Biological Explanations to Eating Behaviour

We sweep away to survive however when and how much we eat depends on metabolism which is regulated by several biological mechanisms. These mechanisms cinch to keep nthe ody in homeostasis. The set distributor point escape argues we open a biologically determined standard aroiund which our torso free incubus is regulated, so if we eat in desire manner much or too little our homeostatic mechanisms alter our metabolism accordingly to fuck offting even to our pilot burner exercising weight. However consistent over take or below eating makes it difficult for these mechanisms to keepup and we enf up having a clean weight as our set point. The hypothalamus is the main area entang take in regulating our appetite. The side(prenominal) hypothalamus stirs hunger, the ventromedial hypothalamus trigers sense of feeling full, this is know as surfeit. Evidence for this comes from the fact that aggrieve to the hypothalamus results in drastic changes in food intake. Accord ing to the set point theory our weight is controlled by the balance between the twain parts of the hypothalamus. Researchers doscovered that damage to the lateral hypothalamus in rats leads to a tally called aphasia ( they did not eat ), whereas stimulation to the lateral hypothalamus leads to eating more. This suggests that the lateral hypothalamus is like the strike for eating and satiety.

Damage to the medial hypothalamus caused the rats to overeat, a condiotn known as hyphergia, whereas stimulation of the medial hypothalamus inhibited eating behaviour and led them to eating less. This suggests that the medial hypothalamus is responsible for eati! ng, devoted its range of glucose receptors. The mdeial hypothalamus has been seen as the satiety centre. However Gold et al argued that lesions to the medial hypothalamus all are not sufficient to produce changes in satiety. kinda only when lesions included the PVN did satiety behavious change. This suggests that the theory is reductionist as there are a issue of complex factors that final result eating and satiety not moreover the...If you want to get a full essay, order it on our website: OrderCustomPaper.com
