The coronary vessels are what type of artery?

Explanation:
The coronary vessels are medium-sized muscular arteries. They sit on the heart’s surface (epicardial arteries) and have a thick tunica media rich in smooth muscle, which lets them constrict or dilate to regulate blood flow to the myocardium. Elastic arteries (like the aorta) have many elastic lamellae to dampen pressure waves, while small arteries/arterioles are part of the microcirculation. The structure and function of the coronary arteries align with the muscular, medium-size category, making this the best fit.
