Definition: An epithelium is a close association of cells lacking notable amounts of intercellular substance.
Most epithelia cover inner or outer surfaces of organs or form glands. The aspect of the uppermost cells, order of cell nuclei and eventual presence of layers is the base for classification.
Classification and presence of epithelia:
