What neurotransmitter is released at the preganglionic synapses of the sympathetic division? What neurotransmitter is released at the postganglionic synapses of the sympathetic division?

All preganglionic nerves in Autonomic are cholinergic (use ACh – acetylcholine). All postganglionic nerves of parasympathetic ANS are cholinergic as well (use ACh). All postganglionic nerves of sympathetic ANS are noradrenergic (use NorEpi – Norepinephrine). For Sympathietic NS main neurotransmitter used is acetylcholine (Ex: muscular contraction).
