and tendons which have the fundamental task of stabilizing the glenohumeral joint of the shoulder.
The rotator cuff is made up of the supraspinatus, infraspinatus, teres minor and subscapularis muscles, and their respective tendons.
Located deep in major sub-muscles (eg trapezius), the rotator cuff muscles all originate at the scapula level (the precise origin varies from muscle to muscle) and end their course on the proximal portion of the humerus.
In addition to having a stabilizing function towards the glenohumeral joint, the rotator cuff also intervenes in the abduction, external and internal rotation movements of the shoulder.
