Q.Name the layers of adrenal cortex and mention their secretions.

Step 1. The adrenal cortex, the outer region of the adrenal gland, has three histologically distinct zones.

Step 2. The outermost zone, zona glomerulosa (about 15% of the cortex), secretes mineralocorticoids, which regulate mineral (salt/water) balance.

Step 3. The middle zone, zona fasciculata, the widest layer (about 75% of the cortex), secretes glucocorticoids such as cortisol and corticosterone, plus trace amounts of adrenal androgen and oestrogen. …

• Mixing up which zone secretes mineralocorticoids vs glucocorticoids, or forgetting that the innermost zona reticularis mainly secretes …
