Ball and socket joint

allows rotational movement but prevents transtional movement to the member attached to it

A ball and socket joint (enarthrosis, spheroidal joint) is a joint in which the ball-shaped surface of a bone fits into the cup-like indentation of another bone. This type of joint allows the bone to move in a 360° angle—with more freedom than other joints.[1]
