Ganglionic cell bodies are located in which part of the nervous system?

• A. CNS
• B. PNS
• C. Brainstem
• D. Spinal cord

Answer: (B)

Ganglionic cell bodies are located outside the brain and spinal cord—in the peripheral nervous system. A ganglion is a cluster of neuron cell bodies that resides in the PNS, such as autonomic ganglia housing postganglionic neurons and dorsal root ganglia for sensory neurons. The central nervous system (brain and spinal cord, including the brainstem) contains cell bodies within nuclei and cortical areas, not in ganglia. Since ganglia are peripheral structures, the peripheral nervous system is the correct location.
