The simple cuboidal epithelium is a special type of epithelium composed of a single layer of cuboidal (cube-like) cells with enormous, spherical nuclei.
On the surface of the ovaries, the lining of nephrons, the walls of renal tubules, parts of the eye and thyroid, and salivary glands, the simple cuboidal epithelium can be seen.
Both secretion and absorption occur on these surfaces.
Location:
Simple cuboidal cells are also present in the tubules of nephrons, glandular ducts, and thyroid follicles in addition to renal tubules.
With their spherical nuclei in the middle, simple cuboidal cells are found in single rows and are immediately connected to the basal surface.
Simple cuboidal cells with cilia are also seen in the respiratory bronchioles.
Germinal cuboidal epithelial cells border the testes' ovaries and seminiferous tubules.
