Detailed explanation-1: -In ball and socket joint globe like head of one bone fits into cup like concavity of another bone. The types of movements possible are flexion, extension, internal rotation, lateral rotation, abduction, adduction and circumduction . Examples of ball and socket joint are shoulder joint and hip joint.

Detailed explanation-2: -The hip and the shoulder are both ball and socket joints that have cartilage, ligaments, labrum, and a surrounding capsule. There are some differences between these joints that influence the treatment for injuries and painful conditions. The hip is much more constrained or inherently stable than the shoulder.

Detailed explanation-3: -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-4: -The shoulder is a ball and socket joint made up of three bones, namely the humerus, scapula, and clavicle. The end of the humerus or upper arm bone forms the ball of the shoulder joint. An irregular shallow cavity in the scapula called the glenoid cavity forms the socket for the head of the humerus to fit in.

Detailed explanation-5: -The glenohumeral joint is structurally a ball-and-socket joint and functionally is considered a diarthrodial, multiaxial, joint. [1] The glenohumeral articulation involves the humeral head with the glenoid cavity of the scapula, and it represents the major articulation of the shoulder girdle.
