Masifunde ngakumbi ngenkqubo ye-vestibular, inkqubo ephezulu egcina ibhalansi yomzimba wakho!

Sonke siyazi ukuba imizimba yethu inamandla amangalisayo okuhamba, ukubaleka, ukutsiba, kunye nokuma nkqo. Kodwa ngaba wakha wazibuza ukuba sikwenza njani konke oku, sihlala njani nkqo? Yiloo nto inkqubo ekhethekileyo, encinci kodwa ebaluleke kakhulu emzimbeni wethu inceda kuyo. Yile nto siyibiza ngokuba yinkqubo ye-vestibular . Ngamafutshane, le yinkqubo enceda kakhulu ukugcina ukulingana kwemizimba yethu, oko kukuthi, ukulinganisela.

Yintoni inkqubo ye-vestibular? Ngamafutshane...

Cinga ngayo, nokuba simi nje, sihlala sihamba nehlabathi elisingqongileyo. Xa le nkqubo ye-vestibular isebenza kakuhle, ixelela umzimba wakho indlela ohamba ngayo, indlela izinto ezikujikelezileyo ezihamba ngayo, kwaye inceda ukugcina ibhalansi yakho, okanye ibhalansi yomzimba wakho, izinzile.

Le nkqubo ineenxalenye ezimbini eziphambili:

• Inkqubo ye-vestibular ejikeleze umzimba: Yile nto abantu abaninzi abayithethayo xa besithi "inkqubo ye-vestibular." Iqulathe amalungu amahlanu eemvakalelo endlebeni yakho yangaphakathi. La malungu anika ulwazi malunga nendlela oma ngayo, indawo omi kuyo, kunye nentshukumo ebalulekileyo ekulinganiseni umzimba wakho.
• Inkqubo ye-vestibular esembindini: Le yinxalenye yenkqubo yakho ye-nervous central (CNS). Isebenza ngokulinganisela imiqondiso evela kwizitho ze-vestibular ezisendlebeni yakho yangaphakathi.

Isebenza njani le nto? Uyenza njani ibhalansi emzimbeni wakho?

Inkqubo yakho ye-vestibular yinxalenye ebaluleke kakhulu yenkqubo yeemvakalelo eyinkimbinkimbi ekunceda ugcine ibhalansi yakho. Isinceda sihlale sime nkqo xa sihamba, sibaleka, kwaye ekugqibeleni sime nkqo.

Nantsi into eyenzekayo:

Inkqubo ye-vestibular ekwindlebe yakho yangaphakathi ibona iintshukumo zentloko yakho. Emva koko ithumela olu lwazi engqondweni yakho. Ezi ntshukumo zikunika ulwazi malunga nokuba ukuphi kwaye unjani ngokunxulumene nendawo ekungqongileyo. Ingqondo yakho idibanisa olu lwazi nolwazi lweemvakalelo oluvela emehlweni akho kunye nolwazi lweemvakalelo oluvela kwimisipha kunye namalungu akho. Amehlo akho akunceda ukuba umisele indawo yakho ngokusekelwe kwinto oyibonayo. Imisipha kunye namalungu akho akwabonelela ngolwazi lweemvakalelo malunga nokuba adibana nini nendawo ekungqongileyo.

Khawucinge uhamba kumhlaba ongalinganiyo. Ukuba ngequbuliso ubethe ilitye elincinci ngonyawo lwakho, ubungayi kuwa kwangoko, akunjalo? Umzimba wakho ubuya kushukuma kancinci uze uqonde kwakhona. Ngaloo mzuzu, amehlo akho, inkqubo ye-vestibular ezindlebeni zakho, kunye nemisipha emilenzeni yakho zonke ziyahlangana ukuze zikusindise.

Ngokusekelwe kwezi zinto zintathu zifakwayo (inkqubo ye-vestibular + amehlo + izihlunu kunye namalungu), ingqondo yakho ithumela imiyalezo emzimbeni wakho malunga nendlela yokugcina ibhalansi.

