Quizplus · Accepted Answer

The ventromedial hypothalamus is associated with the regulation of appetite and body weight. Leptin, a hormone produced by fat cells, signals to the hypothalamus to suppress appetite and increase energy expenditure. In obese-prone rats, the cells in this area don't grow much (indicating a lack of responsiveness) and are less sensitive to leptin, which could contribute to their tendency to become obese.
