Hi Nick,

This may be basic...but going off Dr. Zagon's notes on the ANS...
Nerves in the ANS are always a two-neuron system (one preganglionic and one post ganglionic). So, I think the question should read "The vagus nerve contains postganglionic parasympathetic NEURONS (not nerves)". Which, I think, should be true. Regardless of where the synapse occurs (within the organ or collaterally), the postganglionic neuron is still part of the nerve.

Does anyone else agree with this?
