Heredity And Hormones

IntroductionHuman behavior varies from individual to individual . The tendencies to commit crimes , be lots aggressive or to be more intelligent ar all indicators of human behavior . Biologically speaking , this behavioural out dos argon a direct consequent of endocrines and genes . The relation surrounded by these two aspects shall be examined belowA line of descent of the utilisation of genetic endowment and innate secretionsWhile ductless glands guide construct defined roles by dint ofout one s life conviction , genes , which chance on genetic endowment , atomic number 18 responsive to the milieu and their role intelligibly diverges with respect to the purlieu . It should be noted that heredity is not some sort of master puppet holding the draw and controlling the environment . As a matter of numberrence , genes switch over or evolve based on the environment pastce explaining the footing 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 similar way it does years to come Conversely , hormones atomic number 18 rattling specific in reputation , their presence or absence may change exactly their role remains perpetually the same . For instance , the hormone insulin is always responsible for canon 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 cha nges forms the lynchpin of the `principle o! f the feedback tool . When the frame has been overcomeed to an unusual situation that stimulates fearfulness within the field of force , then the top dog exit 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 dinero producing this hormone and waits for the next scenario . The process of waiting for want o f 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 supply contraceptives in to suppress the actions of reproductive hormones such as progesterone . This subsequently affects the overall behavior of the individual because they are twain pregnant or not . Similarly , it has been shown that exercise , a balanced diet and healthy living largely reelect 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 websi te: OrderCusto! mPaper.com
