GENERAL HISTOLOGY

Detailed explanation-1: -Simple squamous epithelial cells are thin and flat (the thinnest of all epithelial cell-types), which allows them to have a large surface area that is exposed to the lumen on one side (the apical surface), and to the basement membrane (i.e. basal lamina ) on the other (the basolateral surface; Figure 1).

Detailed explanation-2: -Squamous cells are thin and flat, just like the scales after which they are named. They provide a smooth surface that avoids blood turbulence in the blood vessels and also allows fluids to easily flow over them.

Detailed explanation-3: -A stratified squamous epithelium consists of squamous (flattened) epithelial cells arranged in layers upon a basal membrane. Only one layer is in contact with the basement membrane; the other layers adhere to one another to maintain structural integrity.

Detailed explanation-4: -These flattened cells are called endothelial cells . The nuclei are frequently found protruding into the lumen of the vessel. Observe the numerous large blood vessels present in the periphery of this section.

Detailed explanation-5: -Squamous cells are thin, flat cells that look like fish scales, and are found in the tissue that forms the surface of the skin, the lining of the hollow organs of the body, and the lining of the respiratory and digestive tracts.
