Ake sifunde kabanzi ngesistimu ye-vestibular, uhlelo oluhle kakhulu olugcina ibhalansi yomzimba wakho!

Sonke siyazi ukuthi imizimba yethu inekhono elimangalisayo lokuhamba, ukugijima, ukugxuma, kanye nokuma uqonde. Kodwa wake wazibuza ukuthi sikwenza kanjani konke lokhu, ukuthi sihlala kanjani siqonde? Yilokho uhlelo olukhethekile kakhulu, oluncane kodwa olubaluleke kakhulu emzimbeni wethu olusiza ngakho. Yilokhu esikubiza ngokuthi uhlelo lwe-vestibular . Kalula nje, lolu uhlelo olusiza kakhulu ekugcineni ukulingana kwemizimba yethu, okungukuthi, ibhalansi.

Iyini isistimu ye-vestibular? Kalula nje...

Cabanga ngakho, noma ngabe simi nje, sihlala sihamba nomhlaba osizungezile. Uma lolu hlelo lwe-vestibular lusebenza kahle, lutshela umzimba wakho ukuthi uhamba kanjani, ukuthi izinto ezikuzungezile zihamba kanjani, futhi lusiza ekugcineni ibhalansi yakho, noma ibhalansi yomzimba wakho, izinzile.

Lolu hlelo lunezingxenye ezimbili eziyinhloko:

• Uhlelo lwe-vestibular oluseceleni: Yilokhu abantu abaningi abakushoyo ngempela uma bethi "uhlelo lwe-vestibular." Luqukethe izitho ezinhlanu zokuzwa endlebeni yakho yangaphakathi. Lezi yizo ezinikeza ulwazi mayelana nokuma kwakho, isikhundla, kanye nokunyakaza okubalulekile ekulinganiseni komzimba wakho.
• Uhlelo lwe-vestibular oluphakathi: Lokhu kuyingxenye yesistimu yakho yezinzwa ephakathi (i-CNS). Lucubungula izimpawu zokulinganisela ezivela ezithweni ze-vestibular endlebeni yakho yangaphakathi.

Kusebenza kanjani lokhu? Ukwakha kanjani ibhalansi emzimbeni wakho?

Uhlelo lwakho lwe-vestibular luyingxenye ebaluleke kakhulu yesistimu yezinzwa eyinkimbinkimbi ekusiza ukuthi ugcine ibhalansi yakho. Lusisiza ukuthi sihlale siqonde lapho sihamba, sigijima, futhi ekugcineni sime siqonde.

Yilokhu okwenzekayo:

Uhlelo lwe-vestibular olusendlebeni yakho yangaphakathi luthola ukunyakaza kwekhanda lakho. Lube seluthumela lolu lwazi ebuchosheni bakho. Lokhu kunyakaza kukunikeza ulwazi mayelana nokuthi ukuphi nokuthi ukuphi maqondana nendawo okuzungezile. Ubuchopho bakho buhlanganisa lolu lwazi nolwazi lwezinzwa oluvela emehlweni akho kanye nolwazi lwezinzwa oluvela emisipheni nasemalungeni akho. Amehlo akho akusiza ukuthi unqume indawo yakho ngokusekelwe kulokho okubonayo. Imisipha namalunga akho nawo ahlinzeka ngolwazi lwezinzwa mayelana nokuthi angqubuzana nini nendawo okuzungezile.

Cabanga uhamba endaweni engalingani. Uma ungashayisa itshe elincane ngonyawo lwakho ngokuzumayo, ubungeke uwe ngokushesha, akunjalo? Umzimba wakho ubuzonyakaza kancane bese uqonda futhi. Ngaleso sikhathi, amehlo akho, uhlelo lwe-vestibular ezindlebeni zakho, kanye nemisipha emilenzeni yakho konke kuyahlangana ukuze kukusindise.

Ngokusekelwe kulezi zinto ezintathu ezifakwayo (uhlelo lwe-vestibular + amehlo + imisipha namalunga), ubuchopho bakho buthumela izimpawu emzimbeni wakho zokuthi ungalondoloza kanjani ibhalansi.

Ukusabela kwesistimu ye-vestibular kuyamangalisa!

