Question

Germinal epithelium of the ovary has
(a) Cuboidal cells
(b) Columnar cells
(c) Squamous cells
(d) Stratified cells

Answer 1

Hint: The germinal epithelium of the ovary has cells that, during embryonic growth, are derived from the mesoderm and are closely connected to the peritoneum mesothelium. These cells are large and spherical. They contain central nuclei.

Complete step by step answer:
A layer of cuboidal epithelial cells covering the ovary is the ovarian surface epithelium, also known as Waldeyer's germinal epithelium. As it does not give rise to primary follicles, the term germinal epithelium is a misnomer.
The cuboidal epithelium forms the germinal epithelium of the ovary. In order to form the secretory and duct portions of glands, the simple cuboidal epithelium is generally distinguished. They also form the germinal epithelium in the male testes, which covers the internal walls of the seminiferous tubules. In absorption and secretion, these cells provide some defense and function.
So, the correct answer is, ‘Cuboidal cells’.

Additional information: Compared to the sparkling smoothness of the peritoneum, the germinal epithelium gives the ovary a dull grey color; and the transition between the peritoneum mesothelium and the cuboidal cells covering the ovary is usually marked by a line along the ovary's anterior edge. The surface epithelium of the ovary will give rise to an epithelial-stromal surface tumor.
The cuboidal cells provide protection and may be dependent on the location and cellular specialization, they can be active (pumping material in or out of the lumen) or inactive.

Note: A type of epithelium that consists of a single layer of cuboidal (cube-like) cells is a simple cuboidal epithelium. On the surface of the ovaries, the lining of nephrons, the walls of the renal tubules, and portions of the eye and thyroid, these cuboidal simple cuboidal epithelia are found.
In order to form the secretory and duct portions of glands, the simple cuboidal epithelium is commonly differentiated. They play a role in absorption and secretion.
