    simple columnar epithelium

    Tip: Dark band along apical edge= microvilli (increase surface area for absorption)

    pseudostratified columnar epithelium

    Tip: All cells reach to basement layer, but not all reach apical layer. Nuclei @ varying distances from apical border. Falsley stratified. Indentations are called goblet cells, and they secrete mucous into lumen (open area). Notice banding--this is the microvilli that is found in columnar epithelial cells.

    keratinized stratified squamous epithelium

    Tip: Can tell it is keratinized because of distinct layers. There are 5 OBVIOUS layers. Covers outer surfaces of body-- i.e. skin.

    Transitional Epithelium

    Tip: The circles are on the binucleated cells, which are characteristic of transitional epithelium. The test pointer will likely be right on a binucleated cells.
