure- Pivot n n n Cylindrical or rounded surface of one

Anatomy-Skeletal System Joint Structure- Pivot n n n Cylindrical or rounded surface of one bone fits into the ring of another bone or ligament ROM occurs in rotation only Radioulnar & Atlas/Axis

Anatomy-Skeletal System Joint Structure- Gliding n n n Articular surfaces are flat or nearly

Anatomy-Skeletal System Joint Structure- Gliding n n n Articular surfaces are flat or nearly flat ROM occurs as gliding (sliding) or twisting Carpals & Tarsals

Anatomy-Skeletal System n Articular surfaces are Joint Structure. Saddle n n both concave and

Anatomy-Skeletal System n Articular surfaces are Joint Structure. Saddle n n both concave and convex ROM occurs as Flexion. Extension-Adduction. Abduction. Circumduction n No rotation 1 st Carpometacarpal Joint (CM) n Trapezium & 1 st Metacarpal

Anatomy-Skeletal System Joint Structure- Ellipsoid/Condyloid n n n Oval shaped condyloid surface of one

Anatomy-Skeletal System Joint Structure- Ellipsoid/Condyloid n n n Oval shaped condyloid surface of one bone fits into the ellipsoidal depression (ellipse) of another bone ROM occurs as Flexion. Extension-Adduction. Abduction-Circumduction n No rotation Metacarpophalangeal Joints Metatarsophalangeal Joints n MP Joints
