Indlela I-Nervous System Ebona Ngayo Futhi ihumusha Ubuhlungu
Ubuchopho bakho buyazi kanjani uma uzwa ubuhlungu? Uyazi kanjani umehluko phakathi kokuthinta okunciphisa kwe-feather ne-prick needle? Futhi, lolo lwazi lufika kanjani emzimbeni wakho ngesikhathi sokuphendula? Ubuhlungu obukhulu buba kanjani ubuhlungu obungapheli ? Lezi akuzona izimpendulo ezilula, kodwa ngokuchaza okuncane mayelana nendlela uhlelo lwesimiso olusebenza ngayo, kufanele ukwazi ukuqonda izinto eziyisisekelo.
Uhlelo Lwezinzwa
Isistimu yakho yezinzwa yenziwe izingxenye ezimbili eziyinhloko: ubuchopho nentambo yomgogodla , ehlanganisa ukwakha isimiso sezinzwa zomphakathi; kanye ne-sensory and motor nerves, ezakha isimiso sezinzwa zomzimba. Amagama enza kube lula ukumbona: ubuchopho nomgogodla yiwona ama-hubs, kuyilapho izinzwa nezinzwa zomzimba zisuka ukuze zinikeze ukufinyelela kuzo zonke izindawo zomzimba.
Ngokumane nje, izinzwa ezizwayo zithumela izimpendulo mayelana nalokho okwenzeka emvelweni wethu ebuchosheni nge-spinal cord. Ubuchopho buyithumela ulwazi emuva kwamagundane, okusize senze izenzo. Kunjengokuthi kunenkinga kakhulu futhi ngaphandle kwebhokisi yento yonke.
Ubuhlungu Buqala Ngezinzwa
Ake sithi uhamba edwaleni. I-nerve ye-sensory ohlelweni lwesiphazamisi sezindiza yayazi ukuthi ihlukile yini kunento efana nethoyizi elithambile? Izinhlobonhlobo zezinzwa ezihlukahlukene zithinta izinto ezahlukene, futhi zikhiqize izimpendulo zamakhemikhali ezahlukene ezikhomba ukuthi ukuzwela kuhunyushwa kanjani.
Ezinye izinzwa zithumela izimpawu ezihlobene nokuthinta ukukhanya, kanti abanye baphenduka ekucindezelekeni okujulile.
Izamukeli ezikhethekile ezibuhlungu ezibizwa ngokuthi i- nociceptors zisebenze noma nini lapho kulimale, noma ngisho nokulimala okungase kube khona, njengokuphuka isikhumba noma kubangele ukufakwa okukhulu kwe-indentation. Ngisho noma idwala lingaphuli isikhumba sakho, izicubu ezinyaweni zakho zicindezelekile ngokwanele ukuba zenze umlilo we-nociceptors uvulwe.
Manje, umfutho ufinyelela ku-nerve kumgogodla, futhi ekugcineni yonke indlela eya ebuchosheni bakho. Lokhu kwenzeka ngaphakathi kwezingxenyana zesibili.
I-Cinal Your Cord: Umuntu Ophakathi
Intambo yakho yomgogodla iyinkimbinkimbi yezimbungulu zezinzwa, ithumela zonke izinhlobo zamasignali futhi kusukela ebuchosheni nganoma isiphi isikhathi. Kuyinto enjengeyomgwaqo ongasenhla wezimvo zokuzwa nezinzwa. Kodwa intambo yomgogodla yakho ingaphezu kokusebenza njengesikhungo somyalezo: singenza izinqumo ezithile eziyisisekelo ngokwakho. Lezi "zincumo" zibizwa ngokuthi i- reflexes .
Indawo yomgogodla obizwa ngokuthi uphondo lwe-dorsal lusebenza njenge-hub yolwazi, ngesikhathi esifanayo iqondisa izimpikiswano ebuchosheni futhi ibuyele phansi umgogodla endaweni yokulimala. Ubuchopho akudingeki ukuthi utshele unyawo lwakho ukuthi luhambe edwaleni ngoba uphondo olubiziwe seluthumele lo mlayezo. Uma ubuchopho bakho buyi-CEO yomzimba, khona-ke intambo yomgogodla ukuphathwa okuphakathi.
