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.
These tendons are called the subscapularis tendon, the supraspinatus tendon, the infraspinatus tendon, and the teres minor tendon. These tendons come together to surround the front, back, and the top of the shoulder socket acting as a 'cuff' to connect your humerus to the rotator cuff muscles.
