1. The epithelium is a single layer of muscle in each person, some 60,000 miles long.

The innermost layer of the vein is the endothelial cells. Next layer is the smooth muscle cells. Final layer is connective tissue.
The brain endothelium is highly reactive because it serves as both a source of, and a target for, inflammatory proteins and reactive oxygen species. BBB breakdown thus leads to neuroinflammation and oxidative stress, which are implicated in the pathogenesis of CNS disease.
There are approximately 60,000 miles of blood vessels in an adult human body. This vast network of arteries, veins and capillaries is maintained and a protected by an inner sheath of microscopic cells called “endothelial” cells (from the Greek “endo” meaning within, and “thiele” meaning nipple, which together suggest “deep within our breast”). These many hundreds of thousands of cells, together comprising the “endothelium,” form the inner lining of blood vessels and lymph vessels, forming a thin layer between the vessel walls and the flowing blood, and serving as an interface between the blood and the rest or our body.
