The tunica adventitia of connective tissue surrounds the tunica media, the latter is seen to consist of circularly-arranged smooth muscle cells.
The tunica media of the veins is meager and is limited to a thin layer peripheral to the internal elastic membrane.
The tunica media consisting of smooth muscle is meager in large veins, and is indicated by the pointer at "a".

 Blue Histology - Vascular System
Larger vessels are therefore accompanied by smaller blood vessels which supply the tunica adventitia and, in the largest vessels, the outer part of the tunica media of the vessel wall.
It is difficult to identify an external elastic lamina or to distinguish the tunica adventitia from the connective tissue surrounding the vessel.
The tunica media is, again as compared to the artery, very thin and there is no sharp border between the tunica media and the tunica adventitia.

 Laboratory Nine: Cardiovascular System
The outermost elastic lamina separates the tunica media from the adventitia and is called the external elastic lamia.
As a result of contraction, the tunica intima (with endothelium and inner elastic lamina) is typically thrown into deep folds, and the nuclei of the endothelial cells protrude into the vessel lumen.
In the vein, the adventitia layer is larger that the media.

 Exercise 12b
The tunica media is a region of elastic and collagen fibers.
This field is from the outer edge of the tunica media: the almost-completely red area at the bottom is the tunica adventitia.
Some elastic fibers and collagen fibers will always be present, but eventually the great bulk of the tunica media will be smooth muscle, and at that point we're dealing with muscular or distributing arteries, whose function is to "distribute" blood supply to their regions of responsibility, such as a limb.

Moreover, the influence of circulating hormones (epinephrine, norepinephrine, prostaglandins and plasma kinins) may be transmitted directly from endothelial cells to contractile elements, because specialized contact between these cells have been demonstrated.

Extending from the aortic valve to the diaphragm, the thoracic aorta is an elastic, stratified tube comprised of three layers: the tunica intima, tunica media, and tunica adventitia.
The tissue that served as the source of the A-10 cell line was part of the aorta's middle layer, also known as the tunica media.
In addition to smooth muscle cells, the tunica media contains an abundance of elastin fibers, which are important for propelling the blood through the aorta.
