Simple cuboidal epithelium
The ovary is covered by a simple cuboidal epithelium, composed of a single row of cube-shaped cells. The nuclei of cuboidal cells are usually spherical, reflecting the equal height and width dimensions of these cells. This is one of the few examples of a simple cuboidal epithelium that is not lining a tubular structure. 400x, 1000x
