dorsal root of spinal nerve

Introduction

Pairs of spinal nerves form dorsal (sensory) & ventral (motor) roots.

Dorsal roots emerge from the dorsal horn of the spinal cord.

Dorsal roots have cell bodies in dorsal root ganglion.

The dorsal roots & ventral roots join in the intervertebral foramen.

Many rootlets may comprise the dorsal root of spinal nerves.

The rootlets coalesce to form the dorsal ramus of spinal nerve.
