Shoulder
Dorsal scapular nerve
The rhomboid muscles have been cut away. The scapula hs been retracted laterally from the thorax so that the deep surfaces of the levator scapulae(2) and serratus anterior (4,11) muscles are exposed. The dorsal scapular nerve (3) can be traced through the levator scapular muscle toward its termination in the rhomboid muscles (see previous view).
