dorsal scapular nerve
anatomy
Quick Summary
The dorsal scapular nerve is a nerve that supplies the rhomboid muscles and the levator scapulae muscle. It originates from the brachial plexus, specifically from the C5 spinal nerve root. This nerve is part of the peripheral nervous system, which relays sensory and motor impulses between the central nervous system and the rest of the body. The brachial plexus itself is a network of nerves formed by the C5-T1 spinal nerve roots, providing innervation to the shoulder and upper extremity.1
