Vhich of the following is an inaccurate description of autonomic innervation of the cardiovascular ystem? A) Both sympathetic and parasympathetic neurons innervate the SA and AV nodes. B) Only sympathetic neurons provide significant innervation of the contractile cells of the heart. C) Only sympathetic neurons innervate smooth muscle in veins. D) Sympathetic activity increases cardiac output, whereas parasympathetic activity decreases cardiac output. E) Both sympathetic and parasympathetic neurons innervate smooth muscle in arterioles.
