Which term describes the thick muscular layer of the arteries?

The thick muscular layer of arteries is the muscular wall, which is the middle layer of the arterial wall (the tunica media). This layer is rich in smooth muscle and elastic fibers, and its main job is to contract or relax to constrict or dilate the vessel, helping regulate blood flow and blood pressure. The lumen is the hollow passage inside the artery, not a layer. Chyle is a lymphatic fluid related to fat absorption, not part of arteries. The outer fibrous layer is a connective tissue sheath (adventitia) surrounding the vessel, not the thick muscular portion.