Indlela Ubuchopho Bakho Bubuhlungu Ngayo
Nakuba i-reflex ye-spinal igxuma emcimbini wokugcoba, ubuchopho buyaqhubeka nobuchopho. Lokhu kungenxa yokuthi ubuhlungu buhilela okungaphezu kokugqugquzela nokuphendula okulula. Ukuthatha unyawo lwakho nje edwaleni akuxazulula zonke izinkinga zakho. Kungakhathaliseki ukuthi umonakalo omncane kangakanani, izicubu ezinyaweni zakho zisadingeka ziphulukiswe.
Ngaphezu kwalokho, ubuchopho bakho kudingeka buqonde ukuthi kwenzekani. Ubuhlungu buyatholakaliswa emtatsheni wakho womtapo, futhi imizwelo ihlotshaniswa nokuwela kulolo dwala.
Uma isibonakaliso sobuhlungu sifinyelela ebuchosheni siya kwi-thalamus, esiyiqondisa ezindaweni ezimbalwa ezihlukene zokuhumusha. Izindawo ezimbalwa ku-cortex ziveza ukuthi ubuhlungu buvela kuphi futhi buqhathanise nezinye izinhlobo zobuhlungu obujwayele. Ingabe ubukhali? Ingabe ubuhlungu ngaphezu kokuya phezulu? Wake wake wawela edwaleni ngaphambili, futhi uma kunjalo kungcono noma kubi nakakhulu?
Izimpawu nazo zithunyelwa kusukela ku-thalamus kuya ohlelweni lwe-limbic , okuyisisekelo somqondo sobuchopho.
Ngaso sonke isikhathi uyazibuza ukuthi kungani abanye ubuhlungu benza ukhale? Isistimu ye-limbic inquma. Imizwa ihlotshaniswa nazo zonke izinzwa ozithola, futhi umuzwa ngamunye udala impendulo. Izinga lakho lenhliziyo linganda, futhi ungase uphuthumele. Konke ngenxa yecwala eliphansi.
Lapho ithola khona kunzima
Nakuba kungase kubonakale kulula, inqubo yokuthola ubuhlungu iyancipha yiqiniso lokuthi akuyona indlela eyodwa. Akuyona indlela yokusebenza emibili. Ubuhlungu bungaphezu nje kwesizathu nomphumela: kuthinteka yilokho okunye okuqhubekayo ohlelweni lwezinzwa. Ukuzizwa kwakho, okuhlangenwe nakho okudlule, nokulindeleke kwakho konke kungashintsha indlela ubuhlungu obuhunyushwa ngaso sonke isikhathi. Kwenzeka kanjani lokho ukudideka?
Uma uhamba phezu kwaleli dwala ngemva kokulwa nomkakho, impendulo yakho ingase ihluke kakhulu kunokuba ngabe ngabe usanda kunqoba ilotho. Imizwa yakho mayelana nalolu phiko ingase ihlambuluke uma isikhathi sokugcina usuwela edwaleni, unyawo lwakho lutheleleke. Uma wawela edwaleni ngaphambili futhi akukho lutho olubi olwenzekile kuwe, ungase uphinde uthole ngokushesha. Ungabona ukuthi imizwelo ehlukene kanye nemlando inganquma kanjani impendulo yakho ebuhlungu. Eqinisweni, kunesixhumanisi esinamandla phakathi kokucindezeleka nobuhlungu obungapheliyo .
Lapho Ubuhlungu Obunzima Buba Isiguli
Kulesi simo, ngemuva kokuba unyawo lwakho luphulukiswe, ukuzwa kwemizwa kuzoyeka. Lokhu kungenxa yokuthi ama-nociceptors awasatholi noma yikuphi ukulimala kwezicubu noma ukulimala okungenzeka. Lokhu kuthiwa ubuhlungu obukhulu. Ubuhlungu obukhulu abuphiki emuva kokulimala kokuqala sekuphulukisiwe.
Ngezinye izikhathi, noma kunjalo, ama-receptor ubuhlungu ayaqhubeka nokushisa. Lokhu kungabangelwa yisifo noma isimo esiqhubeka ngokulimaza. Ngokwe-arthritis, isibonelo, ukuhlanganiswa kusesimweni sokuphazamiseka okuqhubekayo, okwenza izibonakaliso zobuhlungu zihambele ebuchosheni ngenkathi encane. Ngezinye izikhathi, ngisho nangaphandle kokulimala kwezicubu, i-nociceptors iyaqhubeka ishisa. Kungase kungabi yisisusa somzimba sobuhlungu, kodwa impendulo yobuhlungu ifana. Lokhu kwenza ubuhlungu obungapheliyo bunzima ukuyibeka phansi futhi kunzima nakakhulu ukwelapha.
