Medium (muscular) artery
These images demonstrate the three tunics of muscular arteries. The tunica intima possesses a prominent internal elastic lamina, separating it from the smooth muscle of the tunica media. The external elastic lamina is located at the junction of the tunica media and tunica adventitia. The tunica adventitia is composed mostly of collagenous connective tissue. The section of the vessel on the right was stained for elastin which particularly highlights the internal and external elastic laminae. 400x, 600x
