Parasympathetic and sympathetic neural actions
What do you mean by the antagonism between parasympathetic and the sympathetic neural actions?
Expert
Generally, the actions of sympathetic and parasympathetic are antagonistic, that means whenever one stimulates something the other inhibits and vice versa. These organs, having few exceptions, get efferences from these two systems and from the antagonism between them which serves to modulate their effects. Such as, the parasympathetic stimulates salivation whereas the sympathetic reduces it; parasympathetic limits pupils whereas the sympathetic enlarges it; the parasympathetic contracts the bronchi whereas the sympathetic relaxes them; the parasympathetic excites the genital organs whereas the parasympathetic limits the excitation.
