Histology of the Dorsal Root Ganglion. Many of the cell bodies of the sensory and motor neurons of the peripheral neves are grouped into nodules or swellings called ganglia. There are two major types of ganglia in the peripheral nervous system: the craniospinal ganglia contain the cell bodies of sensory neurons of cranial and spinal nerves. The autnomic ganglia of the autonomic nervous system contain the cell bodies of the motor neurons of autonomic nerves.
The Ganglia of the Spinal Nerves-The Dorsal Root Ganglia. Each of the spinal nerves is equipped with a spinal ganglion, commonly called a dorsal root ganglion. The dorsal root ganglion is a swelling found along the dorsal root of the nerve.The dorsal root is one of two nerve roots associated with each spinal nerve.hrough the dorsal root, pseudounipolar sensory axons continue, exclusively, from the nerve, to the spinal cord, entering the spinal cord along the cord's dorsolateral surface. The dorsal root ganglion contains the cell bodies of these pseudounipolar sensory neurons.
