Infraspinous fossa

The infraspinous fossa is a concave depression located on the posterior surface of the scapula, below the spine of the scapula. It serves as the origin site for the infraspinatus muscle, which is one of the rotator cuff muscles. This muscle plays a key role in external rotation of the shoulder joint and stabilization of the humeral head within the glenoid cavity.
