The section of the vessel on the right was stained The tunica intima is a thin layer composed of a simple squamous epithelium known as endothelium and a small amount of connective tissue. Abstract To determine borderline values of intima-media thickness (IMT) of the common carotid arteries (CCA) in Moscow citizens without clinical symptoms of atherosclerosis. In blood vessels the simple squamous lining cells (epithelium) is called the endothelium.These are medium-sized veins with the three vascular layers well defined (tunica intima, tunica media, and tunica externa or adventitia) and diameters between 1 and 5 mm (Figures 1 and and2) 2) (16,17).

Since this perception is very persistent in It is known that in inflammatory arterial diseases, the tunica media is less infiltrated by inflammatory cells than the tunica intima and tunica adventitia because passive mechanical and active biological mechanisms protect it—tunica media is immunoprivileged . endothelium is continuous with endocardial lining of heart. The atherosclerotic process starts at the tunica intima and tunica media layer in the arterial wall and causes a structural change in the early period as increased intima-media thickness (IMT). Year introduced: 1993. These cells allow fluid to flow smoothly and are interspersed with valves that ensure the flow continues in one direction.
