This figure shows the anatomy of the capsule and the rotator cuff.
The rotator cuff is made up of tendons and the capsule is made up
of ligaments (gristle). They work together to help hold the
ball (humeral head) into the socket (glenold).
This is the front view of the shoulder. The ball and socket can be
seen inside the rotator cuff muscles. The bony process in front of
the cuff is the coracoid. The bony structures on top of the
shoulder are called the acromion and the clavicle. The biceps
tendon is running on the outside of the shaft.
These are the four muscles of the rotator cuff. They are used to
move the ball (humeral head) within the socket (glenold). The ball
(humeral head) is superimposed over the socket (glenold).
This is the bony anatomy of the anterior part of the shoulder.
The rotator cuff muscles pull on the ball (humeral head) to get it to
move.
