Autonomic nervous system ulawula ukusebenza zonke kwezitho zomzimba. Umsebenzi, ukubaluleka kanye indima autonomic nervous system

Autonomic kwemizwa uhlelo indoda kunomthelela oqonde ngqo ku umsebenzi eziningi izitho zangaphakathi kanye nezinhlelo. Ngenxa wakhe, wenza emishinini yokuphefumula, kwegazi, ukunyakaza kanye neminye imisebenzi yomzimba womuntu. Kuyathakazelisa ukuthi nakuba usithonye eside, autonomic nervous system kakhulu "nezimfihlo", ie. E., Akekho ongaba ngokucacile uzizwe ushintsho wakhe. Kodwa lokhu akusho ukuthi akufanele sikuthathe banake ngenxa indima ANS emzimbeni womuntu.

Isimiso sezinzwa somzimba womuntu: uqhekeko olukhona ngaphakathi

Umsebenzi oyinhloko we-womuntu yesiBethamthetho seNarha - ukudala idivayisi kuzohlanganisa zonke izitho kanye nezinhlelo zomzimba womuntu ndawonye. Ngenxa yalokhu, wayezokwazi ukuthi akhona futhi umsebenzi. Ngesisekelo ukusebenza ohlelweni womuntu sezinzwa uhlobo lwesakhiwo esibizwa ngokuthi namangqamuzana ezinzwa (benza contact nge emsipheni amaza nomunye). Kubalulekile ukwazi ukuthi abantu anatomy NA luyinhlanganisela zindawo ezimbili: isilwane (ukuphathwa kwabathintwayo) kanye ezizimele (vegetative) izinhlelo sezinzwa. Okokuqala wadala ikakhulukazi umzimba womuntu wakwazi ukuxhumana nge imvelo bangaphandle. Ngakho-ke, uhlelo has a yesibili igama layo - isilwane (.. Okungukuthi, isilwane), ngokwenza leyo misebenzi ukuthi esivela kuzo. Inani autonomic nervous system ukuze abantu akuyona njengebalulekile, kodwa ngokuyisisekelo umsebenzi walo abaphila ngayo ihluke ngokuphelele - the ukulawula mikhosi ukuthi banesibopho ukuphefumula, ukugaya kanye nezinye izindima, ikakhulukazi esivela izitshalo (kungakho yesibili igama uhlelo - ezizimele).

Kuyini autonomic nervous system lomuntu?

ANS usebenza ngosizo izinzwa (iqoqo ezinzwa futhi ezihlobene zabo). Nazo ngokufanayo, ukusebenza ngalowo Thumela amasignali ethize kwezitho ahlukahlukene, izindlala futhi izinhlelo zobuchopho nomgogodla. Ngokuthakazelisayo, izinzwa kuyingxenye autonomic nervous system zinomthwalo wemfanelo ukusebenza inhliziyo (ukunciphisa ke), ukusebenza pheshana emathunjini (peristalsis), umsebenzi nezindlala salivary. Empeleni, ngakho-ke, bathi autonomic nervous system uhlela umsebenzi kwezitho futhi izinhlelo ngokungazi, njengoba ekuqaleni le misebenzi babe esivela izitshalo, bese izilwane nabantu. Izinzwa, okuyinto yakha isisekelo VNS, uyakwazi ukudala ezinye ukuminyana, ise asebuchosheni nomgogodla. Banikwa igama "nuclei autonomic." Futhi eduze izitho nomgogodla vegetative umnyango NA uyakwazi ukwakha ganglia. Ngakho, i-nucleus vegetative - liyingxenye eyinhloko kohlelo isilwane futhi ganglia - neuropathy. Empeleni, ANS ihlukaniswe yaba izingxenye ezimbili: the nozwela futhi parasympathetic.

Iyini indima VNS emzimbeni womuntu?

Ngokuvamile abantu ungaphendula umbuzo elula hhayi: "Lo autonomic nervous system ulawula umsebenzi ngalo:? Imisipha, izitho noma izinhlelo"
Eqinisweni, it is, eqinisweni, kuba uhlobo oluthile "impendulo" umzimba womuntu owakheke ngayo ezintweni ezivela ngaphandle ngaphakathi. Kubalulekile ukuqonda ukuthi autonomic nervous system usebenza umzimba wakho wonke yesibili, kodwa umsebenzi salo imperceptible. Ngokwesibonelo, ukulawulwa abajwayelekile isimo sangaphakathi (ukuzungeza, emishinini yokuphefumula, ekuhlukanisweni nabantu bakaJehova, amazinga ama-hormone, njll ...) - kuba indima eyinhloko autonomic nesimiso sezinzwa. Ngaphezu kwalokho, uyakwazi banethonya oqondile ngakolunye izingxenye zomzimba womuntu, isibonelo, imisipha (inhliziyo, lwamathambo), izitho ezihlukahlukene (isibonelo, ukunwetshwa noma ukusikwa umfundi), umdlavuza kohlelo endocrine, nokuningi. Autonomic nervous system ulawula abantu umsebenzi umzimba nge nemiphumela ehlukene ezithweni, okungase evamile emelelwa ezintathu izinhlobo:

