Ngaba ngamanye amaxesha uziva unesizungu, ungalungelelananga, okanye unesizungu? Okanye uhlala usiva isandi 'sokukhala...' ezindlebeni zakho? Okanye uziva ngathi ulahlekelwe kukuva? Usenokungazi ukuba kukho umthambo omncinci kodwa obaluleke kakhulu entlokweni yethu obandakanyeka kwezi zinto. Namhlanje siza kuthetha ngalo mthambo owenza umsebenzi omangalisayo emzimbeni wethu.
Ngamafutshane, yintoni iVestibulocochlear Nerve?
Oku kusenokuvakala ngathi ligama elide nelingaqhelekanga, kodwa ngenene kulula kakhulu. I-vestibulocochlear nerve yakho yi-nerve ethwala ulwazi ukusuka kwinxalenye engaphakathi yendlebe yakho ukuya ebuchotsheni bakho. Enyanisweni yindibaniselwano yamacandelo amabini. Cinga nge-nerve njengeentambo ezithwala imiqondiso yombane ukusuka kwelinye icala lomzimba wakho ukuya kwelinye.
Le nerve yenye yemithambo-luvo eli-12 ephambili entlokweni yethu. Siyibiza ngokuba yiCranial Neves . Kuyo, le yi -cranial nerve yesibhozo (Cranial Nerve VIII) . Imisebenzi yayo emibini ephambili kukusinceda sive kwaye sisincede sigcine ibhalansi yomzimba wethu.
Igama lale nerve lisinika ingcaciso ngemisebenzi emibini eyenzayo. Masiyihlalutye:
1. I-Vestibular: Oku kunxulumene nokulinganisela kwemizimba yethu.
2. Icandelo le-Cochlear: Oku kunxulumene nokukwazi kwethu ukuva izandi.
Ezi mithambo-luvo zimbini ziyadibana ukuze zenze umthambo wesibhozo wentloko, kodwa nganye yenza imisebenzi yayo eyahlukileyo.
| Inxalenye yemithambo-luvo | Umsebenzi ophambili |
|---|---|
| Umthambo weVestibular | Ithumela ulwazi engqondweni malunga nendawo kunye nokuhamba kwentloko yakho. Yiyo le nto igcina umzimba wakho ulungelelene. |
| Umthambo weCochlear | I-cochlea, inxalenye yendlebe engaphakathi, ithumela ulwazi oluvakalayo engqondweni. Yiyo le nto isenza sikwazi ukuva. |
Isebenza njani le mithambo-luvo? Makhe sijonge ngokusondeleyo.
Kuyamangalisa indlela ezisebenza ngayo ezi nxalenye zimbini.
I-vestibular nerve, elawula ibhalansi yomzimba
Khawuthelekelele ujika intloko yakho ngequbuliso uye ngasekhohlo. Ngaloo mzuzu, ulwelo olungaphakathi kwilungu lokulinganisela endlebeni yakho yangaphakathi luyashukuma. Olu shukumo luvuselela iiseli ezibuthathaka kakhulu apho, ludala isignali yombane.
- Inyathelo 1: Umyalezo uyaveliswa. Xa ushukumisa intloko yakho, ulwelo olukwindlebe yakho yangaphakathi luhamba nayo. Oku kudala umyalezo othi, "Intloko yakho ngoku ijike yajika ngale ndlela."
- Inyathelo lesi-2: Umyalezo uhamba ngemithambo-luvo. Lo myalezo uhamba ngemithambo-luvo ye-vestibular njengentambo ukuya kwisiseko sobuchopho .
- Inyathelo lesi-3: Ingqondo yenza izigqibo. Amaziko akhethekileyo kwisiseko sengqondo athatha olu lwazi aze enze oko kuyimfuneko ukugcina umzimba ulungelelene. Umzekelo, nokuba uhamba, ungafunda ngokucacileyo uphawu esitalatweni ngenxa yenkqubo ebizwa ngokuba yi-vestibulo-ocular reflex (VOR) , elawula iintshukumo zamehlo akho. Kwakhona, xa sele uza kuwa, ngequbuliso ubeka unyawo olunye phambi kwakho kwaye ulungelelane ngenxa yale miyalezo.
