Question

Consider the following statements: Assertion (A): The hormone inhibin is secreted by the Sertoli cells. Reason (R): It enhances the secretion of follicle stimulating hormone.

• A. Both (A) and (R) are correct, (R) is the correct explanation of (A)
• B. Both (A) and (R) are correct, (R) is not the correct explanation of (A)
• C. (A) is correct, but (R) is not correct
• D. (A) is not correct, but (R) is correct

Hint:

Sertoli cells secrete inhibin, which suppresses FSH secretion through negative feedback regulation.

Answer 1

The Correct Option is C

Concept: Sertoli cells are supporting cells present inside seminiferous tubules of the testes. They play an important role in nourishment of developing sperm cells and hormonal regulation of spermatogenesis.

Step 1: Analyze the Assertion. Sertoli cells secrete the hormone inhibin. Inhibin participates in the feedback regulation of reproductive hormones. Therefore Assertion (A) is correct.

Step 2: Analyze the Reason. The reason states that inhibin enhances secretion of FSH. This is incorrect. Inhibin exerts negative feedback on the anterior pituitary and inhibits the secretion of follicle stimulating hormone (FSH). Therefore Reason (R) is false.

Step 3: Final conclusion. Assertion is true but Reason is false. \[ \boxed{\text{Assertion is correct, but Reason is not correct}} \] Hence option (C) is correct.
