GENERAL HISTOLOGY

Detailed explanation-1: -Examples. Examples of this form of articulation are found in the hip, 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.

Detailed explanation-2: -The shoulder and wrist joint belong to the category of ball and socket joint. It 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.

Detailed explanation-3: -Hence, the shoulder joints and the hip joints have ball and socket type of joints, whereas the wrist joints are an example of hinge joints (maximum rotation of 180o, along with a single axis).
