Dorsal root ganglia are part of which nervous system?

Dorsal root ganglia are part of which nervous system?

• A. Peripheral nervous system
• B. Central nervous system
• C. Autonomic nervous system
• D. Enteric nervous system

Answer: (A)

Dorsal root ganglia are clusters of sensory neuron cell bodies located outside the brain and spinal cord, along the dorsal roots of spinal nerves. This places them in the peripheral nervous system. The neurons have a peripheral process that picks up sensory information from the body and a central process that enters the spinal cord to relay that information. They’re not part of the CNS, and they’re not autonomic or enteric ganglia, which are separate components of other divisions.
