Ingabe ngezinye izikhathi uzizwa unesizungu, ungalingani kahle, noma unesizungu? Noma ingabe uhlala uzwa umsindo 'wokukhala...' ezindlebeni zakho? Noma uzizwa sengathi ulahlekelwe ukuzwa ngokuzumayo? Ungase ungazi ukuthi kukhona inzwa encane kodwa ebaluleke kakhulu ekhanda lethu ehilelekile kulezi zinto. Namuhla sizokhuluma ngale nzwa eyenza umsebenzi omangalisayo emzimbeni wethu.
Kalula nje, iyini i-Vestibulocochlear Nerve?
Lokhu kungase kuzwakale njengegama elide nelingavamile, kodwa empeleni kulula kakhulu. I-vestibulocochlear nerve yakho iyi-nerve ethwala ulwazi oluvela engxenyeni engaphakathi yendlebe yakho iye ebuchosheni bakho. Empeleni iyinhlanganisela yezingxenye ezimbili. Cabanga nge-nerve njengezintambo ezithwala izimpawu zikagesi ezivela engxenyeni eyodwa yomzimba wakho ziye kwenye.
Lo mthambo ungomunye wemizwa eyi-12 eyinhloko ekhanda lethu. Siwubiza ngokuthi i-Cranial Neverves . Kulawa, lo mthambo wesishiyagalombili we-cranial (Cranial Nerve VIII) . Imisebenzi yawo emibili eyinhloko ukusisiza ukuzwa nokusisiza silondoloze ibhalansi yemizimba yethu.
Igama lalo mthambo linikeza inkomba yemisebenzi emibili oyenzayo. Ake siwuchaze:
1. I-Vestibular: Lokhu kuhlobene nokulinganisela kwemizimba yethu.
2. Ingxenye ye-Cochlear: Lokhu kuhlobene nekhono lethu lokuzwa imisindo.
Lezi zinzwa ezimbili ziyahlangana ukuze zakhe inzwa yesishiyagalombili ye-cranial, kodwa ngayinye yenza imisebenzi yayo ehlukile.
| Ingxenye yenzwa | Umsebenzi oyinhloko |
|---|---|
| Inzwa ye-Vestibular | Ithumela ulwazi ebuchosheni mayelana nendawo kanye nokunyakaza kwekhanda lakho. Yilokhu okugcina umzimba wakho ulinganisela. |
| I-cochlear nerve | I-cochlea, ingxenye yendlebe engaphakathi, ithumela ulwazi lomsindo ebuchosheni. Yilokhu okusenza sikwazi ukuzwa. |
Lo mthambo usebenza kanjani? Ake sibheke kabanzi.
Kuyamangalisa ukuthi lezi zingxenye ezimbili zisebenza kanjani.
I-vestibular nerve, elawula ibhalansi yomzimba
Zicabange ngokuzumayo uphendula ikhanda lakho ngakwesobunxele. Ngaleso sikhathi, uketshezi olungaphakathi kwesitho sokulinganisela endlebeni yakho yangaphakathi luyanyakaza. Lokhu kunyakaza kuvuselela amangqamuzana azwela kakhulu lapho, kudala isignali kagesi.
- Isinyathelo 1: Umlayezo uyakhiqizwa. Uma uhambisa ikhanda lakho, uketshezi olusendlebeni yakho yangaphakathi luhamba nalo. Lokhu kudala umyalezo othi, "Ikhanda lakho seliphenduke ngale ndlela."
- Isinyathelo sesi-2: Umlayezo uhamba ngemithambo. Lo mlayezo uhamba ngemithambo ye-vestibular njengekhebula eliya esiqwini sobuchopho .
