The supraspinatus (plural supraspinati, from Latin supraspinatus) is a relatively small muscle of the upper back that runs from the supraspinatous fossa superior of the scapula (shoulder blade) to the greater tubercle of the humerus. It is one of the four rotator cuff muscles and also abducts the arm at the shoulder.
The rotator cuff is a group of four muscles that come together as tendons to form a cuff over the head of the humerus (upper arm bone). The four musclesâsupraspinatus, infraspinatus, subscapularis and teres minorâoriginate from the scapula (shoulder blade). The rotator cuff tendons attach to the head of the humerus in special spots referred to as the greater and lesser tuberosities.
