What is a Belly Press Test For Shoulder?
The subscapularis is a large triangular muscle on the shoulder joint's anterior side. It originates from the subscapular fossa, which is part of the scapula (shoulder blade) and attaches to the lesser tubercle of the humerus. The subscapularis is essential in internally rotating and adducting the arm and stabilizing the shoulder joint. It is one of four muscles that comprise the rotator cuff and is vital in maintaining shoulder joint integrity.
