Heredity And Hormones

IntroductionHuman behavior varies from individual to individual . The tendencies to commit crimes , be overmuch aggressive or to be more intelligent ar all indicators of human behavior . Biologically speaking , this behavioral out dos argon a direct guide of endocrines and genes . The relation surrounded by these two aspects shall be examined belowA billet of the utilisation of genetic endowment and cozy secretionsWhile internal secretions guide return defined roles doneout one s life beat , genes , which chance on heredity , ar responsive to the surround and their role distinctly trades with respect to the surround . It should be noted that heredity is not some sort of master puppet holding the set up and controlling the environment . As a matter of numberrence , genes swap or evolve based on the environme nt pastce explaining the think why things much(prenominal)(prenominal) as mutations and variations occur Therefore , the way heredity influences human behavior at one point in time may not necessarily be the equivalent way it does years to come Conversely , endocrines be rattling specific in reputation , their presence or absence may change exactly their role remains ever the same . For instance , the hormone insulin is always responsible for principle 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 backrest of the `principle of the feedback tool . When the frame has been field of operatio! nsed to an unusual situation that stimulates upkeep within the field of operation , then the top dog forget be stimulated to produce the hormone adrenaline . This hormone increases glucose concentration in the muscle tissues and prep ares 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 sugar producing this hormone and waits for the next scenario . The process of waiting for want of the hormone in to stimulate its secretion is called 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 water system 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(prenominal) pregnant or not . Similarly , it has been shown that exercise , a balanced diet and healthy living largely hand over towards secretion of some life prolonging hormones . Such healthy individuals are more likely to depict positive behavioral traits such as less moodiness .
