The neurotransmitters of postganglionic fibers differ: • In the parasympathetic division, neurons are cholinergic. That is to say acetylcholine is the primary neurotransmitter responsible for the communication between neurons on the parasympathetic pathway. • In the sympathetic division, neurons are mostly adrenergic (that is, epinephrine and norepinephrine function as the primary neurotransmitters). Notable exceptions to this rule includ… WebYour parasympathetic nervous system is a network of nerves that relaxes your body after periods of stress or danger.
