Dr. Ebraheim's animated educational video describing muscles of the rotator cuff. The rotator cuff is a group of four muscle; the supraspinatus, infraspinatus, teres minor, and the subscapularis . These four rotator cuff muscles all originate from the scapula and insert into the proximal humerus . Supraspinatus The supraspinatus muscle arises from the supraspinous fossa and is inserted into the superior facet of the greater tubercle of the humerus . The supraspinatus abducts the arm and stabilizes the humerus. A tear in the supraspinatus muscle will result in the inability to abduct the shoulder.
