Summary
The dorsal/posterior nerve root is an afferent nerve that brings in sensory information from the periphery to the spinal cord. The dorsal root ganglion, containing the cell bodies of the sensory afferent fibers, is located outside the spinal canal. These fibers then travel in the posterior root and enter the spinal cord via the dorsal horn, where they synapse with neurons in various laminae (substantia gelatinosa) before ascending either in the dorsal columns ipsilaterally (touch, vibration, and proprioception) or in the spinothalamic tract contralaterally (pain and temperature).
