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 unipolar type, meaning they have only one projection. The dorsal root ganglia lie along the vertebral columna by the spine. The dorsal root ganglia develop in the embryo from neural crest cells.
