Some fibers arise from tendinous laminæ which intersect the muscle and are attached to ridges on the bone; others from an aponeurosis, which separates the muscle from the Teres major and the long head of the Triceps brachii.

Teres major is a muscle of the upper limb and one of six scapulohumeral muscles. ... Triceps brachii The triceps brachii muscle is a large three-headed skeletal muscle found in humans. ...


The fibers pass lateralward, and, gradually converging, end in a tendon which is inserted into the lesser tubercle of the humerus and the front of the capsule of the shoulder-joint. The lesser tubercle, although smaller, is more prominent than the greater tubercle: it is situated in front, and is directed medialward and forward. ... The humerus is a long bone in the arm or fore-legs (animals) that runs from the shoulder to the elbow. ... This article does not cite its references or sources. ...


The tendon of the muscle is separated from the neck of the scapula by a large bursa, which communicates with the cavity of the shoulder-joint through an aperture in the capsule. A bursa is also a fluid filled sac located between a bone and tendon which normally serves to reduce friction between the two moving surfaces. ...


Nerves

The Subscapularis is supplied by the fifth and sixth cervical nerves through the upper and lower subscapular nerves. The Subscapularis muscle is a muscle of the human body. ...


Actions

The Subscapularis rotates the head of the humerus medially; when the arm is raised, it draws the humerus forward and downward. It is a powerful defence to the front of the shoulder-joint, preventing displacement of the head of the humerus. The humerus is a long bone in the arm or fore-legs (animals) that runs from the shoulder to the elbow. ... This article does not cite its references or sources. ...
