Dorsal scapular nerve originates from which spinal level?

Explanation:
The dorsal scapular nerve mainly comes from the C5 ventral ramus of the brachial plexus. It travels to innervate the rhomboid major, rhomboid minor, and often levator scapulae, which ties its origin to the C5 level. Some texts note a small contribution from C4, but C5 is the standard and most consistently cited origin. That’s why the best answer is C5.
