Question:

Aldosterone is released from which of the following Adrenal Cortical layers?

A. The zona glomerulosa.

B. The zona fasciculata.,

C. The zona reticularis.

D. All of the above are correct.

The Effects of Aldosterone:

Aldosterone is a steroid hormone and controls the blood electrolyte levels in the body. Aldosterone increases blood levels of sodium and water and decreases blood levels of potassium. Hypersecretion of aldosterone results in hypokalemia and alkalosis and inhibits neural and muscular activity.

Answer and Explanation:

The correct answer is A. The zona glomerulosa. Aldosterone is released from the zona glomerulosa layer of the adrenal cortex.

Aldosterone is the most important mineralocorticoid secreted by the zona glomerulosa layer of the adrenal cortex, which is the outer portion of the adrenal glands. 95% of the mineralocorticoid activity in the human body is due to aldosterone.
