JOINT Classifications

6 types of synovial jts • synarthrodial: immovable fibrous joints (i. e. , suture of skull) • amphiarthroidial: cartilaginous jts; slightly moveable (i. e. , symphesis) • diarthrodial: synovial jts; freely moveable • -gliding (plane): flat surfaces, i. e. , vertebrae • -hinge: angular motion, i. e. , elbow. • -condylar or ellipsoidal: head shaped bone that fits into a concave surface that allows for motion, i. e. , wrist. • -saddle: one bone end that is convex, which fits into a concave bone end; allows all motion as in condylar ft; i. e. , thumb. • -pivot: head of bone surround by ring of cartilage or bone to allow rotation, i. e. , C 1/C 2 jt. • ball and socket: head shaped bone end that fits into a cup-shaped socket, i. e. , hip.
