What is the Difference Between Elastic Arteries and Muscular Arteries

Question

What is the difference between elastic arteries and muscular arteries?
A) Elastic arteries have more smooth muscle than muscular arteries.
B) Muscular arteries have larger lumens than elastic arteries.
C) Elastic arteries have elastic fibers throughout the tunica media whereas muscular arteries have few elastic fibers in the tunica media.
D) Elastic arteries are closest to the arterioles and muscular arteries are farther away.
E) Elastic arteries have a larger tunica intima and tunica media compared to muscular arteries.

Accepted Answer

Elastic arteries have a well-developed tunica media with elastic fibers throughout, providing elasticity needed for blood pressure regulation. In contrast, muscular arteries have a thicker layer of smooth muscle in the tunica media, which allows them to contract and regulate blood flow to specific organs or regions of the body.
