The other three types are connective tissue, muscle tissue and nervous tissue. Epithelial tissues line the cavities and surfaces of blood vessels and organs throughout the body. There are three principal shapes of epithelial cells: squamous, columnar, and cuboidal.These can be arranged in a single layer of cells as simple epithelium, either squamous, columnar or cuboidal, or in layers of two or more cells deep as stratified (layered), either squamous, columnar or cuboidal.All glands are made up of epithelial cells.he lining of the esophagus is an example of a non-keratinized or moist stratified epithelium. Transitional. Transitional epithelia are found in tissues that stretch and it can appear to be stratified cuboidal when the tissue is not stretched or stratified squamous when the organ is distended and the tissue stretches.
EPITHELIUM â¢ epithelium is a tissue composed of a layer of cells.â¢ Epithelium lines both the outside (skin) and the inside cavities and lumen of bodies.â¢ The outermost layer of our skin is composed of dead stratified squamous epithelial cells, as are the mucous membranes lining the inside of mouths and body cavities.unctions of Epithelial Tissue â¢ Protection â¢Epithelial cells from the skin protect underlying tissue from mechanical injury, harmful chemicals, invading bacteria and from excessive loss of water. â¢ Sensation â¢Sensory stimuli penetrate specialised epithelial cells.