- Isinyathelo 3: Ubuchopho benza izinqumo. Izikhungo ezikhethekile ohlelweni lobuchopho zithatha lolu lwazi futhi zenze okudingekayo ukugcina umzimba ulinganisele. Isibonelo, ngisho nalapho uhamba, ungafunda ngokucacile uphawu emgwaqweni ngenxa yenqubo ebizwa ngokuthi i-vestibulo-ocular reflex (VOR) , elawula ukunyakaza kwamehlo akho. Futhi, lapho usuzowa, ngokuzumayo ubeka unyawo olulodwa phambi kwakho futhi ulinganisele ngenxa yale miyalezo.
I-cochlear nerve esivumela ukuthi sizwe
Siyizwa kanjani ingoma? Lena futhi inqubo emangalisayo kakhulu.
- Isinyathelo 1: Umlayezo uyakhiqizwa. Amaza omsindo avela ngaphandle angena endlebeni yakho bese eya ku -cochlea , ingxenye efana ne-snail yendlebe yangaphakathi. Amaza omsindo abangela ukuthi uketshezi kanye namaseli ezinwele amancane kakhulu ngaphakathi kwe-cochlea anyakaze. Lokhu kunyakaza kuyashintsha kuye ngokuthi umsindo uzwakala kanjani kanye nomsindo kangakanani. Lokhu kudala umyalezo kagesi mayelana nomsindo.
- Isinyathelo sesi-2: Umlayezo uhamba ngemithambo. Lo myalezo uhamba ngemithambo ye-cochlear uye esiqwini sobuchopho.
- Isinyathelo 3: Ubuchopho buchaza umsindo. Izikhungo zokuzwa ezisesiqwini sobuchopho zithumela lo mlayezo engxenyeni yobuchopho ecubungula umsindo. Yilapho ubuchopho buqonda khona ukuthi ingoma, othile okhulumayo, noma omunye umsindo.
Yiziphi izimo nezimpawu ezivamile ezithinta lo mthambo?
Uma kukhona umonakalo emsipheni owenza umsebenzi obaluleke kangaka, kungaba nomthelela omkhulu empilweni yethu yansuku zonke.
Izimbangela ezingaba khona zokulimala kwemizwa:
- Ukulimala ekhanda: Ukulimala okukhulu ekhanda, ikakhulukazi eduze kwezindlebe.
- Izimo zokuzalwa: Ezinye izingane zingase zingakhuli kahle le nzwa lapho zizalwa.
- Izimila: Izimila ezingezona ezomdlavuza (ezingenobungozi), ikakhulukazi ama-neuromas e-acoustic, zingakheka kule nerve futhi zibangele ingcindezi.
- Ukutheleleka: Ukutheleleka ngegciwane njenge- vestibular neuritis noma i-labyrinthitis kungabangela ukuvuvukala kwale nerve.
Into ebaluleke kakhulu ukuthi uma unesinye noma ngaphezulu salezi zimpawu, ungazinaki futhi ubone udokotela wakho ngokushesha okukhulu.
Izimpawu zokuthi kunenkinga:
Uma lo mthambo ulimele, kuvela izinkinga zokuzwa nokulinganisela. Ithebula elingezansi likusiza ukuthi uqonde lezi zimpawu ngokucacile.
| Isibonakaliso | Kalula nje... |
|---|---|
| Ukulahlekelwa ukuzwa kwe-sensorineural | Ukulahlekelwa ukuzwa ngenxa yokulimala kwendlebe yangaphakathi noma imizwa. |
| I-tinnitus | Umsindo ohlala ukhala ezindlebeni, noma ngabe akukho msindo ozungezile. |
| Isiyezi | Ukuzizwa ungalingani, unesiyezi, unekhanda elibuthakathaka. |
| I-Vertigo | Umuzwa onamandla wokuthi wena noma igumbi okulo liyajikeleza, noma ngabe umile nje. Lokhu kungenzeka ngisho nalapho uvuka embhedeni ekuseni. |
| I-Nystagmus | Amehlo akho ahamba ngokushesha emuva naphambili noma phezulu naphansi ngaphandle kokulawula kwakho. |
Udokotela uyixilonga kanjani le nkinga?
