Izimpendulo Ezenzakalelayo Zomzimba Wakho nokuthi Kungani Ukuhlolwa Kwadokotela Kuzo
I-reflex iyinhlangano yokuzibandakanya okungazibandakanyi ekugqugquzelweni. Kuyindlela elula (kepha ebucayi) umzimba wakho udlulisela ulwazi olungakaze lufike ekuqapheliseni okuqaphelayo . Iningi lethu lithatha okuningi lokho umzimba owenzela kithina, futhi lokho kuyinto enhle. Kungaba nzima kakhulu ukuhlela nokusebenza ngenkuthalo yonke inhlangano esincane esenzayo.
Njengoba ufunda lokhu, ukulungiswa okucashile kwenziwa njalo phakathi kwemisipha yomgogodla wakho ne-torso ukugcina ulinganise. Amehlo akho enza ukulungiswa okuncane kwansuku zonke kwekhanda lakho. Abafundi bakho bahlaziye ngokufanele ukulungisa izinga lokukhanya nokugxila kulokho okuphambi kwakho. Uma ugwinya, umphimbo wakho uvala ngokuzenzakalelayo umoya wakho ukuze uvimbele umsila ekuhlaleni ithubhu engalungile. Ukuphefumula ngalunye ozithatha ngokuzenzakalelayo ukufundela ukunikeza ibhalansi elungile le-oksijeni ne-carbon dioxide egazini lakho, kanye nokuthatha ukuphefumula okujulile manje nokugcina amaphaphu avulekile.
Lezi zibonelo ezimbalwa zezimpendulo ezizenzakalelayo ezigcina sisasebenza nsuku zonke. Iningi lemisebenzi ebaluleke kakhulu empilweni ingaphandle kokulawula kwethu okuqaphelayo. Esikhundleni salokho, le misebenzi ilawulwa yizindinganiso.
Yeka indlela ukucabangela okusebenza ngayo
I-reflex ejwayelekile kunazo zonke yi-refel patellar, lapho amadolo afika khona lapho udokotela ewuthatha ngesando.
Nakuba lokhu kubhekwa njengengqondo elula, amakhasi amaningi angase agcwaliswe ukuhlola imininingwane yayo yobuchwepheshe. Ngamafuphi, lokho okubonayo ngumzamo womzimba ozenzekelayo wokulungisa ukungalingani okungase kubangele ukuwa. I-muscle isolwe yinyundo yokushaya ithoni, futhi isignali kagesi ithunyelwa emgodini womgogodla, othumela isibonakaliso ukuze ucindezele umsizi ukuwubuyisela ubude bawo.
Umphumela ukunyakaza okufushane, futhi idolo liphuma.
Ngesikhathi esifanayo, isignali kagesi ithunyelwa emisipha ephikisanayo ukuze isitshele ukuthi lezi zinhlanzi ziphumule ukuze zingaphazamisi ukugxilisa umlenze. Ayikho isignali kagesi edingeke ukuba ifinyelele ebuchosheni ukuze kuvele lokhu.
Kungani Odokotela Bezama Ukuziphendulela?
Izazi ze-neurologists zisebenzisa izimpikiswano ezahlukene ukubona ukuthi izingxenye ezahlukene zesimiso sezinzwa zisebenza kanjani. Isibonelo, ukuze i-reflex ye-knee-jerk isebenze, izinzwa ezivela nasesiswini kumele zihambisane, futhi intambo yomgogodla idinga ukusebenza kulelo zinga. Ngokufanayo, i-brainstem reflex, njengabafundi abavimbela ukukhanya , ingasiza isazi sezinzwa ukuthi i-brainstem isebenza kahle.
Ngaphezu kwalokho, ukucabangela kuhlolwe ezinye izinto eziningi emzimbeni. Isibonelo, ubuchopho buvame ukuthumela imfucuza phansi komgogodla ogcina izixuku ezinjengokuthi idolo lithele kancane. Ngemuva kokushaywa komzimba noma ukulimala ebuchosheni, ukwehlisa ukukhungatheka kwe-reflex kuyalahleka kancane, futhi lokhu kuholela ekuziphenduleleni kokungasebenzi kahle. Esinye sezizathu zezinzwa zezinzwa hlola ukucabangela ukubona ukuthi kukhona ukungalingani phakathi kwamaceleni kwesobunxele nangakwesokudla, okungaba yinkinga yokulimaza ebuchosheni noma emthonjeni womgogodla.
Ngezinye izikhathi ukucabanga kungabheka okuningi njengokuziphatha okuqaphelayo. Isibonelo, "i-reflex triple", i-knee, i-hip, nezinyawo ziguquguquka ngendlela yokuthi umlenze uhoxise lapho kusetshenziselwa ukuvuselela okubuhlungu. Lokhu kungenzeka ngisho noma isibonakaliso kagesi singalokothi sifinyelele ebuchosheni-singasungulwa ngokuphelele ngentambo yomgogodla. Kubalulekile ukuhlukanisa phakathi kokunyakaza kwenhliziyo nokuzimisela ezimweni ze-coma noma ukuguqulwa kokuqonda.
Ukungazi konke okusikhumbuzayo kusisindisa izinkinga eziningi ekuphileni kwansuku zonke. Kodwa-ke, ukwazi ngezimo ezibucayi nendlela yokuzihlola kungaphazamisa ukukhanya kwesistimu yezinzwa futhi lapho inkinga ingase ilele ohlelweni lwesifo sezinzwa.
