Question

Consider the following statements:
Assertion (A): Hypothalamus is the master control centre of the endocrine system
Reason (R): Its secretions directly control the pituitary gland

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

Hint:

Remember: The hypothalamus-pituitary axis is central to endocrine regulation. Hypothalamus secretes releasing/inhibiting hormones → Pituitary secretes trophic hormones → Target glands respond. Always connect function with regulatory control.

Answer 1

The Correct Option is A

The hypothalamus regulates endocrine activities by secreting releasing and inhibiting hormones which act directly on the anterior pituitary. These hormones control secretion of pituitary hormones, making the hypothalamus the master control centre. Both Assertion and Reason are true and Reason correctly explains the Assertion.
