The teres major muscle is a muscle of the upper limb and one of six scapulohumeral muscles. It is a thick but somewhat flattened muscle, innervated by the lower subscapular nerve (c5,c6).

Origin and insertion

It arises from the oval area on the dorsal surface of the inferior angle of the scapula, and from the fibrous septa interposed between this muscle and the rotator cuff lateral rotator pair of the teres minor and infraspinatus.

The fibers of teres major insert into the medial lip of the intertubercular sulcus of the humerus.

Relations

The tendon, at its insertion, lies behind that of the latissimus dorsi, from which it is separated by a bursa, the two tendons being, however, united along their lower borders for a short distance.

Together with teres minor muscle, teres major muscle forms the axillary space, through which several important arteries and veins pass. Teres major is not part of the rotator cuff of the shoulder, but it does combine with the deltoideus to make the six scapulohumeral muscles.

The teres major muscle is innervated by the lower subscapular nerve of the brachial plexus.

Action

The teres major is a medial rotator and adductor of the humerus and assists the latissimus dorsi in drawing the previously raised humerus downward and backward (extension, but not hyper extension). It also helps stabilize the humeral head in the glenoid cavity.