I-cochlear nerve esivumela ukuba sive
Siyiva njani ingoma? Le yinkqubo entle kakhulu.
- Inyathelo 1: Umyalezo uyaveliswa. Amaza esandi avela ngaphandle angena endlebeni yakho aze aye kwi -cochlea , inxalenye efana ne-snail yendlebe yangaphakathi. Amaza esandi abangela ukuba ulwelo kunye neeseli zeenwele ezincinci kakhulu ngaphakathi kwi-cochlea zingcangcazele. Ezi ntshukumo ziyatshintsha ngokuxhomekeke kwisandi kunye nesandi esikhulu. Oku kudala umyalezo wombane malunga nesandi.
- Inyathelo lesi-2: Umyalezo uhamba ngemithambo-luvo. Lo myalezo uhamba ngemithambo-luvo ye-cochlear uye kwisiseko sobuchopho.
- Inyathelo lesi-3: Ingqondo itolika isandi. Iziko lokuva elikwisiseko sengqondo lithumela lo myalezo kwinxalenye yengqondo ecubungula isandi. Kulapho ingqondo iqonda khona ukuba yingoma, umntu othethayo, okanye esinye isandi.
Ziziphi iimeko kunye neempawu eziqhelekileyo ezichaphazela le mithambo-luvo?
Ukuba kukho nawuphi na umonakalo kwimithambo-luvo eyenza umsebenzi obaluleke kangaka, unokuba nefuthe elikhulu kubomi bethu bemihla ngemihla.
Izizathu ezinokubakho zomonakalo wemithambo-luvo:
- Ukulimala entloko: Ukulimala kakhulu entlokweni, ingakumbi ezijikeleze iindlebe.
- Iimeko zokuzalwa: Abanye abantwana basenokungakhuli kakuhle le mithambo-luvo xa bezalwa.
- Iithumba: Iithumba ezingezizo ezomhlaza (ezingenobungozi), ingakumbi ii-acoustic neuromas, zinokwakheka kule nerve zize zibangele uxinzelelo.
- Izifo: Izifo ezibangelwa ziintsholongwane ezifana ne -vestibular neuritis okanye i-labyrinthitis zinokubangela ukudumba kwale mithambo-luvo.
Eyona nto ibalulekileyo kukuba ukuba unenye okanye ngaphezulu kwezi mpawu, ungazityesheli kwaye ubone ugqirha wakho ngokukhawuleza.
Iimpawu zokuba kukho ingxaki:
Xa le mithambo-luvo yonakele, kuvela iingxaki zokuva nokulinganisela. Le theyibhile ingezantsi ikunceda ukuba uqonde ezi mpawu ngokucacileyo.
| Uphawu | Kalula nje... |
|---|---|
| Ukulahlekelwa kukuva nge-sensorineural | Ukulahlekelwa kukuva ngenxa yomonakalo kwindlebe yangaphakathi okanye kwimithambo-luvo. |
| I-tinnitus | Isandi esihlala sinkenteza ezindlebeni, nokuba akukho sandi sijikelezayo. |
| Isiyezi | Ukuziva ungalungelelananga, unesiyezi, unentloko ebuhlungu. |
| I-Vertigo | Uvakalelo olunamandla lokuba wena okanye igumbi okulo liyajikeleza, nokuba umile nje. Oku kunokwenzeka naxa uvuka ebhedini kusasa. |
| I-Nystagmus | Amehlo akho ahamba ngokukhawuleza okanye anyuke aze ehle ngaphandle kolawulo lwakho. |
Ugqirha uyifumanisa njani le ngxaki?
Xa usiya kugqirha oneempawu ezinjalo, kusenokwenzeka ukuba uza kwenza iimvavanyo ezininzi ukuze afumane unobangela.
