Preferred Label : dorsal root ganglion;
Uberon definition : Sensory ganglia located on the dorsal spinal roots within the vertebral column. The
spinal ganglion cells are pseudounipolar. The single primary branch bifurcates sending
a peripheral process to carry sensory information from the periphery and a central
branch which relays that information to the spinal cord or brain. (MSH) * ganglion
found on the posterior root of each spinal nerve, composed of the unipolar nerve cell
bodies of the sensory neurons of the nerve. (CSP);
Uberon synonym : spinal ganglion part of peripheral nervous system; spinal ganglion; ganglion spinalis; ganglion of dorsal root;
Uberon related term : dorsal root ganglia; DRG; ganglion spinale; posterior root ganglion;
Uberon Development note : The sensory ganglia of spinal nerves arise only from the neural crest, whereas many
sensory ganglia of the 'dorsal' cranial nerves arise from epibranchial placodes as
well as the neural crest[DOI:10.1093/icb/icn065];
Uberon Homology note : From comparative analyses of craniate brains, a morphotype of the brain in the earliest
craniate stock can be constructed. In marked contrast to cephalochordates, the ancestral
craniate morphotype had a plethora of unique features, which included a telencephalon
with pallial and subpallial parts, paired olfactory bulbs with substantial projections
to most or all of the telencephalic pallium, paired lateral eyes and ears, a lateral
line system for both electroreception and mechanoreception, spinal cord dorsal root
ganglia, and an autonomic nervous system.[well established][VHOG];
