Dorsal scapular nerve

Dorsal scapular nerve
Nerve: Dorsal scapular nerve
The right brachial plexus with its short branches, viewed from in front. (Dorsalis scapulae labeled at left, second from top.)
Latin nervus dorsalis scapulae
Gray's subject #210 932
Innervates rhomboid minor, rhomboid major, levator scapulae
From C5 of brachial plexus

The dorsal scapular nerve arises from the brachial plexus, usually from the plexus root (anterior/ventral ramus) of C5.

It provides motor innervation to the rhomboid muscles, which pull the scapula towards the spine and levator scapulae muscle, which elevates the scapula.
