normal shoulderThe shoulder is made up of three bones: the upper arm bone (humerus), the shoulder-blade (scapula), and the collarbone (clavicle). Surrounded with tendons and muscles, the shoulder  provides a great range

The shoulder bones are connected across two joints: the ACJ (collar-bone to shoulder-blade) and the GHJ (arm bone to shoulder-blade).

The arm is kept in the socket by the rotator cuff tendons and several ligaments. The rotator cuff tendons also help raising and turning the arm in space. Tendons do so without too much friction by virtue of a lubricating sac called the bursa that lies between the tendon and the bone. There is one between the rotator cuff and the  top part of the shoulder-blade (acromion).  There is another one between the shoulder-blade muscles and the back side of your chest.

Any of the structures mentioned above can be a source of pain or malfunction when diseased or injured.
