The Suprascapular arises from the trunk formed by the union of the fifth and sixth cervical nerves .
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 .
