The supraspinatus muscle is one of the musculotendinous support structures called the rotator cuff that surround and enclose the shoulder. It helps to resist the inferior gravitational forces placed across the shoulder joint due to the downward pull from the weight of the upper limb.
The four muscles that form the rotator cuff are the supraspinatus, infraspinatus, teres minor, and subscapularis. Often the mnemonic S.I.T.S is used to help remember the muscles that make up the rotator cuff. Supraspinatus: The supraspinatus muscle originates above the spine of the scapula and inserts on the greater tuberosity of the humerus.
