The ball and socket joint is a type of synovial joint in which the ball-shaped surface of one rounded bone fits into the cup-like depression of another bone.Ball and Socket hoint is present where the round head of the femur (ball) rests in the cup-like acetabulum (socket) of the pelvis and in the shoulder joint, where the rounded upper extremity of the humerus (ball) rests in the cup-like glenoid fossa (socket) of the shoulder blade.