- ukulawula umzimba kumaseli zemizimba ahlukahlukene, okuthiwa isilawuli trophic;

- nethonya esisemqoka umsebenzi kwezitho, isibonelo, umsebenzi wokuhlekwa imisipha yenhliziyo - control wesitayela;

- umphumela ezithweni ngenxa sokukhuphula noma ukwehlisa ukugeleza kwegazi - control vasomotor.

Ukwakheka VNS womuntu

Kubalulekile wazi into esemqoka: ANS ihlukaniswe yaba izingxenye ezimbili: the nozwela futhi parasympathetic. Elokugcina kuvame ukuhlotshaniswa izinqubo ezinjalo, ezifana wrestling, ukugijima, t. E. Ukuqinisa nemisebenzi izitho ezihlukahlukene.

Kulokhu kukhona izinqubo ezilandelayo: ukwanda kwenhliziyo imisipha (futhi, ngenxa yalokho, ukwanda blood pressure ngaphezu evamile), ukujuluka yanda, umfundi yanda, abampofu umsebenzi emathunjini peristalsis. I parasympathetic isimiso sezinzwa isebenza ngendlela ehluke, isb. E. ngendlela ehluke ngokuphelele. Yena libhekene izenzo ezinjalo emzimbeni womuntu, lapho lihlale futhi ifunda zonke. Lapho iqala kusebenze indlela ukusebenza kwawo, izinqubo ezilandelayo zenzeka: miosis, ukujuluka encishisiwe, senhliziyo esilimele isisebenza wavuma (ie, it kunciphisa inani ukusikeka ..), emathunjini peristalsis yasebenza, kunciphe umfutho wegazi. VNS akwenzayo kuyinto ukusebenza vysheizuchennyh neminyango yayo. imisebenzi yabo ezihlobene kugcina umzimba womuntu ngo balance. Ngo ngaphezulu alula, yezingxenye idatha ye snc akhona in complex, njalo iphelelisane nomunye. Lolu hlelo lusebenza kuphela ngoba izinhlelo parasympathetic nozwela sezinzwa ziyakwazi lokukhululwa neurotransmitters ezenza futhi kwezitho izinhlelo ngezimpawu emsipheni.

Ukuqapha ukuqinisekiswa autonomic nervous system - kuyini?

Imisebenzi ka-autonomic nervous system kukhona ngaphansi kolawulo okuqhubekayo izikhungo ezinkulu eziningana:

1. emgogodleni. Nonozwela isimiso sezinzwa (SNS) kudala izinto isondelene kuya umgogodla intambo isiqu, futhi izingxenye ngaphandle kulona umelwe division parasympathetic we ANS.
2. Brain. Anakho umthelela kakhulu eliqondile umsebenzi amasistimu parasympathetic nozwela sezinzwa, ukulungisa ibhalansi wonke umzimba.
3. Isiqu ingqondo. Lolu hlobo ubuhlobo obukhona phakathi asebuchosheni nomgogodla. It uyakwazi ukulawula imisebenzi ANS, okungukuthi parasympathetic yayo (blood pressure, emishinini yokuphefumula, kwenhliziyo, njll).
4. Hypothalamus - ingxenye diencephalon. Kuthinta ukujuluka, ukugaya, kwenhliziyo, nokunye. D.
5. Isimiso sezinzwa (eqinisweni, kuba imizwelo yabantu). Kutholwe ngaphansi cortex cerebral. It inomthelela umsebenzi kokubili neminyango VNS.

Ikhumbula ngenhla, kanye nendima ephawulekayo ka autonomic nesimiso sezinzwa, ngoba umsebenzi wayo ilawulwa izingxenye ezifana ezibalulekile zomzimba womuntu.