Uma uya kudokotela onalezi zimpawu, cishe uzokwenza izivivinyo eziningana ukuthola imbangela.
- Ukuhlolwa kokuzwa: Udokotela wakho angenza ukuhlolwa okulula njengokuhlolwa kukaRinne kanye nokuhlolwa kukaWeber , okuhlanganisa ukubeka ithuluzi elincane elidlidlizayo (ifoloko lokulungisa) ekhanda lakho naseduze kwendlebe yakho ezindaweni eziningana ukuze ahlole ikhono lakho lokuzwa imisindo.
- Ukuhlolwa kwe-Vestibular: Ibhalansi yakho, ukuhamba, kanye nokunyakaza kwamehlo (ukuhlola i-nystagmus) kungahlolwa.
- Ukuhlolwa kwezithombe: Ngezinye izikhathi, uma kukhona okusolwayo ngento efana neqhubu, kungacelwa i -CT scan (i-Computed Tomography scan) noma i-MRI scan (i-Magnetic Resonance Imaging) . Lokhu kungaveza izithombe ezicacile zangaphakathi kwekhanda nendawo ezungeze indlebe.
Wenzani njengokwelashwa?
Ukwelashwa kuncike embangela yezimpawu zakho.
- Imithi: Uma lesi simo sibangelwa ukutheleleka, udokotela wakho angase akunikeze imithi yokulwa namagciwane noma ama-corticosteroids , anciphisa ukuvuvukala emthanjeni.
- Ukuhlinzwa: Uma isimila sicindezela inzwa, kungase kudingeke ukuhlinzwa ukuze kususwe isimila.
- Ukwelashwa kokuvuselelwa kwe-Vestibular: Lokhu kufana nokwelashwa ngokomzimba. Uma unezinkinga eziqhubekayo ngokulinganisela kwakho, udokotela angase akunikeze izivivinyo ezikhethekile ukuze akusize uphinde uthole ibhalansi.
Siyivikela kanjani le nzwa eyigugu?
Asikwazi ukuvimbela izingozi noma ukulimala ngaso sonke isikhathi, kodwa kunezinto esingazenza ukuze sigcine indlebe yethu yangaphakathi kanye nale nzwa iphilile.
- Gwema imisindo emikhulu: Ukuchayeka emisindweni emikhulu kungalimaza amangqamuzana azwelayo endlebeni yangaphakathi. Ngakho-ke, sebenzisa ama-earplug uma usezindaweni ezinomsindo omkhulu.
- Thola ukwelashwa kwezifo zendlebe ngokushesha: Uma uzwa ubuhlungu bendlebe noma ukuphuma kwegazi, ungakushayi indiva bese ubona udokotela ngokushesha.
- Indlela yokuphila enempilo: Ukudla okunempilo kanye nendlela yokuphila esebenzayo kuhle emzimbeni wonke kanye nasesimisweni sezinzwa.
I-vestibulocochlear nerve ifana nebhuloho elibaluleke kakhulu elisisiza ukuba sizizwele umhlaba. Ngaphandle kwayo, besingeke sikwazi ukujabulela ingoma noma ukuhamba ngokulinganisela. Ngakho-ke masinakekele le mizwa ebonakala incane eyenza umsebenzi omkhulu.
Umlayezo Wokuya Nawe Ekhaya
- Inzwa yakho ye-vestibulocochlear inemisebenzi emibili eyinhloko: ukuzwa nokugcina ibhalansi .
- Ukuzungeza okungazelelwe (vertigo), ukukhala ezindlebeni (tinnitus), noma ukulahlekelwa ukuzwa kungaba izimpawu zenkinga yalo mthambo.
- Ungazinaki izimpawu ezinjengalezi ngoba "zizodlula ngesikhashana." Ngezinye izikhathi, zingaba uphawu lokuqala lwesifo esibucayi.
- Uma unokungabaza okuncane ngalokhu, into engcono kakhulu ongayenza ukubonana nodokotela wakho ngokushesha okukhulu bese ucela iseluleko.
