So Tunica Intima.

Tunica is a town in Tunica County, Mississippi, near the Mississippi River.

It lies between the tunica intima on the inside and the tunica externa on the outside.

The tunicae of blood vessels are three layers an inner layer (the tunica intima), a middle layer (the tunica media), and an outer layer (the tunica adventitia).

The tunica media (New Latin middle coat ), or media for short, is the middle tunica (layer) of an artery or vein.

And veins have a tunica externa a third layer.

And this is called the tunica externa. For external layer.

The dose of radiation to the conjunctiva is controlled by the time that the plaque is left in contact with the surface.

So the tunica externa has the blood vessels and it also has nerve endings.

But nerve endings actually can be in that layer. In that tunica externa layer.

So this would be muscle and this would be the layer called tunica media, or middle.

And together the basement membrane and endothelial cells, they make up a layer called the Tunica Intima.

And that's kind of the word we use because tunica comes from the word for coat or cloak.

And you also have a smooth muscle layer so kind of a red line to represent tunica media.

The tunica media may (especially in arteries) be rich in vascular smooth muscle, which controls the caliber of the vessel.

The third stage of syphilis also manifests as aneurysm of the aorta, which is due to loss of the vasa vasorum in the tunica adventitia.

So let's say you have a vein. On the inside it has that tunica intima layer and I'm not going to draw all of the cells out because now you know what that represents.

And the really interesting thing about the tunica externa is that you actually, on the large vessels, you find that they need blood to supply themselves, so some of these large vessels have little blood vessels on them.
