Question
After being cleaved from POMC in the ventromedial nucleus, alpha-MSH binds to MC4R-expressing neurons to suppress this phenomenon. For 10 points each:
[10m] Name this phenomenon primarily controlled by the arcuate nucleus. It doesn’t involve the circadian rhythm, but other factors that regulate this phenomenon include CART, NPY, ghrelin, and leptin.
ANSWER: appetite [or hunger; accept food intake or eating or feeding]
[10e] The arcuate nucleus is found in the tuberal region of this neurohormone-secreting brain structure. Connections between this brain structure and the pituitary gland link the endocrine and nervous systems.
ANSWER: hypothalamus [reject “thalamus”]
[10h] AgRP neurons promote appetite by secreting NPY and a “related peptide” given this name. Obesity and yellow coat color are observed in dominant mutations of an allele with this name in a classic example of epistasis.
ANSWER: agouti [or Agouti-related protein; accept Agouti-signalling protein]
