One role of the ventromedial hypothalamus may be to

• A. release the hormone leptin when blood sugar levels are stabilized.
• B. regulate the basal metabolic rate to control weight set point.
• C. stop the eating response when glucose levels go up.
• D. influence the onset of eating when insulin levels go up.

Answer: (C)

Verified step by step guidance

1. Begin by understanding the function of the ventromedial hypothalamus (VMH) in the brain. The VMH is involved in regulating hunger and satiety signals.
2. Consider the role of glucose levels in the body. When glucose levels rise, it typically signals that the body has received enough energy from food, which can trigger satiety signals.
3. Explore how the VMH interacts with glucose levels. The VMH is known to respond to changes in glucose levels, particularly by stopping the eating response when glucose levels are sufficiently high.
4. Examine the relationship between insulin levels and eating behavior. Insulin is a hormone that helps regulate blood sugar levels, and its increase can signal the body to start eating.
5. Conclude by identifying the correct function of the VMH in the context of the given options. The VMH stops the eating response when glucose levels go up, indicating its role in satiety and energy balance.
