Question

multiple choice question
which nucleus, located in the hypothalamus, is an important brain center for appetite regulation?

red nucleus
pituitary
arcuate nucleus
optic nucleus

Explanation:

To solve this, we analyze each option:

• Red nucleus: In the midbrain, involved in motor control, not appetite regulation in hypothalamus.
• Pituitary: A gland connected to hypothalamus, not a nucleus within hypothalamus for appetite.
• Arcuate nucleus: Located in hypothalamus, key in appetite regulation (involved in feeding behavior, hormone signaling for hunger/satiety).
• Optic nucleus: Related to visual system, not in hypothalamus for appetite.

Answer:

C. Arcuate nucleus
