supraspinatous fossa
The supraspinatous fossa (supraspinatus fossa, supraspinous fossa) of the posterior aspect of the scapula is smaller than the infraspinatous fossa, concave, smooth, and broader at its vertebral than at its humeral end. Its medial two-thirds give origin to the Supraspinatus.
== Structure ==
The fossa can be exposed by the removal of skin and the superficial fascia of the back and the trapezius muscle.
The supraspinatous fossa is bounded by the spine of scapula on the inferior side, acromion process on the lateral side and the superior angle of scapula on the superior side.
Supraspinatus muscle originates from the supraspinatous fossa. Distal attachment of the levator scapulae muscle is also on the medial aspect of the fossa.
