Musculus teres major

The video tutorial discusses the teres major muscle, its origin, anatomical connections, and functions. It explains how the teres major is part of the dorsal shoulder muscles but not the rotator cuff. The muscle originates from the back of the shoulder blade and is closely linked to the latissimus dorsi, forming the posterior armpit fold. The teres major is innervated by nerves from the brachial plexus and is responsible for internal rotation, adduction, and retroversion of the arm.
