Medium (muscular) artery
The innermost tunica intima of a muscular artery displays a prominent internal elastic lamina, consisting of a single, fenestrated, elastic sheet. The thick tunica media is composed of circularly arranged smooth muscle. An external elastic lamina, composed of elastic sheets, separates the tunica media from the outermost connective tissue layer, the tunica adventitia. 100x
