Germinal epithelium of ovary is composed of

Answer. The germinal epithelium of ovary is composed of Cuboidal Epithelium. Thus, the correct answer is option C.

Complete Answer:

The surface of the ovary is covered by a single layer of cuboidal epithelial cells, known as the germinal epithelium. Despite what its name suggests, the germinal epithelium of the ovary does not produce germ cells (ova). In reality, germ cells originate from the yolk sac during embryonic development and later migrate to the developing gonads.

Function of Cuboidal Epithelium

The simple cuboidal epithelium that lines the surface of the ovary, also known as the ovarian surface epithelium, primarily serves as a protective covering for the organ. It maintains the integrity of the ovarian surface and plays an important role in repairing the tissue after ovulation, when the follicle ruptures to release an egg. Although this epithelial layer does not generate germ cells, its structural position and function are essential for the overall health and proper functioning of the ovary.

Reference to the Other Given Options

To understand why only ‘Cuboidal Epithelium’ is the correct answer, let us examine the other options provided in the question and see why they are not suitable as the correct type of tissue.

Option A. Columnar epithelium

Columnar epithelium is made up of tall, column-like cells. These cells are generally found lining organs such as the intestines, stomach, and parts of the respiratory tract, where absorption and secretion take place. However, the surface of the ovary is not lined with columnar cells, so this option does not correctly describe the structure of the germinal epithelium. Therefore, this option is incorrect.

Option B. Squamous epithelium

Squamous epithelium consists of flat, thin cells that are commonly found in the skin, mouth, and linings of body cavities. These cells protect areas exposed to wear and tear. But the ovarian surface is not composed of flat squamous cells. Since this does not match the actual structure of the germinal epithelium, this option is also incorrect.

Option D. Stratified epithelium

Stratified epithelium has multiple layers of cells, making it suitable for areas that undergo constant friction, such as the oesophagus and outer layer of the skin. In contrast, the germinal epithelium of the ovary consists of a single layer of cells, not multiple layers. So, this option does not fit the question and is incorrect.
