Teres major muscle

Last revised by Dr Bahman Rasuli on 27 Mar 2021

Teres major muscle is one of the seven scapulohumeral muscles that act around the glenohumeral joint to facilitate shoulder movement.

Summary

Gross anatomy

The muscle originates from the dorsal surface of the inferior angle of the scapula and inserts on the medial lip of the intertubercular groove of the humerus. It is related to the latissimus dorsi muscle which wraps around the lower border of teres major. The tendon of the teres major lies posterior to the tendon of the latissimus dorsi and there is a bursa between them.
