Lecture Objectives 10 1. Describe the anatomy different kinds of joints and the type of movement allowed Functional categories Synarthroses - immovable Amphiarthroses - slightly moveable Diarthroses - freely movable Structural Categories Fibrous - bones linked by collagen fiber of connective tissue - little to no movement - Synarthroses and Amphiarthroses Cartilaginous - bones linked by cartilage connective tissue - little to no movement - S ynarthroses and Amphiarthroses Synchondroses - bones united with hyaline cartilage Symphyses - bones united by fibrocartilage Synovial - ends of bones not connected by connective tissue; separated by fluid filled joint cavity - movement iarthroses 2. Describe the synovial joint anatomy in detail Articular cartilage - hyaline cartilage at ends of bone Joint cavity - potential space containing synovial fluid Articular capsule - two layers - fibrous layer (outside) synovial membrane (inside) - lines the capsule Reinforcing ligaments - connective tissue from bone to bone - provides support Nerve and blood vessels - proprioception which is knowing where you are in space Bursa & Tendon Sheaths - closed sac ment to reduce friction Tendons - connective tissue that connect muscle to bone Articular disc (meniscus) - fibrocartilage disc to absorb joint shock or help joint fit Labrum - fibrocartilage ring that deepens synovial joint 3. Describe the movements allowed by synovial joints - motion terms Gliding - one flat bone glides/slips over another without angulation or rotation Flexion - decreasing the angle between two bones - sagittal plane Extension - increasing the angle between two bone - sagittal plane Hyperextension - further increase the angle between two bone - sagittal plane Abduction - away from the body in the lateral plane - frontal/coronal plane Adduction - toward the body in the lateral plane - frontal/coronal plane Circumduction - combo of a lot of movements - frontal/coronal plane Rotation - increasing or decreasing the angle between two bones - transverse plane lateral - away from the midline Medial - toward the midline Special Movements Protonation - radius rotates over ulan Supination - radius and ulna are parallel Dorsiflexion - toes toward the superior part of the body ( toes up) Plantar flexion - toes away from the superior part of the body ( toes down) - Plant feet into the GROUND - toes point down Invention - toward midline Eversion - away from midline Retraction - movement of a body part in the anterior direction, i.e. being drawn forwards Protraction - the opposite of the movement of retraction Elevation - movement to a more superior position Depression - movement to a more interior position Opposition and reposition - thumbs 4. Describe the 6 types of synovial joints and what kinds of movement each type allows Plane joint - flat articular surfaces - none axial movement - gliding Hinge joint - uniaxial movement medial/lateral axis - flexion and extension Pivot joint - uniaxial movement Vertical axis - rotation Condarler joint - biaxial movement - movement over two planes Flexion and extension, and adduction and adduction Saddle joint - biaxial movement - movement over two planes Flexion and extension, and adduction and adduction - T humb Ball-and-socket joint - Multiaxial movement Flexion and extension, and adduction and adduction, and rotation 5. Identify the components of the knee and shoulder joint Knee Shoulder *images copied from doctor flynn's lecture slides* 6. Describe the relationship between stability and flexibility As stability increase, flexibility decreases, vice a versa