Uhlelo lwe-vestibular aluyona nje isitho esihlukile. Luxhumene eduze namehlo akho, imisipha, kanye namalunga, futhi luhlanganisa ngokuzenzakalelayo imisebenzi elawula ibhalansi. Ama-reflex amabili ayinhloko asiza kulokhu:

• I-Vestibulo-ocular reflex (VOR): Amehlo akho kanye nesistimu ye-vestibular zisebenza ndawonye ukugcina amehlo akho endaweni eyodwa ngisho nalapho uhamba. Zicabange ugijimela endaweni ethile. Ngisho noma uhambisa ikhanda lakho kusukela kolunye uhlangothi kuya kolunye, amehlo akho asesekuqondeni, akunjalo? Awugxumi lapho ugijima. Lokho kungenxa yalokhu kuguquguquka okubizwa ngokuthi i-VOR . Okusho ukuthi, amehlo akho ahamba ngendlela ephambene nokunyakaza kwekhanda lakho ukuze agcine amehlo akho eqinile. Ngaphandle kwalokhu, ungazizwa unesizungu futhi uwe kalula.

• I-Vestibulospinal reflex (VS reflex): Imisipha yakho iyazivumelanisa ngokuzenzakalelayo nezinguquko ohlelweni lwakho lwe-vestibular. Cabanga uhamba emgwaqweni ongalingani, onamatshe. Njengoba ikhanda lakho lihamba kancane, uhlelo lwakho lwe-vestibular lubona ushintsho endleleni yakho yokuma. Ngaleso sikhathi, i -VS reflex ishintsha isisindo somzimba wakho ukuze ibuyisele emuva, ikuvimbele ekukhubekeni.

Lukuphi lolu hlelo lwe-vestibular?

Izitho zomzimba zesistimu yakho ye-vestibular zitholakala endlebeni yakho yangaphakathi . Indlebe yakho yangaphakathi nayo iyikhaya le-cochlea, ekusiza ukuzwa. Kukhona enye ingxenye yendlebe yangaphakathi ebizwa ngokuthi i-vestibular labyrinth . Ngaphakathi kulapho kutholakala khona izitho zakho ezinhlanu ze-vestibular (ezibizwa nangokuthi "i-vestibular apparatus").

Lezi zitho zomzimba zibona indawo yekhanda lakho bese zithumela izimpawu ezingxenyeni zobuchopho ezikusiza ukuthi ugcine ibhalansi.

Yiziphi izingxenye zesistimu ye-vestibular?

Kunezitho ezinhlanu eziyinhloko ze-vestibular ngaphakathi kwedivayisi ye-vestibular endlebeni yakho yangaphakathi:

• Imisele emithathu eyindilinga
• Izitho ezimbili ze-otolith

Idivayisi ye-vestibular, equkethe lezi zitho zomzimba, igcwele uketshezi olubizwa ngokuthi i-endolymph kanye namaseli amancane enzwa afana nezinwele abizwa ngokuthi ama-hair cell sensory receptors. Uma ikhanda lakho lihamba, le-endolymph iyahamba iye emuva naphambili. Amaseli ezinwele abe esehamba nayo. Ngenxa yalokhu kunyakaza, amaseli athumela ulwazi lwenzwa mayelana nokunyakaza kwakho ebuchosheni. Lezi zimpawu zemizwa zihamba nge-nerve ebalulekile ebizwa ngokuthi i-vestibular nerve (ebizwa nangokuthi i-vestibulocochlear nerve noma i-8th cranial nerve).

Imisele eyisiyingi

Lawa amapayipi amathathu endlebeni yakho yangaphakathi aqaphela ukunyakaza kwekhanda okujikelezayo.

• Umsele ophakeme:Bayaqaphela ukunyakaza kwekhanda (njengokunqekuzisa ikhanda ukuze bathi "yebo").
• Umsele ovundlile: Ibona ukunyakaza kwekhanda kusuka kwesobunxele kuya kwesokudla (njengokunikina ikhanda lakho ukuze uthi "cha").
• Umsele wangemuva: Ubona ukunyakaza okugoba ikhanda kusukela kolunye uhlangothi kuya kolunye (njengokutshekisa ikhanda liye ohlangothini).

