Question

Which of the following endocrine glands functions under nervous control?

• A. Cortex of adrenal glands
• B. Medulla of adrenal glands
• C. Anterior pituitary glands
• D. None of the above

Answer 1

Answer: (B)

Medulla of adrenal glands

The adrenal medulla is a part of the sympathetic nervous system. The sympathetic nervous system and the adrenal medulla are collectively known as the sympathoadrenal system. The chromaffin granules contain the hormones of the adrenal medulla, which include dopamine, norepinephrine, and epinephrine. When stimulated by sympathetic nerve impulses, the chromaffin granules are released from the cells and the hormones enter the circulation. Thus, the adrenal medulla is a neurohormonal organ.

So, the correct answer is option B.
