The stratified squamous epithelium is an avascular ( lacks blood vessels ) tissue in which germinative (basal) layer consists of cuboidal and columnar cells with … Epithelial tissue has a nerve supply, but no blood supply and must be nourished by substances diffusing from the blood vessels in the underlying tissue. For example, no blood vessel goes through the basement membrane to enter the tissue, and the nutrients must come by diffusion or absorption from the underlying tissues or surface. polarity of epithelial cells: Most of the epithelial cells polarise because of distinct morphological and biochemical characteristics which associate with different surfaces of these cells. The most basic characteristic of epithelial tissue is that it covers the surfaces of the body, whether external or internal. Epithelial tissues cover all external and internal surfaces of the body. Third, epithelial cells exhibit polarity with differences in structure and function between the exposed, or apical, facing cell surface and the basal surface closest to the underlying tissue.
