Detailed explanation-1: -The superior glenohumeral ligament extends from the supraglenoid tubercle of scapula to the proximal aspect of the lesser tubercle of humerus. Along with the coracohumeral ligament, it supports the rotator interval and prevents inferior translation of the humeral head, particularly during shoulder adduction.

Detailed explanation-2: -[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. [2] The latter also includes minor articulations of the sternoclavicular (SC), acromioclavicular (AC), and scapulothoracic joints.

Detailed explanation-3: -The shoulder is structurally and functionally complex as it is one of the most freely moveable areas in the human body due to the articulation at the glenohumeral joint. It contains the shoulder girdle, which connects the upper limb to the axial skeleton via the sternoclavicular joint.

Detailed explanation-4: -The glenohumeral joint, also known as the shoulder joint, is a ball and socket type of synovial joint: the ball being the head of the humerus, and the socket being the glenoid cavity of the scapula.