Umsele ngamunye uphela ngesakhiwo esibizwa ngokuthi i-ampulla . Ngaphakathi kwale ampulla kunamaseli ezinwele, asatshalaliswe njengento efana nejeli ebizwa ngokuthi i-cupula . Uma uhambisa ikhanda lakho, uketshezi lwe-endolymph ngaphakathi kwemisele eyindilinga luhamba luye emuva naphambili. Amaseli ezinwele ngaphakathi kwe-cupula ahamba nalo. Lokhu kunyakaza kuthumela izimpawu zemizwa ebuchosheni, kubutshele ukuthi ikhanda lakho likuphi.

Izitho ze-Otolith

Lawa ngamakamelo amabili athola ukunyakaza okuqondile okuhlobene namandla adonsela phansi.

• I-Utricle: Ithola ukunyakaza okuvundlile (phambili noma emuva, njengalapho ugibele imoto).
• I-Saccule: Ibona ukunyakaza okuqondile (phezulu noma phansi, njengalapho ugibela ilifti).

Isitho ngasinye se-otolith sinesakhiwo esibizwa ngokuthi i-macula . Le macula iqukethe namaseli ezinwele. Afakwe entweni efana nejeli ebizwa ngokuthi i-otoconia, egcwele amakristalu e-calcium. Uma uhamba, lawa ma-otoconia ngaphakathi kwezitho ze-otolith ahamba phambili naphambili. Amaseli ezinwele abe esehamba nawo. Lokhu kuhamba kuthumela izimpawu zemizwa ebuchosheni.

Yiziphi izifo ezithinta uhlelo lwe-vestibular?

Ngeshwa, ngisho nalesi simiso esihle ngezinye izikhathi singaba nezinkinga. Yilapho izinto ezifana nesiyezi kanye nokuquleka zingase zenzeke khona. Kunezindawo ezimbili eziyinhloko lapho izinkinga zingase zenzeke khona:

Izifo ezivame kakhulu ze-peripheral (indlebe yangaphakathi) ze-vestibular yilezi:

• I-Benign Paroxysmal Positional Vertigo (BPPV) : Yilapho amabhola amancane abizwa ngokuthi i-otoconia ngezinye izikhathi ethuthela emiseleni. Lokhu kubangela isiyezi esikhulu uma ushukumisa ikhanda lakho.
• I-Labyrinthitis : Ukutheleleka noma ukuvuvukala kwedivayisi ye-vestibular yendlebe yangaphakathi.
• Isifo sikaMénière : Isimo esibangelwa ukwanda komfutho woketshezi endlebeni yangaphakathi. Izimpawu zingase zihlanganise ukulahlekelwa ukuzwa, ukukhala ezindlebeni, kanye nesiyezi.
• I-Vestibular neuritis: Ukuvuvukala kwe-vestibular nerve.

Izifo ezivame kakhulu ze-vestibular eziphakathi yilezi:

• I-Mal de débarquement syndrome (MdDS) : Ukuzizwa sengathi usathuthumela ngemva kokwehla emkhunjini noma esikebheni.
• Isiyezi Esiqhubekayo Sokubona Isimo Sengqondo (PPPD): Isiyezi esiqhubekayo okunzima ukuthola imbangela yaso.
• I-Vestibular migraines: Isiyezi esihambisana ne-migraines.

Wazi kanjani ukuthi kunenkinga ngesistimu ye-vestibular? Ziyini izimpawu?

Izimpawu eziyinhloko zezinkinga zokulinganisela yisiyezi kanye ne-vertigo . Zombili lezi zinto zingabangela ukungakhululeki kanye nobunzima bokuma, kodwa zihlukile kancane.

Uma unesiyezi, ungase uzizwe:

• Woozy
• Unekhanda elikhanyayo, uzizwa unekhanda elikhanyayo
• Ukuzizwa udidekile, ungakwazi ukuqonda ukuthi ukuphi (Udidekile)

Uma une-"vertigo" (isiyezi/ukujikeleza okukhulu), ungase uzizwe:

• Kuzwakala sengathi uyajikeleza yize umile nje.
• Ukuzizwa sengathi umhlaba wonke uyajikeleza nxazonke zakho.

Abanye abantu bathi, "Ngizizwa nginesizungu." Kungaba isizungu, noma kungaba isizungu. Uma unesizungu, uvame ukuzizwa sengathi wena noma indawo okuzungezile iyajikeleza. Kufana nokuthi usethoyizini elijikelezayo.

