dorsal root ganglia

dorsal root ganglia

Collections of the bodies of sensory spinal nerve cells lying outside but alongside the spinal cord, one for each spinal segment. The sensory spinal nerves contain the long dendrites of these cells; the axons pass into rear part of the spinal cord. Also known as posterior root ganglia.
