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

In this example we see air sacs of lungs

We find these types of cells in kidney tubules.

Found in most of the digestive tract, like the stomach

Found in the trachea (just remember cilia pushes mucus up, in the trachea)

Nonkeratinized forms in all places mucous membranes are found

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

Very rare, found in male urethra and large ducts of some glands.

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