block4_20.jpg - Fig.10 93W6515 Artery cs v&e. This slide is stained withVerhoeff's stain to visualize the elastic fibers, and with eosin toshow the cellular structures. Muscular arteries have moresmooth muscle and less elastin in the tunica media thanelastic arteries. The muscular arteries are characterized by alayer of internal elastic lamina separating the tunica intimafrom the tunica media. The less prominent and more variableexternal elastic lamina lies between the tunica media and theadventitia. The tunica intima consists of an endothelial liningand a small amount of connective tissue. However, nucleus ofthe endothelial cells can¡¦t be observed by the v&e stainingmethod. The tunica adventitia is composed of collagen fibers(pink), elastic fibers (black) and vasa vasorum.
