Detailed explanation-1: -Although teres major is not one of the four rotator cuff muscles, it is often used in musculotendinous transfer for rotator cuff deficits.

Detailed explanation-2: -Which muscle is not part of the rotator cuff? The teres major muscle is not part of the rotator cuff, although it is frequently confused with other muscles in the rotator cuff. The teres major performs similar functions to some of the rotator cuff muscles.

Detailed explanation-3: -The teres major is a thick muscle of the shoulder joint. It spans from the inferior aspect of the scapula to the proximal part of the humeral shaft. Unlike the teres minor, the teres major muscle does not attach to the capsule of the glenohumeral joint. Thus it is not regarded as part of the rotator cuff muscles.

Detailed explanation-4: -The teres minor is deep to the deltoid muscle. As a rotator cuff muscle, the teres minor stabilizes the ball-and-socket glenohumeral joint by helping hold the humeral head (ball) into the shallow glenoid cavity of the scapula (socket). The teres minor also laterally or externally rotates the arm at the shoulder joint.

Detailed explanation-5: -Subscapularis. Infraspinatus. Teres minor. Supraspinatus.
