Detailed explanation-1: -The supraspinatus muscle, the most superiorly located of the rotator cuff muscles, resides in the supraspinous fossa of the scapula, superior to the scapular spine.

Detailed explanation-2: -Supraspinatus lies deep to the trapezius muscle and superior to the spine of the scapula and infraspinatus muscle.

Detailed explanation-3: -Supraspinatus: This muscle stretches from the top of the scapula to the top of the humerus, at the ball of your shoulder joint.

Detailed explanation-4: -361 The supraspinatus muscle arises from the fossa that lies superior to the scapular spine on the posterior portion of the scapula, passes beneath the acromion and the acromioclavicular joint, and attaches to the superior aspect of the greater tuberosity.

Detailed explanation-5: -The scapula forms the posterior of the shoulder girdle. It is a sturdy, flat, triangular bone. The scapula provides attachment to several groups of muscles. The intrinsic muscles of the scapula include the rotator cuff muscles, teres major, subscapularis, teres minor, and infraspinatus.
