Sympathetic nervous system vs parasympathetic nervous system

Differences between Sympathetic and Parasympathetic

1. Anatomical: The location of preganglionic neurons of the autonomic ganglia and the extension of preganglionic and postganglionic fibers are different in these two systems;

2. Pharmacological: In the Sympathetic system we have the presence of Cholinergic fibers (Ach) and in the Parasympathetic system we have the presence of Noradrenergic fibers (NE);

3. Physiological: They act antagonistically, they rarely work harmoniously synergistically in coordinating visceral activity (balance)
