Conduction ndi reflex ntchito ya chingwe msana

Msana ubongo wa munthu ndi njira zovuta kuti wapangidwa ndi osiyana "ziwalo" ambiri. Ndipo aliyense wa iwo ndi zofunika kwa moyo wathu wonse. Chifukwa chakuti tili ndi msana, ife ikuyenda. Reflex ntchito ya chingwe msana ndi zazikulu, zimene iye amachita. Kuwonjezera izo, pali kondakitala. Ndi bwino kuganizira zinthu izi zambiri ndi kupeza chimene aliyense wa iwo ndi udindo.

Mapangidwe ndi chingwe msana mu wosabadwa kumachitika m'mimba, ndipo mu kamphindi, pamene iye anali akadali sadziwa pakati. Pofika kumapeto kwa mwezi woyamba, maziko woyamba wa mzati msana. Komabe, malizitsani mapangidwe ake atabadwa azitenga ena nthawi zambiri. M'madera ena a ubongo, ndi potsiriza anapanga, pamene mwana akutembenukira zaka 2.

Kodi chingwe msana

Izo zikuwoneka ngati chingwe msana, si aliyense amadziwa. Komanso, si anthu onse ndi lingaliro la zimene cholinga chake mu moyo aliyense. Mogwirizana ndi izi kudzaza kusiyana izi nzeru. Komanso, anthu ambiri molakwa kuti ubongo ndi msana - ndi gawo osiyana.

Kuti tipeze chifukwa chake muyenera ntchito reflex wa chingwe msana, yesetsani kuona chimene chimaoneka. Ndithudi kuwona kumene izo zikuyamba ndi kumene mapeto chingwe msana, sikutheka. Umayamba kwa linkawonongeka loyamba basi pansipa chigaza ndi pang'onopang'ono kulumikiza ndi ubongo mderali. Kudulidwa mu ubongo ndi msana ndi atione zoona, chingwe msana bwino mu mutu. Choncho, tinganene kuti mbali ziwirizi ndi gulu limodzi.

Malo a chingwe msana ndi zikopa zake

ubongo amateteza chigaza ndi msana zobisika msana ndi wazunguliridwa ndi nembanemba atatu. Choyamba mwa zinthuzi ndi ambiri wosakhwima, woonda ndi zofewa. Iwo anabisidwa ziwiya magazi kuti apulumutse zakudya ubongo. M'mawu ena, chingwe msana ndi mtundu wa "Mtumiki" wa yobereka mphamvu.

Kupitiriza kulankhula za mmene ntchito reflex wa chingwe msana, sangathe kupitirirapo mbali yachiwiri ya dongosolo kusanthula arachnoid lapansi. Apa pali malo apadera, ndilo lotchedwa subarachnoid. Kwa kutalika kwa msana, ndi wodzazidwa ndi madzimadzi cerebrospinal (CSF). Anali ndi kutenga njira ya puncturing pa kusanthula kudziwa ukupeza wa chingwe msana.

chipolopolo Last ili kunja ndipo ali pamwamba zovuta kuti imathandiza kupereka ntchito yake zoteteza ndi kuvulala osiyanasiyana akunja.

Makhalidwe a chingwe msana

Mu anthu wamkulu msana m'litali mpaka masentimita 45 ndi makulidwe a 1.5 cm. Imatha kulemera conservatively miyezo si magilamu 35. Ubongo lonse lagawidwa m'magawo angapo, amene achoka ku mizu yosiyanasiyana:

• khosi;
• chifuwa;
• lumbar;
• Kampeni;
• coccyx.

Choncho mmene reflex ntchito ya msana, khomo lachiberekero ndi lumbar-sacral dera ndi mbali yofunika kwambiri pa msana. Pa nkhani imeneyi, iwo inkatetezeka - chikhalidwe watenga kusamalira, kuwapanga chachikulu ndiponso lolemererapo. Ilo liri mu malo awa ndi misempha zofunika, yomwe INGATHE kuyambitsa mavuto aakulu la kugonjetsedwa. Msana khomo lachiberekero ndi kudzikundikira mizu, amene kayendedwe ka manja. Mizu ya kugawikana m'munsi ndi udindo kayendedwe ka miyendo m'munsi.

The anthu msana akulamulira ntchito ziwalo zonse za mkati. Aliyense wa iwo amagwirizana ndi dipatimenti iliyonse. Komanso, lonse msana ngalande lagawidwa zigawo, ndipo aliyense wa m'madipatimenti awa ali nambala yake. Mu khosi lawo 8, mu bere - 12 mu lumbar ndi sacral 5, ndi coccygeal iwo ali limodzi kapena awiri.

Kodi mkati?

Kupeza momwe kuonetsetsa imaonetsa ndi ntchito conductive wa chingwe msana, mukazonde mkati. Ubongo lonse ndi osiyana heterogeneity mu kapangidwe ndi mtundu. Pakati ndi imvi kanthu, umene wazunguliridwa ndi woyera. Aliyense ali ndi udindo ntchito zina, zomwe zina ayankhidwa.

nkhani imvi

Gray kanthu kapena substantia grisea umaimiridwa ndi zipilala angapo amene chikugwirizana ndi mzake ndi mbale awiri (kutsogolo ndi pansi), wotchedwa spikes. Pa gawo la wina wa zipilala zimenezi Tingaone kuti nkhani imvi mu mawonekedwe akufanana gulugufe ndi mapiko kufala kapena Latin kalata H.

