Dorsal scapular nerve

Last revised by Craig Hacking on 27 Jul 2022

The dorsal scapular nerve is a branch from the C5 root of the brachial plexus and supplies the rhomboid muscles.

Gross anatomy


Posterior aspect of the C5 root of the brachial plexus.


It courses through scalenus medius then accompanies the dorsal scapular vessels inferiorly, deep to levator scapulae where it lies on serratus posterior superior


It supplies both rhomboids on their deep surfaces and may also supply levator scapulae via a separate branch.
