Locate a large fingerlike projection at the surface of the organ (this is an intestinal villus ). Observe that the projection has an internal component and a surface. The surface of each villus is covered with simple columnar epithelium .
Epithelial tissue which is only one cell thick is known as simple epithelium. If it is two or more cells thick such as the skin, it is known as stratified epithelium. Simple epithelium Simple epithelium can be subdivided according to the shape and function of its cells.Squamous (pavement) epithelium.Squamous cells have the appearance of thin, flat plates. The shape of the nucleus usually corresponds to the cell form and help to identify the type of epithelium.olumnar epithelium forms the lining of the stomach and intestines. Some columnar cells are specialised for sensory reception such as in the nose, ears and the taste buds of the tongue. Goblet cells (unicellular glands) are found between the columnar epithelial cells of the duodenum.
