Cluster of neurons in a dorsal root of a spinal nerve
Dorsal root ganglion
A dorsal root ganglion (DRG) from a chicken embryo (around stage of day 7) after incubation overnight in NGF growth medium stained with anti-neurofilament antibody. Neurites growing out of the ganglion are visible.
A spinal nerve with its ventral and dorsal roots. The dorsal root ganglion is the "spinal ganglion", following the dorsal root.

Anatomical terminology

A dorsal root ganglion (or spinal ganglion; also known as a posterior root ganglion[1]) is a cluster of neurons (a ganglion) in a dorsal root of a spinal nerve. The cell bodies of sensory neurons known as first-order neurons are located in the dorsal root ganglia.[2]
The axons of dorsal root ganglion neurons are known as afferents. In the peripheral nervous system, afferents refer to the axons that relay sensory information into the central nervous system (i.e. the brain and the spinal cord).
