Basement membrane is a delicate noncellular layer made of extracellular material that lies below the epithelium in contact with its basal surface. Basement membrane is a delicate noncellular layer made of extracellular material that lies below the epithelium in contact with its basal surface. Besides this the basal lamina consists of mucopoly saccharides and very fine fibres.

Correct Option: D

The simple cuboidal epithelium consists of a single layer of polygonal cells which appear cuboidal in vertical section. Cuboidal epithelium occurs in terminal respiratory bronchioles. Columnar epithelium is made of tall cylindrical cells and it occurs in the lining of stomach. In ciliated epithelium, the cells bear cilia on their free surface and it occurs in the respiratory tract.

Squamous epithelium is formed of thin discoidal and polygonal cells that fit like tiles in a floor, so is also called pavement epithelium. It is found in the walls of blood vessels, in the alveoli of lung for exchange of gas, and in Bowman’s capsule of nephron for ultra filtration.
