Detailed explanation-2: -The term “subscapularis” means under (sub) the scapula (wingbone). It is part of the four rotator cuff muscles, the other three are the supraspinatus, infraspinatus and teres minor muscles. The subscapularis is the largest and strongest muscle of the rotator cuff.

Detailed explanation-3: -The rotator cuff consists of four muscles. These are the subscapularis, the supraspinatus, the infraspinatus and the teres minor muscles. These muscles end in short, flat, broad tendons which fuse intimately with the fibrous capsule to form the musculotendinous cuff.

Detailed explanation-4: -The subscapularis muscle’s primary function is internal rotation but can also aid in adducting the humerus. The subscapularis nerve innervates the muscle. The subscapular artery provides blood supply, and lymph drainage flows into the axillary nodes.
