Question

\_\_\_\_\_\_\_ in the forebrain and vagus nerve play an important role in carrying signals of hunger to the brain:

• A. Insulin
• B. Leptin
• C. Ghrelin
• D. Adrenaline

Hint:

Ghrelin stimulates hunger by sending signals to the brain to promote appetite.

Answer 1

The Correct Option is C

Step 1: Role of Ghrelin.
Ghrelin, often referred to as the "hunger hormone," is produced in the stomach and plays a key role in stimulating appetite by sending hunger signals to the brain. Step 2: Other Hormones.
Insulin helps regulate blood sugar levels and is not involved in hunger signaling. Leptin signals satiety or fullness, reducing hunger. Adrenaline is involved in the body's fight or flight response, not in hunger regulation. Step 3: Conclusion.
Thus, ghrelin in the forebrain and vagus nerve plays an important role in carrying signals of hunger to the brain.