I-reflexes yenkqubo ye-vestibular iyamangalisa!

Inkqubo ye-vestibular ayilolungu elahlukileyo nje kuphela. Inxulumene ngokusondeleyo namehlo akho, izihlunu kunye namalungu, kwaye ilungelelanisa ngokuzenzekelayo imisebenzi elawula ulungelelwaniso. Ii-reflexes ezimbini eziphambili zinceda koku:

• I-Vestibulo-ocular reflex (VOR): Amehlo akho kunye nenkqubo ye-vestibular zisebenza kunye ukugcina amehlo akho kwindawo enye nokuba uhamba. Khawuthelekelele ubaleka usiya kwindawo ekujoliswe kuyo. Nangona ushukumisa intloko yakho ukusuka kwelinye icala ukuya kwelinye, amehlo akho asekwindawo ekujoliswe kuyo, akunjalo? Awutsibi xa ubaleka. Kungenxa yale reflex ebizwa ngokuba yi-VOR . Oko kukuthi, amehlo akho ahamba kwicala elahlukileyo lentshukumo yentloko yakho ukuze ugcine amehlo akho eqinile. Ngaphandle koku, ungaziva unesizungu kwaye uwe lula.

• I-Vestibulospinal reflex (VS reflex): Izihlunu zakho zilungelelanisa ngokuzenzekelayo utshintsho kwinkqubo yakho ye-vestibular. Khawuthelekelele uhamba kwindlela engalinganiyo, enamatye. Njengoko intloko yakho ishukuma kancinci, inkqubo yakho ye-vestibular ibona utshintsho kwindlela omi ngayo. Ngelo xesha, i -VS reflex itshintsha ubunzima bomzimba wakho ukuze ibuyisele, ikugcine ungakhubeki.

Iphi le nkqubo ye-vestibular?

Izitho zomzimba zenkqubo yakho ye-vestibular zikwindlebe yakho yangaphakathi . Indlebe yakho yangaphakathi ikwalikhaya le-cochlea, ekuncedayo ukuva. Kukho enye inxalenye yendlebe yangaphakathi ebizwa ngokuba yi-vestibular labyrinth . Ngaphakathi apho kulapho izitho zakho ezintlanu ze-vestibular (ezikwabizwa ngokuba yi-"vestibular apparatus") zikhoyo.

La malungu ayayibona indawo yentloko yakho aze athumele imiqondiso kwiindawo zengqondo ezikunceda ugcine ulungelelwano.

Ziziphi iindawo zenkqubo ye-vestibular?

Kukho amalungu amahlanu aphambili e-vestibular kwisixhobo se-vestibular esikwindlebe yakho yangaphakathi:

• Iimisele ezintathu ezisisiqingatha sesangqa
• Amalungu amabini e-otolith

Isixhobo se-vestibular, esiqulathe la malungu, sizaliswe lulwelo olubizwa ngokuba yi-endolymph kunye neeseli ezincinci ezifana neenwele ezibizwa ngokuba zii-hair cell sensory receptors. Xa intloko yakho ishukuma, le endolymph ihamba isiya phambili nangasemva. Iiseli zeenwele emva koko zihamba nayo. Ngenxa yale ntshukumo, iiseli zithumela ulwazi lweemvakalelo malunga nentshukumo yakho engqondweni. Ezi zimpawu zemithambo-luvo zihamba ngemithambo-luvo ebalulekileyo ebizwa ngokuba yi-vestibular nerve (ekwabizwa ngokuba yi-vestibulocochlear nerve okanye i-8th cranial nerve).

Imijelo ejikelezayo

Ezi ziityhubhu ezintathu ezikwindlebe yakho yangaphakathi ezibona iintshukumo zentloko ezijikelezayo.

• Umjelo oPhezulu:Bayazazi iintshukumo zentloko (njengokunqwala ukuze bathi "ewe").
• Umjelo othe tye: Ubona iintshukumo zentloko ukusuka ekhohlo ukuya ekunene (njengokushukumisa intloko yakho ukuze uthi "hayi").
• Umjelo ongasemva: Ubona iintshukumo ezigoba intloko ukusuka kwelinye icala ukuya kwelinye (njengokujika intloko iye ecaleni).

