Which adrenal cortex layer synthesizes cortisol?

Explanation:
Cortisol is a glucocorticoid produced by the adrenal cortex, and the cortex has three distinct layers each making different steroids. The middle layer, the zona fasciculata, is specialized for glucocorticoid synthesis and is stimulated by ACTH to increase cortisol production. The outer layer, zona glomerulosa, makes mineralocorticoids like aldosterone, while the inner layer, zona reticularis, produces adrenal androgens. The adrenal medulla (not part of the cortex) secretes catecholamines. Therefore, the layer responsible for synthesizing cortisol is the zona fasciculata.
