Question

Quizplus · Accepted Answer

The ventromedial hypothalamus plays an important role in signaling satiety, as damage to this area of the brain can result in hyperphagia (excessive eating) and obesity. A) Neuropeptide Y is actually a hunger-stimulating hormone, not a satiety signaling hormone. B) Cholecystokinin is actually released to signal satiety and a feeling of fullness, not to encourage us to eat. C) Leptin is released by fat cells, but its role is to signal the brain to reduce food intake and increase energy expenditure, not to signal the need to eat.