Umjelo ngamnye uphela ngesakhiwo esibizwa ngokuba yi-ampulla . Ngaphakathi kweli candelo kukho iiseli zeenwele, ezisasazeke kwi-substance efana nejeli ebizwa ngokuba yi-cupula . Xa ushukumisa intloko yakho, ulwelo lwe-endolymph ngaphakathi kwimijelo ye-semicircular luhamba ngasemva nangaphambili. Iiseli zeenwele ngaphakathi kwi-cupula zihamba nayo. Le ntshukumo ithumela imiqondiso yemithambo-luvo engqondweni, iyixelele apho intloko yakho ikhoyo.

Izitho ze-Otolith

La ngamagumbi amabini aqaphela iintshukumo ezithe ngqo ezinxulumene nomxhuzulane.

• I-Utricle: Ibona iintshukumo ezithe tye (phambili okanye ngasemva, njengaxa ukhwela emotweni).
• I-Saccule: Ibona iintshukumo ezithe nkqo (phezulu okanye ezantsi, njengaxa ukhwela ilifti).

Isitho ngasinye se-otolith sinesakhiwo esibizwa ngokuba yi-macula . Le macula ikwanazo neeseli zeenwele. Zifakwe kwi-substance efana nejeli ebizwa ngokuba yi-otoconia, ezaliswe ziikristale ze-calcium. Xa ushukuma, ezi otoconia ngaphakathi kwezitho ze-otolith zihamba zibuyela umva. Iiseli zeenwele emva koko zihamba nazo. Le ntshukumo ithumela imiqondiso yemithambo-luvo engqondweni.

Ziziphi izifo ezichaphazela inkqubo ye-vestibular?

Ngelishwa, nale nkqubo imangalisayo ngamanye amaxesha inokuba neengxaki. Kulapho ke izinto ezifana nesiyezi kunye nokuquleka zinokwenzeka khona. Kukho iindawo ezimbini eziphambili apho iingxaki zinokwenzeka khona:

Ezona ngxaki zixhaphakileyo ze-peripheral (indlebe yangaphakathi) ze-vestibular zezi:

• I-Benign Paroxysmal Positional Vertigo (BPPV) : Kulapho iibhola ezincinci ezibizwa ngokuba yi-otoconia ngamanye amaxesha zingena kwimisele. Oku kubangela isiyezi esinzima xa ushukumisa intloko yakho.
• I-Labyrinthitis : Usulelo okanye ukudumba kwesixhobo se-vestibular sendlebe yangaphakathi.
• Isifo sikaMénière : Imeko ebangelwa kukunyuka koxinzelelo lolwelo endlebeni engaphakathi. Iimpawu zingabandakanya ukulahlekelwa kukuva, ukukhala ezindlebeni, kunye nesiyezi.
• I-Vestibular neuritis: Ukudumba kwemithambo-luvo ye-vestibular.

Izifo ze-vestibular eziphambili zixhaphakileyo zezi:

• Isifo seMal de débarquement (MdDS) : Ukuziva ngathi usashukuma emva kokuphuma enqanaweni okanye esikhepheni.
• Isiyezi Esiqhubekayo Sokubona Izinto Ezingasemva Kwengqondo (PPPD): Isiyezi esingapheliyo ekunzima ukufumana unobangela waso.
• Iintloko ezibuhlungu zeVestibular : Isiyezi esihamba neentloko ezibuhlungu.

Uyazi njani ukuba kukho ingxaki kwinkqubo ye-vestibular? Zithini iimpawu?

Iimpawu eziphambili zeengxaki zokulinganisela kukuba nesiyezi kunye ne-vertigo . Zombini ezi zinto zinokubangela ukungonwabi kunye nobunzima bokuma, kodwa zahlukile kancinci.