Imisebenzi eyenziwa yi-ANS

Bona eminyakeni eyizinkulungwane edlule lapho abantu bafunda ukuba basinde kule izimo ezinzima. Imisebenzi ka-autonomic nervous system kuhlobene umsebenzi nezigaba zawo ezimbili eziyinhloko. Ngakho, uhlelo parasympathetic uyakwazi kujwayeleke ukusebenza komzimba womuntu ngemuva kokushaywa yisifo ukucindezeleka (ukusebenza nonozwela ANS uMnyango). Ngakho, ukulinganisela isimo esingokomzwelo. Yiqiniso, le ngxenye SPA futhi unesibopho nezinye izindima ezibalulekile, ezifana Ukuphumula nokulala, ukugaya, nokukhiqizwa. Konke lokhu kwenziwa acetylcholine (ikhemikhali okuhambisa ezinzwa amaza komunye emsipheni fibre kwenye). Umsebenzi division nozwela we ANS sifuna ukuqinisa zonke izinqubo ezibalulekile zomzimba womuntu: kwandisa ukugeleza kwegazi ezithweni eziningi izinhlelo, kwenhliziyo, ukujuluka anda, nokuningi. Lezi zinqubo ukusiza umuntu ukuzwa esimweni esicindezelayo. Ngakho-ke, singaphetha ngokuthi autonomic nervous system ulawula ukusebenza komzimba lwesintu lulonke, noma ngenye indlela ukuthonya ke.

Nonozwela isimiso sezinzwa (SNS)

Le ngxenye snc womuntu exhumene ne ukulwa noma ukusabela komzimba ezintweni zangaphakathi nezangaphandle. Timphawu zimi kanje:

- kubambezela emathunjini (peristalsis), ngokunciphisa ukuhamba kwegazi kuso;

- anda ajulukayo;

- lapho umuntu engancikile emoyeni ngokwanele, VNS ngu ezifanele ezinzwa amaza ubabonisa bronchioles;

- ngenxa vasoconstriction of umfutho wegazi;

- normalizes igazi namazinga kashukela egazini ngenxa ukuncishiswa yayo esibindini.

It is eyaziwa ngokuthi autonomic nervous system ulawula umsebenzi imisipha yohlaka - labo abahileleke ngokuqondile esigabeni yayo nozwela. Ngokwesibonelo, uma umzimba wakho ucindezelwe e lokushisa eliphezulu, VNS nozwela ahlukaniswe ngokushesha usebenza kanje: okuhambisa amasignali afanele ingqondo, futhi-ke, yena, esebenzisa kwemizwa amaza inyuka noma yandisa ajulukayo isikhumba ikhule ezimbotsheni. Ngakho, izinga lokushisa is kakhulu ziyancipha.

I parasympathetic isimiso sezinzwa (PNS)

Le ngxenye ye-SPA ihlose ukwakha isimo womuntu zokuzilibazisa, ukuzola, nokwenziwa kwazo zonke izinqubo ezibalulekile. Umsebenzi wakhe kuyehla ngqo lokhu okulandelayo:

- icacisa ekusebenzeni lonke ipheshana emathunjini, okwandisa ukugeleza kwegazi yabaphathi;

- izenzo ngqo indlala salivary ukuze sikhuthaze ukukhiqizwa ngamathe, kanjalo usheshisa peristalsis;

- kunciphisa ubukhulu umfundi;

- ukusebenzisa control eqinile phezu umsebenzi inhliziyo futhi yonke iminyango yalo;

- kunciphisa ubukhulu bronchioles, lapho izinga le-oxygen egazini kokuvamile.

Kubalulekile ukwazi ukuthi autonomic nervous system ulawula imisipha izitho ezihlukahlukene - inkinga, kuhlanganise wahlanganyela nokuhlukanisa yayo parasympathetic. Ngokwesibonelo, lesizalo Kufinyeta ngesikhathi excitation noma kwangemva kokubeletha ehlangene ukusebenza ohlelweni. A ukwakhiwa owesilisa kungaphansi kuphela ukuba usithonye. Phela, ngosizo emsipheni amaza igazi ukuze zangasese amadoda ngalolo iyaphendula imisipha wenduku.

Indlela ezicindezelayo ukusebenza ngomhla ka-ANS?

