Worksheet time: 5mins
Which hypothalamic nucleus acts as the satiety center?
Lateral nuclei
Ventromedial nuclei
Arcuate nucleus
Paraventricular nucleus
Destruction of the lateral hypothalamic feeding center leads to:
Hyperphagia
Inanition (severe weight loss)
Increased energy expenditure
Leptin resistance
Which hormone is known as the “hunger hormone”?
Leptin
Insulin
Ghrelin
Serotonin
What is the effect of stimulating the arcuate nucleus neurons that release α-MSH?
Increased food intake and decreased energy expenditure
Decreased food intake and increased energy expenditure
Increased appetite and weight gain

Ghrelin
Cortisol
Leptin
Peptide YY (PYY)
According to the glucostatic theory of hunger, what happens when blood glucose levels fall?
Satiety center is stimulated, leading to decreased food intake
Feeding center is stimulated, leading to increased food intake
Leptin levels rise, causing decreased appetite
Ghrelin secretion stops
Which gastrointestinal hormone is anorexigenic (appetite-suppressing)?
Orexin A
Peptide YY (PYY)
Ghrelin
Agouti-related peptide (AgRP)
What effect does exposure to cold temperatures have on food intake?
Decreases food intake
Increases food intake
No effect on food intake
Decreases metabolic rate
Which of the following statements about leptin resistance is TRUE?
It is common in underweight individuals
It leads to decreased appetite and weight loss
It is characterized by decreased sensitivity of leptin receptors
It results from low levels of leptin in obese individuals
