Answer 1

@PRAETORIAN.10

Answer 2

"Tunica intima is made up of an epithelium, which is a single layer of flattened epithelial cells, together with a supporting layer of elastin rich collagen. This layer also has fibroblasts and 'myointimal cells' that accumulate lipid with ageing, and the intima layer thickens, one of the first signs of atherosclerosis."

Answer 3

"The tunica intima is composed of a lining layer of highly specialized multifunctional flattened epithelial cells termed endothelium. This sits on a basal lamina; beneath this is a very thin subendothelial layer of fibrocollagenous support tissue containing occasional contractile cells with some of the properties of smooth muscle cells but which are also capable of synthesizing collagen and elastin (like fibroblasts) and which also can have phagocytic properties .... These cells are called myointimal cells and become very important in the development of the most common arterial disease, atheroma."
