Detailed explanation-1: -Anatomically, a dorsal root ganglion (DRG) emerges from the dorsal root of the spinal nerves. They carry sensory messages from various receptors (i.e., pain and temperature) at the periphery towards the central nervous system for a response. The role of DRG in chronic pain has been well established.

Detailed explanation-2: -The dorsal root is sensory and the ventral root motor; the first cervical nerve may lack the dorsal root. Oval swellings, the spinal ganglia, characterize the dorsal roots. They are formed of nerve cells that give rise to the sensory nerve fibres.
