More Information about the Teres Minor Muscle

Derived from the Latin word 'teres' meaning rounded, the teres minor muscle is a narrow, elongated muscle and is one of the four muscles that make up the rotator cuff along with the supraspinatus, subscapularis and infraspinatus.  The teres minor muscle works closely with the infraspinatus.  The teres minor also plays a role as a protective reflex to enhance proprioception during functional movements.
