The nerves to the smooth muscle of all arteries and veins are:

Question

Quizplus · Accepted Answer

The sympathetic nervous system innervates the smooth muscle of both arteries and veins to regulate their diameter and thus blood flow. Parasympathetic nerves do not innervate the smooth muscle of blood vessels. Nerve tracts are bundles of nerve fibers that transmit information between different parts of the nervous system, but they do not directly innervate blood vessels. Visceral sensory nerves transmit information from internal organs to the central nervous system, but they also do not directly innervate blood vessels.
