Document Summary

Structure what holds the joint together. Synovial held by ligament/fluid not as tightly associated ~> typically synovial. Amphiarthroses small movement (ex. radius over ulna) Joined via fibrous ct no cavity little movement. Sutures (synostose = no movement: short ct fiber seams. Syndesmoses: ligament/interosseous membrane limited movement. Gomphoses: peg in socket (ex. tooth in bony socket) (cid:1) Synchondroses: growth areas (ex. epiphyseal plates) 2 bony areas together, ex. Symphysis: articular surfaces covered with hyaline cartilage, fibrocartilage in between as linking plate, ex. Bursa = sac of synovial fluid where things rub against bone physical wear/tear. Tendon sheath = elongated bursa wrapping around a tendon. 1) articular surfaces deep ball/socket = good stability. 2) ligaments more = more strength: can improve ~6% stretching. 3) muscle tone tendons of muscles crossing joints. Injuries-sprains: partially torn ligaments will slowly replace themselves (poor vascularization, cartilage injuries.
