The '''suprascapular nerve''' arises from the trunk formed by the union of the fifth and sixth [[cervical nerves]]. It innervates the [[supraspinatus muscle]]s and [[infraspinatus muscle]]s.
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]].
