context_page_description: Simple cuboidal epithelium is a type of epithelium that 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.
  On these surfaces, the cells perform secretion and absorption.
context_section_description: These cells provide protection and may be active (pumping material in or out of the lumen) or passive, depending on the location and cellular specialization.
  Simple cuboidal epithelium commonly differentiates to form the secretory and duct portions of glands.  They also constitute the germinal epithelium which covers the ovary (but does not contribute to ovum production) and the internal walls of the seminiferous tubules in the male testes. These cells offer some protection and function in absorption and secretion.
