|This is 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. Axons growing out of the ganglion are visible.|
|Latin||g. sensorium nervi spinalis|
|Gray's||subject #185 750|
|A spinal nerve with its anterior and posterior roots.|
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.
The dorsal root ganglia develops in the embryo from neural crest cells.
