Webb8 juni 2024 · The axons of the preganglionic neurons release acetylcholine on the postganglionic neurons, which are generally located very near the target organs. The parasympathetic nervous system resets organ function after the sympathetic nervous system is activated (the common adrenaline dump you feel after a ‘fight-or-flight’ event). WebbThe neurotransmitters of postganglionic fibers differ: In the parasympathetic division, neurons are cholinergic. That is to say acetylcholine is the primary neurotransmitter responsible for the …
