Which peptide hormone, secreted by endocrine cells in the small intestine and colon after a meal, acts on the arcuate nucleus to inhibit NPY release and reduce hunger?
Explanation
Short-term regulation of hunger is managed by hormones from the gastrointestinal tract. PYY3-36 is a satiety hormone released from the intestine and colon after eating, which signals the brain to reduce hunger by inhibiting appetite-stimulating neurons.
