Verified

In general actions of sympathetic and parasympathetic are antagonistic, that is, while one stimulates something the other inhibits and vice versa. The organs, with little exclusion, acquire efferences from these two systems and antagonism between them serves to modulate their effects. For illustration, parasympathetic stimulates salivation while sympathetic inhibits it; parasympathetic constricts pupils while sympathetic dilates it; parasympathetic contracts bronchus while sympathetic relaxes them; parasympathetic excites genital organs while parasympathetic inhibits the excitation.
