swelling of cell bodies within a nerve is called
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.
