Detailed explanation-1: -Destruction of the ventromedial hypothalamus of a rat is most likely to: cause the rat to become extremely fat. An animal’s stomach and intestines will process food more rapidly and the animal will become extremely fat if its: ventromedial hypothalamus is destroyed.
Detailed explanation-2: -Damage to the Ventromedial Hypothalamus This lack of satiety causes excessive hunger, overeating and weight gain, leading to obesity. Scientists know this because of extensive research conducted on rats with a damaged ventromedial hypothalamus.
Detailed explanation-3: -VMH is the important center for satiety and adiposity and could be the ultimate pathway for control of food intake and obesity. The mechanism of hyperphagia as a cause of increased body weight after VMH lesion could be the possible mechanism for obesity.
Detailed explanation-4: -Electrical stimulation of the ventromedial hypothalamus enhances both fat utilization and metabolic rate that precede and parallel the inhibition of feeding behavior.
Detailed explanation-5: -Ventromedial hypothalamus (VMH) is designated as the principal satiety center governing feeding behavior. VMH is linked to the regulation of food intake and body weight in animals as well as humans. A lesion of VMH is found to cause obesity.
