Verified step by step guidance

Understand the structure of blood vessels: Arteries have three main layers - the tunica intima, tunica media, and tunica externa.

Identify the role of the tunica media: This is the middle layer of the artery wall, primarily composed of smooth muscle and elastic fibers.

Differentiate between types of arteries: Elastic arteries, also known as conducting arteries, have a high content of elastic fibers in the tunica media to accommodate the surge of blood from the heart.

Recognize the characteristic of muscular arteries: These arteries have a prominent elastic lamina on both sides of the tunica media, known as the internal and external elastic laminae, which distinguishes them from other types of arteries.

Conclude that the presence of an elastic lamina on both sides of the tunica media is a characteristic feature of muscular arteries, which helps them regulate blood flow by constricting or dilating.
