Question

Sertoli cells are found in
A. Kidney
B. Ovary
C. Liver
D. Testis

Answer 1

Hint: Sertoli cells are tall, simple columnar cells and are avascular in nature. The Sertoli cells work under the action of certain hormones to release specific chemicals. The most important and distinctive feature of the Sertoli cells is the presence of dark nucleolus.

Complete answer:
Sertoli are also referred to as the nurse or mother cells and are the epithelium supporting cells. The Sertoli cells are cells of the columnar epithelium and span from the basement to the lumen. Sertoli cells are found in the testis. The Sertoli cells are a type of sustentacular cells present in the testicle as a part of the seminiferous tubules. It is associated with the process of spermatogenesis. The Sertoli cells line the tubules and they help to develop the growing sperm cells. They are spermatogenic cells and differentiate through meiosis into sperm cells.
The development of male sex is dependent on the Sertoli cells. After differentiation and proliferation, the Sertoli cells cannot divide or proliferate. As a result, after initiation of the process of spermatogenesis, the Sertoli cells cannot proliferate further. They are activated by the follicle-stimulating hormone of the anterior pituitary gland. These cells bear FSH receptors on its cell membrane.
Certain types of conformational changes in the lateral border of the Sertoli cells are responsible for the movement cells into the lumen of the seminiferous tubules. The Sertoli cells are specifically located in the convoluted seminiferous tubules as it is the site where spermatozoa are formed. The prime function of the Sertoli cells is to nourish the cells developing as the sperm cells through the process of spermatogenesis. Due to their function of nourishing the sperm cells, they are known as mother cells or nurse cells. They also remove the cytoplasmic residue during spermatogenesis and are also referred to as phagocytes.
The Sertoli cells are an important cell of the testes which is the male reproductive organ. It is not found in the ovary which is the female reproductive organ and produces ova.
The kidneys are organs related to the excretory system and consist of cells that are known as nephrons. Seminiferous tubules are not found in kidneys.
The liver cells are known as the hepatic cells and are associated with metabolism of fats and protein and also store some vitamins and minerals. They do not consist of Sertoli cells.

Therefore, the correct option is option D.

Note: Sertoli cells are found associated with the process of providing nutrition and sustenance to the growing sperm cells present in the seminiferous tubules of the testis. They operate under the influence of FSH or follicle stimulating hormones.
