Both the brain and spinal cord receive signals from the afferent neurons and send signals to muscles and glands through efferent neurons.

What happens when the parasympathetic nervous system is activated?

Body functions stimulated by the parasympathetic nervous system (PSNS) include sexual arousal, salivation, lacrimation, urination, digestion, and defecation. The PSNS primarily uses acetylcholine as its neurotransmitter. Peptides (such as cholecystokinin) may also act on the PSNS as neurotransmitters.
