block4_18.jpg - Fig.9 93W4875 Trachea and esophagus cs h&e. Note theelastic artery in the slide. The characteristics of the elasticarteries described in figure 5. However, the elastic lamellaeare fewer and not so obvious than the lamellae in aorta. Thecollagen fibers and smooth muscle cells are more in the tunicamedia in this artery. The tunica intima consists of a singlelayer of endothelial cells. The tunica adventitia is theoutermost part. It consists mainly of connective tissue andcontains the blood vessels (vasa vasorum) that supply thearterial wall.
