Heredity And Hormones

IntroductionHuman behavior varies from individual to individual . The tendencies to commit crimes , be a good deal aggressive or to be more intelligent ar all indicators of human behavior . Biologically speaking , this behavioural out dos argon a direct gist of endocrines and genes . The relation surrounded by these two aspects shall be examined belowA line of work of the utilisation of genetic endowment and inner(a) secretionsWhile ductless glands guide exculpate defined roles without one s life conviction , genes , which chance on heredity , be responsive to the milieu and their role clear transmits with respect to the purlieu . It should be noted that heredity is not some sort of master puppet holding the string and controlling the environment . As a matter of numberrence , genes change or evolve based o n the environment pastce explaining the tenableness why things such(prenominal)(prenominal) as mutations and variations occur Therefore , the way heredity influences human behavior at one point in time may not necessarily be the identical way it does years to come Conversely , internal secretions be precise specific in reputation , their presence or absence may change exactly their role remains eer the same . For instance , the hormone insulin is always responsible for standard of glucose in the proboscis and this role flowerpotnot change irrespective of the environment (Dean and Copeland , 1999In relation to this argument , the environment affects the dumbness or secretion of hormones . However , the availability of genes and hence heredity occurs irrespective of this . It should be noted that the environment in this case refers to all the internal and external surroundings of the frame . This sensitivity to environmental changes forms the mainstay of the `princip le of the feedback tool . When the frame h! as been capacityed to an unusual situation that stimulates business within the pendent , then the top dog impart be stimulated to produce the hormone adrenaline . This hormone increases glucose concentration in the muscle tissues and prepares the body for flight .

When the subject decides to run away from the situation , he has been empowered through the actions of this hormone . On the other flip over when the subject has reached a safe destination , then the brain lolly producing this hormone and waits for the next scenario . The process of waiting for want of the hormone in to stimulate its secretion is ca lled the negative feedback mechanism . Genes are always present in certain concentrations disregardless of the environment (Van Holde and Mathews , 1990In relation to the above argument , one can change the way hormones affect their overall behavior because their concentration varies from time to time . This is not possible in heredity because genes are unchanged . For instance , one can pass weewee contraceptives in to suppress the actions of reproductive hormones such as progesterone . This subsequently affects the overall behavior of the individual because they are both pregnant or not . Similarly , it has been shown that exercise , a balanced diet and healthy living largely repay towards secretion of some life prolonging hormones . Such healthy individuals are more likely to depict positive behavioral traits such as less moodiness . Therefore , it is possible...If you want to get a full essay, order it on our website: OrderCustomPaper .com
