Ventral root of spinal nerve - Wikipedia Ventral root of spinal nerve Ventral root of spinal nerve The formation of the spinal nerve from the dorsal and ventral roots Details Identifiers Latin radix anterior nervi spinalis MeSH D013126 TA A14. 2.00. 029 FMA 5979 Anatomical terminology ( edit on Wikidata ) In anatomy and neurology, the ventral root or anterior root is the efferent motor root of a spinal nerve. At its distal end, the ventral root joins with the dorsal root to form a mixed spinal nerve. Additional images Cervical vertebra Medulla spinalis A spinal nerve with its anterior and posterior.
