Supraspinous fossa

Other Terms: Supraspinous fossa of scapula, Fossa supraspinata, Fosse supraépineuse

Description

This fossa is the ditch-like concavity above the spine of the scapula. This comprises approximately the upper third of the dorsal surface of the scapula. Filling its concave surface is the supraspinatus muscle. This surface communicates with the infraspinous fossa through the spinoglenoid notch.

Etymology

The term supraspinous comes from the Latin supra meaning above and spine, referring to the boney support ridge on the posterior surface of the scapula. Fossa derives from the Latin verb fodere meaning to dig. From this, fossa came to mean a trench, ditch, or hole.
