General Microscopic Description
Large and small arteries, <1cm in diameter have 3
layers, intima, media, and adventitia.
Intima is thin and includes the endothelium, an
underlying thin layer of connective tissue containing
smooth muscle. An elastic fiber layer, the elastica
interna, demarcates the intima from the media.
Media is thickest layer and is made up of smooth
muscle and collagen fibers. Larger arteries may contain
some elastic fibers.
Adventitia is sharply demarcated from the smooth
muscular media, and is a thin layer containing elastic
fibers in an loose connective tissue.
