Epithelium Tissue

Dr. Farabee wrote in his article, the functions of the Epithelium tissue is to line, protect, and form glands. Epithelium can consist of three different cell types.These include: squamous epithelium, which are flattened cells, cuboidal epithelium, which are cube shaped cells, and finally, columnar epithelium, which are elongated cells. Epithelium can be simple stratified or psuedostratified. Simple has only one layer of cells while stratified has many layers of cells. And psuedostratified has only one layer but it appears, at first sight, to have two layers.
