Epithelial tissues, also called epithelia, are tissues specialized in the covering of external and internal surfaces of the body.

The general function of the epithelium is to provide protection and impermeability (or selective permeability) to the covered structure. This justifies the epithelium's typical features: the cellular juxtaposition forming layers of very proximate cells with diminished or none intercellular space between each two neighbor cells.
