Cuboidal epithelium
Simple cuboidal epithelium is a type of epithelial tissue that provides protection and mechanical support. It consists of a single layer of cuboidal cells. These cuboidal cells have large, spherical and central nuclei. Simple cuboidal epithelia are found on the surface of ovaries, the lining of nephrons, the walls of the renal tubules, and parts of the eye and thyroid gland.
