Rotator_cuffWhat is the Rotator Cuff?

Four muscles that originate on the shoulder blade (scapula) all essentially converge into a common tendon to attach at the front, top and back of the head of the humerus (the bone of the upper arm). Collectively, they constitute the rotator cuff. You may recall that tendons connect muscle to bone. Those of the rotator cuff are no different.

The muscles that contribute to this tendon are responsible for different actions.
