|Nerve: Suprascapular nerve|
|The suprascapular, axillary, and radial nerves. (Suprascapular labeled at upper left.)|
|The right brachial plexus with its short branches, viewed from in front. (Suprascapular labeled at upper left.)|
|Gray's||subject #210 932|
|From||C5–C6 of brachial plexus|
The suprascapular nerve arises from the trunk formed by the union of the fifth and sixth cervical nerves. It innervates the supraspinatus muscles and infraspinatus muscles.
It runs lateralward beneath the Trapezius and the Omohyoideus, and enters the supraspinatous fossa through the suprascapular notch, below, the superior transverse scapular ligament; it then passes beneath the Supraspinatus, and curves around the lateral border of the spine of the scapula to the infraspinatous fossa.
In the supraspinatous fossa it gives off two branches to the Supraspinatus muscle, and an articular filament to the shoulder-joint; and in the infraspinatous fossa it gives off two branches to the Infraspinatous muscle, besides some filaments to the shoulder-joint and scapula.
