Simple epithelia consist of only a single layer of cells. Squamous, cuboidal, columnar, and pseudostratified epithelium are the four types of simple epithelia. Squamous epithelium is made up of flattened cells, cuboidal epithelium is made up of a layer of cube shaped cells, columnar epithelium features a layer of cells in the shape of a pillar or column, and pseudostratified epithelium are made up of a single layer of pillar shaped cells that have the appearance of being multilayered. Stratified epithelia is made up of several layers of cells stacked on top of each other.
