In anatomy and neurology the dorsal root (or posterior root) is the afferentsensory root of a spinal nerve. At the distal end of the dorsal root is the dorsal root ganglion which contains the cell bodies of the nerve fibres contained in the root. If the dorsal root of a spinal nerve were severed it would lead to numbness in certain areas of the body.The lateral division of the dorsal root contains lightly myelinated and unmyelinated fibres of small diameter.
