A Cadaveric Investigation of the Dorsal Scapular Nerve

Figure 2

(a) An anterolateral view of the right neck region of a 90-year-old female cadaver in the supine position. The DSN branches from C4 and pierces the middle scalene muscle. (b) In the prone position, the DSN travels posteroinferiorly after piercing the middle scalene muscle to supply the levator scapulae, rhomboid minor, and rhomboid major muscles. The rhomboid muscles are reflected laterally from their origin to show the route of the DSN.
