Which of the following is not part of the rotator cuff?
Select Your Answer:
The rotator cuff is the group of muscles and their tendons that act to stabilize the shoulder. Muscles composing the rotator cuff include supraspinatus, infraspinatus, teres minor, and subscapularis.
The subscapularis is a flat muscle originating from the lower scapula and inserting on the lesser tubercle behind the insertion of latissimus dorsii. It primarily assists in medial rotation and adduction of the humerus.
Teres minor is a part of the rotator muscles and assists in lateral rotation.
Along with the teres minor, it forms the axillary space through which the axillary nerve, posterior humeral circumflex vessels, and scapular circumflex vessels pass.
