Large vein
The walls of large veins show great heterogeneity. Here, tunica intima is composed of endothelium and a CT layer that contains longitudinally orientated smooth muscle. A discontinuous internal elastic lamina is present. Tunica media is composed of circularly arranged smooth muscle (cut in cross section in this longitudinal section), interspersed with CT. 400x
