Izinga reaction neendlela zayo yokwanda

Izinga abasabela yenye iimpawu eziphambili nayiphi na esiphilayo. Kubaluleke kakhulu ukuphendula etyabulayo ngaphandle nje ngephanyazo, njengoko abathile kubo bafunyanwe nje yingozi, yaye ezibulalayo.

Ukususela ekuqaleni ifuthe ngqo isivuseleli de indlela isoloko ixesha kuya kuthatha ixesha elithile, ngexesha apho inyathelo Uvula kwiimpendulo izihlunu, athi abenoxanduva ngesantya umlinganiselo reaction kakade. eli xesha akukholibaziso ngokuba "ixesha lokuphendula kokulinganisa." Ixhomekeka izinga ukutya kwaye ebalasele inkalo ngamnye kumzimba ethile. Eli xesha kokulinganisa akakwazi ukuqeqesha njenge ayinakwenzeka physiologically ukukhawulezisa ukosuleleka neemvakalelo-luvo.

Isantya avareji impendulo yoluntu nezibonwayo umqondiso kuphela malunga kwikota yesibini. Eli nani lixhomekeke luvo. Umzekelo intsabelo yabantu nokurhawuzela ngokwanelisayo kakhulu, nto leyo inokuba ezisongela ubomi. Xa Betha esandleni ukusuka isitovu ebuchotsheni eshushu athathe inxaxheba. Uphawu ukusuka receptor ifayibha luvo engena umnqonqo kwaye ngoko nangoko esihlunwini, ngoxa edlula phantsi iiseli zemithambo-luvo ezintathu: iiseli zemithambo-luvo, luvo yovakalelo, kunye luvo motor. Izinga yendlela ngohlobo a ngokwentshukumisa-luvo kulo mzekelo, inani walinganisa kwamashumi eziliqela ngomzuzwana.

Okokuqala umntu osusa isandla sakhe, waza kamva wabonakala intlungu. Oku kungenxa yokuba i ecothayo umqondiso ngesantya esentlango, ephuma receptors intlungu ingqondo kunye luvo sohlobo eyahlukileyo kunokuba zidweliswe ngasentla.

Ukukhangela indlela yabantu ilitye eziphaphazelayo kuyo, yaye imi ngolu hlobo lulandelayo: ngoncedo iliso ithumela umqondiso malunga intshukumo, hayi nje kuphela kweli ubuchopho, apho kufuneka ukuba lumakishwe, kodwa endleleni yokubenza ezithile luvo kwizihlunu, nto leyo eza kunceda ukuqinisekisa impendulo ekhawulezileyo kunye nokhathalelo icala.

Ngenxa impumelelo izazinzulu zonyango namhlanje akwazi ukungqina ukuba ngesantya umntu of yokusabela kwandisa. Kuye kwenziwe abadlali bebhola, abadlali ihoki kunye nabadlali intenetya baqeqesha ngexesha elifanayo uyondelelwano lwee- ingqalelo zabo kwiziza eziliqela. Iziphumo zabonisa ukuba emva ukuqeqesha ubuchule ngaxeshanye "nokufunxwa" kwenkcazelo kakhulu ukusetyenziswa kwayo imveliso kunyuke nge-53%.

Izinga abasabela yenye iimpawu eziphambili apho amisele ngenxa lokulwa ngomsesane. Ngapha koko, ukususela nokuchaneka kunye nesantya mpendulo amanyathelo utshaba rhoqo kuxhomekeke kuphela kwi uloyiso emfazweni, kodwa ubomi nempilo ngokwabo mlilo.

Ukuphucula ukusabela kwizinto ezandulela inyathelo linobungozi kufezekiswa ngokuthi, umzekelo, indlela akuthethi ukuba avuthele aze ukuba ziqalise ukwenza amalungiselelo oko. Ngapha koko, utshaba phambi exabela, qiniseka ukuba ukujonga ithagethi, izabalazela izihlunu, utshintsho ukuma, njl Ufuna kuphela ukusebenza ezinye uhlobo reflex ubeke impendulo isiqaqa kwizivuseleli entsha.
