Question

Sertoli cells are found in
A. Ovaries and secrete progesterone
B. Adrenal cortex and secrete adrenaline
C. Seminiferous tubule and provide nutrition to germ cells
D. Pancreas and secrete cholecystokinin

Answer 1

Hint: Testis is the primary sex organ in males. Testis consists of seminiferous tubules which contain the sertoli cells. These are the special types of epithelial cells found in male reproductive system. They provide nutrition to the growing sperms in the testis.

Complete Answer:
The process of producing new organisms from the parents is known as reproduction. There are two types of reproduction: sexual and asexual reproduction. Humans show sexual mode of reproduction where two parents are involved. The male reproductive system includes testes, scrotum, spermatic ducts, sex glands, and penis.
Penis: It involves three cylindrical spaces of erectile tissue. The two which are larger, the corpora cavernosa lie side by side and the third one is sinus, called corpus spongiosum covering the urethra. The penis becomes rigid when these spaces are filled by the blood.

Scrotum: It is a sack of skin that protects and surrounds the testes. It also controls the temperature of the testes since they need to be at a rather lower temperature than the blood heat for suitable sperm creation. The muscles within the wall allow the testes to hold far away from the body or shrink to tug them closer for cover and heat.

Testes: They are the oval bodies, around 1.5 to 3 inches in length. The two primary functions of tests are producing testosterone which is a male sex hormone. And producing sperms which is the male gamete. It consists of various compartments known as testicular lobules. Each lobule contains highly coiled seminiferous tubules. They produce sperms and are lined by Sertoli cells.

So, the correct answer is option (C) which states that the Sertoli cells are present in seminiferous tubules.

Note: Ovaries are a part of the female reproductive system. They are the primary sex organs in females and release the sex hormones- progesterone and oestrogen. Adrenal cortex is an endocrine gland located on the top of kidneys in both males and females and it secretes the hormone called adrenaline. This hormone is also called fight or flight hormone. Pancreas is a mixed gland which secretes enzymes as well as hormones.
