Question

Two-neuron system: Parasympathetic NS

Accepted Answer

1. Pre-ganglionic cell bodies are located in the brainstem or grey matter of S2-S4.2. Long preganglionic axons leave the spinal cord and travel to parasympathetic ganglion near target organ.3. They synapse onto 2-5 short, cholinergic (acetylcholine) postganglionic neurons that innervate the target organ (typically the axons are embedded in the target organ).
