Question

Which of the following option is correct for the secretion of the adrenal cortex?
(i) Mineralocorticoids are secreted by Zona Fasciulata.
(ii) Zona Glomerulosa regulates the balance of water and Na${}^{+2}$.
(iii) Sex corticoids are secreted by both Zona Fasciculata and Zona Reticularis.
(iv) Zona Glomerulosa regulates carbohydrate, protein and fat metabolism.

• A. (ii), (iii)
• B. (i), (iv)
• C. (ii), (iv)
• D. (i), (iii), (iv)

Answer 1

The correct option is A (ii), (iii)

Glucocorticoids are secreted by Zona fasciculata. Mineralocorticoids are secreted by the Zona glomerulosa of the adrenal cortex.Zona glomerulosa is the outermost layer of the adrenal cortex. The hormone regulates electrolyte balance. It regulates the balance of water and Na${}^{+2}$ ions. Zona reticularis secretes androgens like dehydroepiandrosterone (DHEA) and androstenedione.

Thus, the correct answer is '(ii), (iii).'
