Inkqubo onovelwano luvo kunye nemisebenzi yayo

Le nkqubo yawo luvo, ekwabizwa ngokuba yawo, linamacandelo eziliqela okanye iindawo. One of them - novelwano luvo. Icandelo kumacandelo ezisekelwe kwiimpawu ezisebenzayo morphological. Enye zenyathi yinkqubo parasympathetic luvo.

Kubomi kukho eziphilayo luvo yenza uluhlu olubanzi lweempawu eyenza kube ngokubaluleka eliphezulu kakhulu. Ngokwawo, le nkqubo inzima kwaye amasebe eziliqela kunye zenyathi, ngamnye oluthathela ngeminye imisebenzi. Uninzi umdla kukuba kokokuqala loo nto njengoko inkqubo onovelwano nervous wabonakala ngowe-1732. Ekuqaleni, lo gama lisetyenziswa ukuchaza yonke inkqubo yawo luvo. Kodwa njengokuba ulwazi ezingasetyenziswanga izazinzulu, babona ukuba apha kukho umaleko olubanzi kakhulu, ngoko lo mba baqala ukubiza zenyathi omnye kuphela.

Xa siqwalasela iinqobo ezithile, kufumaniseka ukuba inkqubo onovelwano nervous yenza imisebenzi ncam umdla umzimba - elijongene nayo ukuba ukusetyenziswa kwezibonelelo, kwakunye badibane imikhosi ngexesha likaxakeka. Ukuba kukho imfuneko yoko, inkqubo onovelwano kwandisa inkcitho lwamandla, ngoko umzimba aqhubeke ukusebenza ngokwesiqhelo kwaye lenze imisebenzi yalo. Xa sithetha ngayo amathuba efihlakeleyo kunye nezixhobo, sithetha kanye oko. Kwi indlela nkqubo uya kuzisingatha kakuhle oko, kuya kuxhomekeka kwimeko yomzimba.

Noko ke, konke oku ni ntshikilelo womelele umzimba, elide kangaka kweli imo, oko unako ukusebenza. Apha uza kwinkqubo parasympathetic, eba umsebenzi kwezibonelelo kunye nokwanda kwabo nokubuyiselwa, ukuze kamva mntu unako ukwenza imisebenzi efanayo, kodwa iimpawu yayo alibhekiseli. I novelwano kunye nenkqubo parasympathetic luvo ukuvumela eqhelekileyo yokusebenza komzimba womntu kwiimeko ezahlukeneyo. Zisebenza zinenjongo narhoqo ezihlobeneyo.

device yokwakheka

Inkqubo onovelwano luvo unzima kakhulu nesakhiwo branched. Inxalenye engundoqo ise umnqonqo kwaye sikwi idibanisa ezahlukeneyo ganglia kunye nesiphelo emzimbeni. Eneneni kwalapho onovelwano oxhulumene kwi izicwili ezininzi innervated kwi plexus.

inkqubo ukhandwa kwimiphetho ezahlukeneyo luvo sensory afferent kwi oqhubekekisa ethile inkunkuma. Bona zisuswe umnqonqo waza wavuna ikakhulu kwiindawo prespinal kunye paravertebral.

Umsebenzi yenkqubo onovelwano

Njengoko kuchaziwe ngaphambili, inkqubo onovelwano iyasebenza ngokupheleleyo kwiimeko uxinezeleko. Kwezinye imithombo ibizwa ngokuba luvo novelwano lovukelo, kuba kufuneka anike impendulo ethile umzimba ukuba le meko, wabumba ngaphandle.

Kweli thuba esinobubovu adrenal iqala ukuvelisa iadrenaline, nto leyo ke into ephambili evumela abantu ukuba ngcono basabela njani kwiimeko ezibangela ngokukhawuleza. Noko ke, kukho imeko efanayo ezingenzeka ngethuba umthambo, xa ngenxa kokukhutshwa adrenaline umntu uqala ukumelana nayo ngcono. adrenaline secretion kuphucula yintshukumo yenkqubo onovelwano, leyo uqalisa 'ukunika' izibonelelo ukutyiwa amandla kakhulu kuba kuphela iadrenaline uyayivuselela amasebe awohlukeneyo kunye izivamvo, kodwa okunene ngumnikazi resource.

Igalelo umzimba phezulu ngokwaneleyo, kuba ngelo xesha umntu ufumana ukudinwa, ukutyhafa, njalo njalo, kuxhomekeke ukuchitha ixesha elide kangakanani na isiphumo iadrenaline kunye ixesha elide kangakanani inkqubo onovelwano izibonelelo zokuxhasa umsebenzi umzimba kwinqanaba elifanayo.
