The tunica interna of a muscular vein consists of an endothelium with a basal lamina, a thin subendothelial layer with smooth muscle cells, and a thin internal elastic membrane. Its tunica media has several layers of circularly arranged smooth muscle cells dispersed with collagen and elastic fibres. The smooth muscle cells may be arranged longitudinally in its tunica media. Its externa is generally thicker than its tunica media and has collagen fibres and a network of elastic fibres.
