The infraspinatus is a thick triangular muscle that occupies much of the infraspinous fossa of the scapula.

The following are muscles of arm rotation and adduction. For each, give its origin (s) and insertion (s) and whether or not it is part of the rotator cuff. The supraspinatus is a relatively small muscle which is located in the upper shoulder region. The supraspinatus muscle is one of the four rotator cuff muscles, which also include: the infraspinatus, teres minor, and subscapularis muscles.
