The layer of the arteriole wall that can produce vasoconstriction is the tunica

Question

Quizplus · Accepted Answer

The media layer of the arteriole wall contains smooth muscle cells that can contract and produce vasoconstriction, reducing blood flow in the vessel. The adventitia (also known as the outermost layer or externa) provides structural support but does not have the ability to produce vasoconstriction. The intima (or innermost layer) is composed of endothelial cells that form a smooth lining for the vessel, but do not have the contractile ability of the media layer. The terms "e-mater" are not familiar or relevant in this context.
