September 23rd, 2010 Human Anatomy – Rotator Cuff
A rotator cuff is a set of muscles and tendons in the shoulder that connects the humerus (upper arm bone) with the scapula (shoulder blade). It allows the shoulder to rotate by securely holding the ball of the humerus in its socket. In fact, the rotator cuff allows this ball and socket to have the widest variety of motion among all the joints in the body.
