Final answer:
Hunger pangs are controlled by the nervous system through various physiological mechanisms.
Step-by-step explanation:
Hunger pangs, which are the sensation of hunger, are controlled by the nervous system. The brain, specifically the hypothalamus region, is responsible for regulating hunger and satiety. When the stomach is empty, it contracts, causing hunger pangs.
Chemical messages then travel to the brain, initiating feeding behavior. On the other hand, when blood glucose levels increase, signals from the pancreas and liver shut off hunger and eating.
In addition, fat cells release leptin, a hormone that promotes satiety. Therefore, hunger and satiety are regulated by various physiological mechanisms influenced by neural and hormonal responses within the nervous system.
