    Apical
    The surface of a cell that faces a lumen or an outside area.
    Basolateral
    The surfaces of a cell that faces away from a lumen or outside area.
    Cilia
    A organelle and cell modification that manifests as a membrane projection capable of movement.
    Cornification
    A layer of dead cells filled with keratin that form a protective barrier over a layer of cells. Seen with stratified squamous epithelium.
    Desmosomes
    A cell modification that is responsible a cell to cell adhesion resistant to shearing forces to the epithelial layer.
    Endothelium
    A type of simple squamous epithelium that lines in inside of vascular structures.
    Epithelium
    A basic tissue type that typically lines a surface (cavity, lumen or outside surface) or forms glands. plural, epithelia; adjective, epithelial

    A type of columnar epithelium in which the nuclei are arranged in different levels in the cell layer.
    Simple
    An unilayered arrangement of epithelial cells.
    Stratified
    A multilayered arrangement of epithelial cells.
    Tight junctions
    A cell modification that is responsible for cell to cell adhesion.
