Question

Quizplus · Accepted Answer

The sympathetic nervous system innervates the ventricular myocardium, arteriolar smooth muscle, and venous smooth muscle, providing regulatory control over heart rate, contractility, and vascular tone. The parasympathetic nervous system does not innervate the ventricular myocardium or the smooth muscle of arteries and veins, focusing instead on areas like the SA and AV nodes for heart rate modulation.
