immovable joints
amphiarthrosis
slightly movable joints
diarthrosis
freely movable joints
movement of synovial joints are determined by…
form/type of the motion,
direction of the motion,
relationship of the body parts involved
synovial joint movements grouped into four categories…
gliding, angular movements, rotation, and special movements
gliding:
