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 muscles include the supraspinatus, the infraspinatus, the subscapularis and the teres minor, all of which are innervated by the subscapular and axillary nerves. The tendons of the rotator cuff combine to form one large band that is a 5 layer-structure.
