The subscapular muscle (m. Subscapularis) is broad, thick, triangular in shape. It occupies almost the whole rib surface of the scapula. Has a fleshy origin on the surface of the subscapular fossa and lateral margin of the scapula. The flat tendon is attached to the small tubercle and crest of the small tubercle of the humerus. At the attachment site between the tendon and the capsule of the shoulder joint, there is a sucking bag of the subscapular muscle, which is usually communicated with the cavity of the shoulder joint.
The function of the subscapular muscle: turns the shoulder inwards (pronation), simultaneously leads the shoulder to the trunk.
Innervation of the subscapularis: subscapular nerve (CV-CVII).
Blood supply to the subscapular muscle: subscapular artery.
