Question

15
133. Identify the correct statement on 'inhibin':
(1) Inhibits the secretion of LH, FSH and
Prolactin.
(2) Is produced by granulose cells in ovary and
inhibits the secretion of FSH.
(3) Is produced by granulose cells in ovary and
inhibits the secretion of LH.
(4) Is produced by nurse cells in testes and
inhibits the secretion of LH.​

Answer 1

ANSWER

SOMETHING YOU NEED TO KNOW FIRST

• Inhibin, hormone is secreted by the granulosa cells in the ovaries of women.
• Granulosa cells are believed to originate from the ovarian surface.
• They inhibit the secretion of follicle-stimulating hormone by the anterior pituitary gland.
• FSH is present in the reproductive system.
• They regulate the reproductive processes in the body.

Therefore option 2) is your answer:

Is produced by granulose cells in ovary and

inhibits the secretion of FSH.

                                                                   

Answer 2

Ánswer :

2) Inhibin is produced by granulose cells in ovary and inhibits the secretion of FsH.

Explanation:

Inhibin is a peptide Hormone .

• Inhibin -A , which is secreted by granulosa cells of the ovarian follicles.
• Inhibin-B , is a testicular peptide, secreted by setroli cells .

Functions:

Inhibin -B

• It inhibits the release of GnRH and FSH, which will cause spermatogenesis to slow down.
• It controls FSH secretion via a negative feedback mechanism.

Inhibin-A

• It inhibit the production of follicle-stimulating hormone (FSH) by the pituitary gland.
• Inhibin- A is made by the placenta during pregnancy.
• The level of inhibin A in the blood is used in a maternal serum quadruple screening test.
