Question

Where does the motor neurons of the autonomic nervous system exist?

• A. Posterior vagal trunks
• B. Autonomic ganglia
• C. Vagus nerves
• D. Thoracic nerves

Answer 1

Answer: (B)

Autonomic ganglia

• Autonomic ganglia are clusters of neuronal cell bodies and their dendrites.
• They are essentially a junction between autonomic nerves originating from the central nervous system and autonomic nerves(motor and sensory nerves) innervating their target organs in the periphery. Hence, the motor neurons of the autonomic nervous system exist at Autonomic ganglia.
So, the correct answer is 'Autonomic ganglia'.