Komanso, mukhoza zindikirani kuti thunthu kuwonjezera zolosera kuti sakanavomereza otchedwa nyanga. Iwo akhoza kukhala mwina kutsogolo, pa khoma kutsogolo ndi kumbuyo akuthamanga khoma kumbuyo. Ndipo woyamba ndi wachiwiri awiri, ndipo ali ndi lopapatiza lonse mawonekedwe. Koma kuwonjezera kutsogolo ndi kumbuyo, palinso nyanga ziwiri, amene akachita malo mantha dongosolo autonomic.

ndi ntchito reflex wa chingwe msana chiyani? mfundo ndi yakuti mu nyanga zapambuyo ndi wapadera manyuroni galimoto, njira zomwe ndi mizu mitsempha.

Middle imvi nkhani apatsira njira chapakati, chomwenso ndi wodzazidwa ndi mowa. The kumtunda kwa njira chikugwirizana kuti ndi ventricles ubongo. Pankhaniyi, zigawo zonse: ventricles, ngalande chapakati ndi subarachnoid danga ndi kukhala wochitachita mu makope madzimadzi cerebrospinal.

nkhani woyera

White mankhwala - substantia alba, malaya imvi, anapanga ya ulusi mitsempha, amene anabwera ku mitundu itatu:

• kutsogolo;
• kumbuyo;
• mbali.

Pankhaniyi mizu onse ndi madera osiyana, ndi ena a iwo mwachindunji zokhudzana ndi ubongo ndi dongosolo chapakati mantha (hereinafter chabe CNS). Ndipo ngati ntchito reflex wa chingwe msana ndi popereka chizindikiro cha manyuroni galimoto ya nkhani imvi, vuto la okhudza mitsempha kanthu woyera - ndi yobereka mwamsanga nyemba kwa minofu ndi mafupa wa medulla oblongata. Choncho, anazindikira kulanda magulu onse pamodzi chingwe msana.

Pano pali njira zimene kusamutsa zayamba onse nkhani tilinazo ndi ululu. Atangotsala pang'ono inu kulowa kotekisi oziziritsa, mudziwe woyamba umalandira ubongo wapakatikati, ndi pamenepo pokha iri yofulumira kuti ikupita.

The ntchito ubongo wathu

Kwa ntchito mwamsanga ndi lolondola la thupi udindo akwera natsikira njira. mitsinje Recent amayambira ntchito krasnoyadernyh ndi njira lateral. Ndi kudzera njira ameneŵa reflex conduction ndi msana ntchito. Chifukwa krasnoyaderno-msana njira opangidwa galimoto zikhumbo musanaganizire. Ngakhale kuti zilakolako umasinthasintha udindo lateral njira cortico-msana.

mizu onse aziwapatsa mitsempha munthu ndi mitsempha, chifukwa cha kupanga mtolo neurovascular. Aliyense mtengowo uli ndi ntchito gawo yake ndi mu muli osalumikizidwa, ndi Kusanthuka deta ukubwera ndi kupatsira zilakolako kutero.

Kugonjetsedwa kwa milimo ya kumabweretsa kusintha lalikulu pathological ndi zina sizingasinthe mu thupi la munthu. Ndipo kotero akatswiri akhoza kudziwa mtengo chawonongeka, ndipo isanafalikire ululu, maphunziro ambiri a adzafuna.

ntchito reflex

Thupi lathu bwino anakonza, ndipo aliyense nzothandiza kunja, thupi lathu amachitira mosiyana. Bukuli lili ndi bongo wa limagwirira chitetezo. Ife sneezes, akutsokomola, kupeza amayaka, akuyamba ku phokoso lakuthwa kapena njira zawo anatani gusts mphepo. Izi ndi zitsanzo zonse za ntchito reflex wa chingwe msana ndi zochita zina zotere wochitika kunja kwa kuzilamulira.

Kotero kuti ife tikhoza kuyankha nzothandiza aliyense, kuphatikizapo zinthu yovuta padziko lonse wa khungu lathu anayikidwa nociceptors. Mwachitsanzo chooneka: kukhudza ketulo otentha kapena pamwamba aliyense, ife pasanapite nthawi anabwerera ndi dzanja lake. Mlingo anachita ndi mofulumira kuti n'zosatheka kumvetsa munthawi. Pakuti reflex anapangidwa wa mphete chachiwiri, zomwe zimabweretsa minofu ndi kuchepa.

Mungapereke mulandu wina pafupipafupi. Atayima amangotchula ndimweko gawo la utsi kapena fumbi kuyimitsidwa kukoka mphuno, sneezing kapena kutsokomola kumayamba. Choncho, zinadziwika kuti nthawi yochepa ngati mudziwe chinapezeka, kukonzedwa ndi wathu "zokometsera" kuti ataphunzitsidwa kumasula thupi pamaso pa matupi yachilendo.

conduction ntchito

Choncho, chimene chimaoneka mu ntchito reflex wa chingwe msana, tsopano bwino, inu mukhoza kupita kwa ena, komanso vuto chidwi - mawaya. Yankholo mu kufala kwa chizindikiro mu akukwera njira kuti ubongo waukulu. Mmenemo zoopseza, ndi patsogolo pa njira kunsi walangizidwa ulamuliro uliwonse.

Conduction ntchito amatilola kuti kanthu watanthauzo:

• kutenga kapena kutaya;
• ayimirire kapena kukhala;
• kupita pang'onopang'ono kapena kuthamanga;
• kujambula;
• kudula.

Zonse zimene timachita pa moyo wa tsiku ndi tsiku zinthu izi: kunyumba kapena kuntchito ndi zambiri monga osaganizira.

Zonsezi kugwirizana ubongo, msana, lonse chapakati mantha dongosolo, ziwalo ndi nthambi za thupi la munthu yapadera mu chikhalidwe chake. Ngakhale Makina zotsogola sangathe kudzitama chiwerengero cha magulu awo, okhoza kuchita bioorganisms iliyonse.
