Question

Which one of the following hormones is produced by the adrenal gland?

• A. Thyroxine
• B. Cortisol
• C. Insulin
• D. Melatonin

Hint:

Adrenal cortex → Cortisol, Aldosterone; Adrenal medulla → Adrenaline, Noradrenaline.

Answer 1

The Correct Option is B

Step 1: Recall adrenal gland hormones.
The adrenal glands consist of two parts: adrenal cortex and adrenal medulla.
- The adrenal cortex secretes cortisol, aldosterone, and androgens.
- The adrenal medulla secretes adrenaline and noradrenaline.
Step 2: Evaluate options.
- Thyroxine: Produced by the thyroid gland, not adrenal.
- Cortisol: A glucocorticoid hormone secreted by the adrenal cortex. Correct.
- Insulin: Produced by the pancreas (beta cells).
- Melatonin: Produced by the pineal gland.
Step 3: Conclusion.
Hence, cortisol is the hormone secreted by the adrenal gland.
Final Answer: \[ \boxed{\text{Cortisol is produced by the adrenal gland.}} \]
