In anatomy and neurology, the dorsal root ganglion (or spinal ganglion) is a nodule on a dorsal root that contains cell bodies of neurons in afferent spinal nerves.
All of the axons in the dorsal root convey somatosensory information, bringing sensory information into the brain and spinal cord. These neurons are of the pseudo-unipolar type, meaning they have two axons, one that conveys sensory information from the body to the soma of the neuron and one from the soma to the junction in the dorsal horn of the spinal cord.
The dorsal root ganglia lie along the vertebral columna by the spine.
[edit] Origin
The dorsal root ganglia develop in the embryo from neural crest cells.
