Eight types of epithelial tissue

First name of tissue indicates number of cell layers

Simple—one layer of cells
Stratified—more than one layer of cells

Last name of tissue describes shape of cells

Squamous—cells are wider than tall (plate-like) – “squashed”
Cuboidal—cells are as wide as tall, like cubes
Columnar—cells are taller than they are wide, like columns

simple squamous epithelium — In this example we see air sacs of lungs

simple cuboidal epithelium — We find these types of cells in kidney tubules.

simple columnar epithelium — Found in most of the digestive tract, like the stomach

pseudostratified ciliated columnar epithelium — Found in the trachea (just remember cilia pushes mucus up, in the trachea)

stratified squamous epithelium — Nonkeratinized forms in all places mucous membranes are found

stratified cuboidal epithelium — Saliva, sweat and mammary glands all have these cuboidal stratified tissue

stratified columnar epithelium — Very rare, found in male urethra and large ducts of some glands.

transitional epithelium — Everything urine-related because it stretches (transitions) with pressure.
