Question

The cell bodies of autonomic postganglionic neurons are found in ANS ganglia. The cell bodies of another class of neuron are also found in ganglia (but not ANS ganglia). What are these other ganglia called? Determine the structural and functional classification of the neurons found in these other ganglia.
