The postganglionic neurons of sympathetic system are androgenic. This means these neurons use adrenaline, noradrenaline as the neurotransmitters. The postganglionic neurons of parasympathetic are cholinergic similar to preganglionic neurons. Sympathetic postganglionic neurons in paravertebral ganglia send their axons in two general directions.

By contrast, postganglionic fibers in the parasympathetic division are cholinergic and use acetylcholine as a neurotransmitter. Postganglionic fibers provide sympathetic innervation to kidneys, urinary bladder, terminal segments of large intestine, sex organs. Modified sympathetic ganglion at center of each adrenal gland.
