L19 Hypothalamus: Feeding

Question 1

1. What regions of the brain control feeding and satiety?

Answer 1

• lateral hypothalamus = feeding
• ventromedial hypothalamus = satiety

Question 2

2. Which of the following hypothalamic neuropeptides that regulate feeding is NOT found in the arcuate nucleus?

• Neuropeptide Y
• Cocaine- and Amphetamine-regulated transcript
• Melanin-concentrating hormone
• Agouti-related peptide

Answer 2

Correct: Melanin-concentrating hormone

There are 6 hypothalamic peptides that regulate feeding. Four of them are found in the arcuate nucleus (Neuropeptide Y, Cocaine- and amphetamine-regulated transcript (CART), Agouti-related peptide and alpha-Melanocyte-stimulating hormone (alpha-MSH)), and two in the lateral hypothalamus (orexin and Melanin-concentrating hormone)