Ukuba unesiyezi, ungaziva:

• I-Woozy
• Ndikhaphukhaphu, ndiziva ndikhaphukhaphu
• Ukuziva udidekile, ungakwazi ukuqonda ukuba ukuphi (Udidekile)

Ukuba une "vertigo" (isiyezi/ukujikeleza okukhulu), ungaziva:

• Kuvakala ngathi uyajikeleza nangona umile nje.
• Ukuziva ngathi ihlabathi liphela liyakujikeleza.

Abanye abantu bathi, "Ndiziva ndinesizungu." Kusenokuba sisizungu, okanye kungaba yi-vertigo. Kwi-vertigo, uhlala uziva ngathi wena okanye indawo ekungqongileyo iyajikeleza. Kufana nokuba ukwithoyi ejikelezayo.

Kunye nezi mpawu, kuxhomekeke kwimeko ethile ye-vestibular onayo, unokufumana nezinye iimpawu ezichaphazela ukuva kwakho kunye nokubona. Ngenxa yokuba inkqubo yakho ye-vestibular iqhagamshelwe ngokusondeleyo namehlo neendlebe zakho (izitho eziphambili zemvakalelo nazo zikwindlebe yangaphakathi), ezi ngxaki ngamanye amaxesha zinokudibana.

Ungayijonga njani impilo yenkqubo ye-vestibular?

Eyona ndlela iphambili oogqirha abaxilonga ngayo iimeko ze-vestibular kukuvavanya i-vestibular . Oku kubandakanya ukwenza iimvavanyo ezininzi ukujonga impilo yenkqubo yakho ye-vestibular. Uninzi lwezi vavanyo lujonga indlela amehlo akho kunye nenkqubo ye-vestibular ezisebenzisana ngayo ukugcina ibhalansi (yileyo i-VOR esithethe ngayo ngaphambili).

Kusenokufuneka wenze uvavanyo lwegazi ukuze ujonge usulelo, okanye uvavanyo lwemifanekiso (umz., i-MRI scan) ukuze ujonge iingxaki zesakhiwo ezichaphazela inkqubo yakho ye-vestibular.

Ziziphi iindlela zonyango zenkqubo ye-vestibular?

Iimeko ezininzi ze-vestibular zifuna indibaniselwano yonyango, oko kuthetha ukuba kukho iindlela zonyango ezingaphezu kwesinye.

• Utshintsho kwindlela yokuphila: Ukunciphisa izinto ezifana noxinzelelo olubangela isiyezi.
• Unyango lomzimba lweVestibular: Oku kunokunceda ukunciphisa iimpawu, kuqinise izakhiwo ezibuthathaka ezifana ne-VOR, okanye kwenziwe iindlela ezithile zokutshintsha indawo yezigulane kwiimeko ezifana ne-BPPV.
• Amayeza: Amayeza anokunikwa ukunyanga usulelo okanye ukunciphisa iimpawu zesiyezi, ezifana nokucaphuka.
• Utyando:Ngamanye amaxesha, utyando lunokufuneka ukuze kulungiswe izakhiwo ezikwindlebe engaphakathi ezibangela ingxaki. Nangona kunjalo, oku kudla ngokuba yindlela yokugqibela.

Singayigcina njani le nkqubo ye-vestibular isempilweni?

Enyanisweni, iingxaki ezininzi ze-vestibular kunzima ukuzithintela. Nangona kunjalo, ungayinyamekela inkqubo yakho ye-vestibular (kunye nawe) ngokufuna unyango ngokukhawuleza xa kukho iimpawu zokuqala zengxaki.

Umzekelo, ezinye iimeko, ezinje ngosulelo lwendlebe yangaphakathi, zinokuphola ngokuhamba kwexesha, kodwa zingonakalisa iiseli zeenwele ezibuthathaka ngaphakathi kwendlebe yakho. Xa ezi seli zonakele, azikwazi ukukhula kwakhona. Yiyo loo nto kubalulekile ukufumana unyango ngokukhawuleza.

Uyilinganisa njani inkqubo ye-vestibular?
