How is satiety triggered?
What will be an ideal response?
Satiety is triggered in the ventromedial nucleus in response to a variety of physiological cues. After a meal, the stomach becomes distended, sending signals from stretch receptors in the lining of the stomach to the brain to suppress hunger. As protein, fatty acids, and monosaccharides reach the small intestine, two hormones, cholecystokinin and peptide YY, are released, sending feedback to the hypothalamus to increase satiety and decrease hunger. Once these nutrients are absorbed, the hormone insulin is released, which also results in a decrease in hunger, and the feeling of satiety.
