Simple cuboidal epithelium is a single layer of cuboidal (cube-like) cells with large, spherical, and central nuclei. It is found on the ovaries, nephrons, renal tubule walls, eye, thyroid, and salivary glands.

Transitional epithelium, commonly known as urothelium, is a form of stratified epithelium that is found in the gastrointestinal tract. Stretching causes the transitional epithelium to alter shape (stretchable epithelium). When the transitional epithelium is relaxed, it appears cuboidal, and when it is stretched, it appears squamous.

Ciliated epithelium is a thin layer of tissue that is covered with hair-like features. These hairs, which are referred to as cilia, move back and forth to assist in the removal of particles from our bodies. It is found in women’s fallopian tubes and respiratory tract.