- Uvavanyo lokuva: Ugqirha wakho angenza uvavanyo olulula njengovavanyo lukaRinne kunye novavanyo lukaWeber , olubandakanya ukubeka isixhobo esincinci sokungcangcazela (ifolokhwe yokulungisa) entlokweni yakho nakufutshane nendlebe yakho kwiindawo ezahlukeneyo ukuze kuvavanywe amandla akho okuva izandi.
- Uvavanyo lweVestibular: Ukulinganisela kwakho, ukuhamba, kunye nokuhamba kwamehlo (ukujonga i-nystagmus) kunokuhlolwa.
- Uvavanyo lokujonga imifanekiso: Ngamanye amaxesha, ukuba kukho into erhanelekayo efana neqhuma, kunokuyalelwa i -CT scan (i-Computed Tomography scan) okanye i-MRI scan (i-Magnetic Resonance Imaging) . Ezi zinokuvelisa imifanekiso ecacileyo yangaphakathi kwentloko kunye nendawo ejikeleze indlebe.
Wenza ntoni njengonyango?
Unyango luxhomekeke kwisizathu seempawu zakho.
- Amayeza: Ukuba imeko ibangelwa lusulelo, ugqirha wakho unokukunika amayeza okulwa neentsholongwane okanye ii-corticosteroids , ezinciphisa ukudumba kwimithambo-luvo.
- Utyando: Ukuba ithumba licinezela umthambo, kunokufuneka utyando ukuze kususwe ithumba.
- Unyango lokubuyisela umzimba kwi-Vestibular: Oku kufana nonyango lomzimba. Ukuba uneengxaki eziqhubekayo ngokulinganisela kwakho, ugqirha unokukunika umthambo okhethekileyo ukukunceda ubuyisele ukulinganisela.
Siyikhusela njani le mithambo-luvo ixabisekileyo?
Asinakuyithintela rhoqo ingozi okanye ukwenzakala, kodwa kukho izinto esinokuzenza ukugcina indlebe yethu yangaphakathi kunye nalo mthambo uphilile.
- Ziphephe iingxolo ezinkulu: Ukuvezwa kwingxolo enkulu kunokonakalisa iiseli ezibuthathaka kwindlebe yangaphakathi. Ngoko ke, sebenzisa ii-earplugs ukuba ukwiindawo ezinengxolo enkulu.
- Fumana unyango lwezifo zendlebe ngokukhawuleza: Ukuba uva iintlungu zendlebe okanye ukuphuma kwamanzi emzimbeni, musa ukuzityeshela kwaye udibane nogqirha ngoko nangoko.
- Indlela yokuphila enempilo: Ukutya okunesondlo kunye nendlela yokuphila esebenzayo zilungile kumzimba wonke nakwinkqubo yemithambo-luvo.
I-vestibulocochlear nerve ifana nebhulorho ebaluleke kakhulu esinceda sifumane amava ehlabathi. Ngaphandle kwayo, besingenakukwazi ukonwabela ingoma okanye ukuhamba ngokulinganisela. Ngoko ke masiyinyamekele le mithambo-luvo incinci ebonakala ngathi yenza umsebenzi omkhulu.
Umyalezo Wokuya Ekhaya
- I-vestibulocochlear nerve yakho inemisebenzi emibini ephambili: ukuva nokugcina ibhalansi .
- Ukudinwa ngequbuliso (vertigo), ukukhala ezindlebeni (tinnitus), okanye ukulahleka kokuva kungaba ziimpawu zengxaki yalo mthambo.
- Musa ukuzityeshela iimpawu ezifana nezi kuba "ziya kuphela emva kwexesha elifutshane." Ngamanye amaxesha, inokuba luphawu lokuqala lwesifo esinzima.
- Ukuba unamathandabuzo nokuba mancinci kangakanani ngale nto, eyona nto ingcono onokuyenza kukubona ugqirha wakho ngokukhawuleza kwaye ucele ingcebiso.
