|Description:||Magnified 1125X, this photomicrograph depicted some of the cytoarchitectural characteristics of a number of common epithelial cells.|
Epithelial cells are found covering the surfaces of the body, as well as the lining of vessels and cavities. Depending on the cellular morphology displayed by the cell various cell type, i.e., cuboidal, columnar, and squamous, as well as the number of layers in which the cells are arranged, i.e., a single layer, or multiple layers, epithelial cell types are named accordingly. As an example, a cuboid, i.e., square-shaped, cells arranged in more than one layer are known as stratified cuboidal epithelium. Whereas, single-layered, flattened cells, like those which comprise the inner-most layers of blood vessels, are known as simple squamous epithelial cells.