Ngithanda ukusho manjalo ukuthi kwaba ukucindezeleka kungabangela ukusebenza engafanele VNS.
Imisebenzi ka-autonomic nervous system labo abazokwazi ikhubazeke ngokuphelele uma kuphakama isimo esinjalo. Ngokwesibonelo, kwakukhona usongo ekuphileni komuntu (lehla itshe elikhulu phezu kwawo, noma phambi kwakhe isigubhukane uvele isilwane sasendle). Othile ngokushesha uyabaleka, kanye nezinye nje kwi freezer endaweni ngaphandle ikhono uthole ugingqe ibhola. It akuxhomekile umuntu, ngakho asabela ngayo ezingeni equlekile ka VNS yayo. Futhi konke lokhu ngenxa eziyimpumelelo ezinzwa elise ubuchopho, le oblongata medulla, limbic system (Ibhekene nemizwa). Phela kuyacaca ukuthi autonomic nervous system ulawula umsebenzi kwezitho eziningi kanye nezinhlelo: wokugaya ukudla, ama-apharathasi zenhliziyo, imifanekiso, umsebenzi emaphashini ngomgudu womchamo. Ngakho-ke, umzimba womuntu izikhungo eziningi angaphendula agcizelele ngokusebenzisa umsebenzi we ANS. Kodwa ungakhathazeki kakhulu, njengoba ingxenye enkulu yokuphila kwakhe, thina abahlangani uthuthumele eqinile, ngakho okuvela izimo ezinjalo umuntu - a rarity.

Ukukhubazeka kule impilo yabantu kubangelwa ukusebenza engafanele ANS

Yiqiniso, kusukela phezulu, kwaba sobala ukuthi autonomic nervous system ulawula umsebenzi kwezitho eziningi izinhlelo emzimbeni womuntu. Ngakho-ke, iyiphi ukungakhuli ukusebenza umsebenzi walo zingaphazamisa kakhulu ukuhamba komsebenzi. By the way, izimbangela zezinkumbulo lezi zinkinga kungase noma ngofuzo noma ukugula aluthola ngesikhathi ukuphila. Ngokuvamile ukusebenza VNS umuntu "esingabonakali" imvelo, kodwa izinkinga lo msebenzi kakade ebonakalayo ngesisekelo zimpawu ezilandelayo:

- System Ngethukile: ukungakwazi komzimba ngaphandle kosizo ukunciphisa izinga lokushisa lomzimba;

- Git: ukuhlanza, ukuqunjelwa noma isifo sohudo, ukungakwazi ukugwinya ukudla, incontinence urinary, nokuningi;

- izinkinga zesikhumba (ukulunywa, ububomvu, uyaxebuka), izinzipho ziyaqothuka futhi izinwele, anda noma kwehle ukujuluka;

- Vision: izithombe esilufifi, ukungabi izinyembezi, ubunzima ngokugxila;

- zokuphefumula uhlelo: ukuphendula okungafanele ukuba umoya-mpilo okuqukethwe ongaphakeme noma ukunyuka komfutho;

- inhliziyo futhi semithambo uhlelo: nakwisyncope, palpitations, iphika, isiyezi, enkeneneza ezindlebeni;

- urinary system: izinkinga ubuciko (incontinence, imvamisa urinary);

- uhlelo zokuzala: ukungakwazi sifinyelele eqophelweni lokwaneliseka ngokobulili, ukumiswa kwesikhathi.

Abantu abaphethwe rastrojstvah ANS (peripheral autonomic), ngokuvamile asikwazi ukulawula ukuthuthukiswa yayo. Ngokuvamile kukhona ukungasebenzi okuqhubekayo autonomic evela sikashukela. Futhi kulokhu kuyoba okwanele ukuba ngokuqinile ukulawula amazinga kashukela egazini. Uma isizathu ihlukile, ungavele ukulawula lezo zimpawu, okuyinto ngezinga elingakanani kuholele peripheral autonomic:

- emathunjini uhlelo: kulondolozwa imithi yokwelapha ukuqunjelwa kanye nesifo sohudo, ukuzivoxavoxa, ukuba yenyuse; nokugcina ukudla ukudla okuthile;

- isikhumba: kanye lomnotho amafutha okhilimu, kusiza ekudambiseni ukucasuka; antihistamine ukunciphisa ukulunywa;

- uhlelo senhliziyo: Khulisa baphuza uketshezi; ukugqoka izingubo ezikhethekile; imithi elawula umfutho wegazi.

It lingahunyushwa baphetha ukuthi autonomic nervous system ulawula umsebenzi ukusebenza cishe wonke umzimba womuntu. Ngakho-ke, izinkinga abazalwane ababehlangabezana nazo umsebenzi, kudingeka ukuthi ibonakale futhi wafunda ngumuntu ochwepheshe abaqeqeshiwe wezokwelapha. Ngemva VNS ukuze ezinkulukazi womuntu - kwaba sibonga wakhe, wafunda "ukusinda" ezimweni ezicindezelayo.
