Teres Minor Muscle

Saturday, October 15, 2011

The teres minor is the smaller of two muscles in the shoulder region which adducts the arm and rotates it laterally. Narrow and elongated, the teres minor originates from the dorsal surface of the axillary border of the scapula, inserting into the lowest of the three impressions on the greater tubercle of the humerus. It is innervated by the axilliary nerve and supplied by the posterior circumflex humeral artery.
