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 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.
