Quizplus · Accepted Answer

The structure labeled 3 in the diagram is a parasympathetic postganglionic neuron. This is because it is located after the ganglion (structure labeled 2), indicating that it is a postganglionic neuron, and it is part of the parasympathetic nervous system (as opposed to the sympathetic nervous system, which would have a sympathetic postganglionic neuron at this location).
