Quizplus · Accepted Answer

The layer of the blood vessel that is innervated by sympathetic vasomotor fibers is the tunica media. This layer is responsible for regulating the diameter of the blood vessel and blood flow through it. Sympathetic stimulation causes the smooth muscle cells in the tunica media to contract, leading to vasoconstriction and a decrease in blood flow.
