You have acetylcholine liberated at ganglion in both sympathetic and parasympathetic nervous system. You have noradrenaline secreted at post ganglionic sympathetic nerve terminals. You have acetylcholine secreted at post ganglionic parasympathetic nerve terminals.
The parasympathetic and sympathetic systems are branches of the autonomic nervous system.
The effects of the sympathetic nervous system are essential opposite those of the parasympathetic nervous system. The sympathetic nervous system accelerates functions such as heart rate and breathing and the parasympathetic slows these bodily processes down. The sympathetic also inhibits digestion, whereas the parasympathetic stimulates digestion. The sympathetic nervous system produces "fight-or-flight" reactions, while the parasympathetic functions under relaxed conditions.
