Question

Which of the following hormone is produced by Cortex of adrenal gland?

• A. Norepinephrine
• B. Glucocorticoids
• C. Epinephrine
• D. Catecholamine

Hint:

Adrenal cortex → steroids (mineralocorticoids, glucocorticoids, androgens). Adrenal medulla → catecholamines.

Answer 1

The Correct Option is B

Step 1: Structure of adrenal gland.
The adrenal gland has two main parts: cortex (outer layer) and medulla (inner part).
Step 2: Hormones secreted.
- Adrenal cortex secretes steroid hormones:
• Mineralocorticoids (e.g., aldosterone)
• Glucocorticoids (e.g., cortisol)
• Androgens (sex steroids)
- Adrenal medulla secretes catecholamines (epinephrine and norepinephrine).
Step 3: Analysis of options.
- (A) Norepinephrine: Produced by adrenal medulla, not cortex.
- (B) Glucocorticoids: Correct, produced by adrenal cortex.
- (C) Epinephrine: Also produced by adrenal medulla.
- (D) Catecholamine: Group secreted by adrenal medulla, not cortex.
Step 4: Conclusion.
The adrenal cortex produces glucocorticoids.
