Teres minor muscle (Musculus teres minor)

Teres minor is a posterior muscle of the shoulder that extends between the scapula and the head of humerus. It is one of the four muscles of the rotator cuff, along with the supraspinatus, infraspinatus and subscapularis. 

Rotator cuff muscles act together to control the movements of the humeral head and stabilize it within the glenoid cavity of the shoulder joint, as the arm moves in various directions. Every muscle within the group also has its own specific role, and that of teres minor is to externally rotate and adduct the arm.

This article will discuss the anatomy and function of teres minor muscle.
