GENERAL HISTOLOGY

Detailed explanation-1: -Based on the cell shape, epithelial tissue is classified into squamous, cuboidal or columnar. Depending on the number of layers, the tissue is divided into simple or stratified. Subclassifications include pseudostratified, ciliated or transitional. Glandular epithelial cells produce and release various macromolecules.

Detailed explanation-2: -Types of epithelial cells based on their shape Different types of epithelial cells based on shape include: Squamous epithelium: Squamous epithelial cells are flat and sheet-like in appearance. Cuboidal epithelium: Cuboidal epithelial cells are cube-like in appearance, meaning they have equal width, height and depth.

Detailed explanation-3: -When epithelium is stratified, it is classified by the shape of the cells at the top or uppermost layer. A notable exception is pseudostratified epithelium. In this type of epithelium, taller simple columnar epithelial cells appear to have several nuclei at different heights, giving the appearance of stratification.

Detailed explanation-4: -Most epithelial tissue is described with two names. The first name describes the number of cell layers present and the second describes the shape of the cells. For example, simple squamous epithelial tissue describes a single layer of cells that are flat and scale-like in shape.

Detailed explanation-5: -Epithelial cells come in different shapes depending on where in the body they’re found. These shapes are called squamous, cuboidal, columnar, and ciliated columnar. Squamous epithelial cells are flat and are usually found lining surfaces that require a smooth flow of fluid, such as your blood vessels.
