The subscapularis is a large triangular shoulder muscle that lies on the front surface of the scapula. It originates in the concave area called the subscapular fossa and converges at its lower end into a tendon which inserts in the lesser tuberosity of the humerus. The subscapularis is innervated by the upper and lower subscapular nerves which branch from the fifth and sixth cervical nerves. It is supplied by branches of the subscapular artery. This muscle rotates the head of the humerus when the arms are raised to prevent displacement. It is also used to move the arms forward and down. Research Subscapularis
