Anterior root of spinal nerve

The formation of the spinal nerve from the dorsal and ventral roots
Latin	radix anterior nervi spinalis
Gray's	subject #208 916
MeSH	Ventral+Roots

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.
