Function of autonomic nervous system A.Functions of the sympathetic system stimulation of sympathetic nerve produces mydriasis, skin, splanchnic vessels contract, increase in blood pressure, heart rate accelerates, positive inotropic, positive chronotropic, visceral smooth muscle relaxes B. Functions of the parasympathetic system stimulation of parasympathetic nerve acts to oppose or balance the actions of the sympathetic system, it produces miosis, visceral smooth muscle contracts, stimulates intestinal secretions and motility tract, decrease in heart rate and cardiac output, et
