external definition
  • In anatomy and neurology, the dorsal root (or posterior root) is the afferent sensory root of a spinal nerve. At the distal end of the dorsal root is the dorsal root ganglion, which contains the neuron cell bodies of the nerve fibres conveyed by 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 axons of small diameter. These transmit pain and temperature sensation from the body. These fibers cross through the anterior white commissure to form the Anterior lateral system in the lateral funiculus. The medial division of the dorsal root contains myelinated axons of larger diameter. These transmit information of discriminative touch, pressure, vibration, and conscious proprioception originating from spinal levels C2 through S5. These fibers are pushed in towards the posterior medial sulcus to form the fasciculus gracilis and the fasciculus cuneatus. [WP,unvetted][Wikipedia:Posterior_root_of_spinal_nerve].