Kanye nalezi zimpawu, kuye ngesimo esithile se-vestibular onaso, ungase ubhekane nezinye izimpawu ezithinta ukuzwa kwakho kanye nokubona. Ngenxa yokuthi uhlelo lwakho lwe-vestibular luxhumene eduze namehlo nezindlebe zakho (izitho eziyinhloko zokuqonda nazo zisendlebeni yangaphakathi), lezi zinkinga ngezinye izikhathi zingahlangana.

Ungayihlola kanjani impilo yesistimu ye-vestibular?

Indlela eyinhloko odokotela abaxilonga ngayo izimo ze-vestibular iwukuhlola i-vestibular . Lokhu kuhilela ukwenza izivivinyo eziningana ukuhlola impilo yesistimu yakho ye-vestibular. Izivivinyo eziningi zibheka ukuthi amehlo akho kanye nesistimu ye-vestibular zisebenza kahle kangakanani ndawonye ukuze kugcinwe ibhalansi (yileyo VOR esikhulume ngayo ngaphambili).

Kungadingeka futhi ukuthi uhlolwe igazi ukuze uhlole izifo, noma ukuhlolwa kwezithombe (isib., i-MRI scan) ukuze uhlole izinkinga zesakhiwo ezithinta uhlelo lwakho lwe-vestibular.

Yiziphi izindlela zokwelapha izimo zesistimu ye-vestibular?

Izimo eziningi ze-vestibular zidinga inhlanganisela yokwelashwa, okusho izindlela zokwelapha ezingaphezu kweyodwa.

• Izinguquko endleleni yokuphila: Ukunciphisa izinto ezifana nokucindezeleka okubangela isiyezi.
• Ukwelashwa ngokomzimba kwe-Vestibular: Lokhu kungasiza ekunciphiseni izimpawu, kuqinise izakhiwo ezibuthakathaka njenge-VOR, noma kwenziwe izindlela ezithile zokushintsha indawo yezimo ezifana ne-BPPV.
• Imithi: Imithi inganikezwa ukwelapha ukutheleleka noma ukunciphisa izimpawu zesiyezi, njengesicanucanu.
• Ukuhlinzwa:Ngezinye izikhathi, kungase kudingeke ukuhlinzwa ukuze kulungiswe izakhiwo ezisendlebeni yangaphakathi ezibangela inkinga. Kodwa-ke, lokhu kuvame ukuba yindlela yokugcina.

Sigcina kanjani lesi simiso se-vestibular siphilile?

Eqinisweni, izinkinga eziningi ze-vestibular kunzima ukuzivimbela. Kodwa-ke, unganakekela uhlelo lwakho lwe-vestibular (kanye nawe) ngokufuna ukwelashwa ngokushesha ngangokunokwenzeka lapho kuvela izimpawu zokuqala zenkinga.

Isibonelo, ezinye izimo, njengokutheleleka kwendlebe yangaphakathi, zingaphola ngokuhamba kwesikhathi, kodwa zingalimaza amangqamuzana ezinwele azwelayo ngaphakathi kwendlebe yakho. Uma lawa maseli onakele, awakwazi ukukhula futhi. Yingakho kubalulekile ukuthola ukwelashwa ngokushesha.

"Ulinganisela" kanjani uhlelo lwe-vestibular?

Ukwelashwa kokuvuselelwa kwe-Vestibular kuyindlela yokwelapha ekusiza ukuthi uhlele kangcono izingxenye zesistimu yakho ye-vestibular. Ngokusebenza nodokotela noma uchwepheshe wezokwelapha ngokomzimba ogxile ezinkingeni ze-vestibular, ubuchopho bakho bungaqeqeshwa ukuthi buphendule kahle imiyalezo evela ezithweni ze-vestibular ezisendlebeni yakho yangaphakathi. Lokhu kusho ukuthi ubuchopho bakho bungazivumelanisa futhi busebenze ngokujwayelekile ngisho noma kunenkinga ngesistimu.

Okokugcina, okufanele ukukhumbule (Umyalezo Wokuya Ekhaya)

Uma uzwa igama elithi "vestibular," kufika elinye igama elilula engqondweni: ibhalansi . Njengomuzwa wakho wokunambitha, ukuthinta, ukubona, ukuzwa, nokuhogela, umuzwa wakho wokulinganisela ubaluleke ngendlela efanayo. Akwaziwa kangako, kodwa kubalulekile. Izitho ze-vestibular endlebeni yakho yangaphakathi zenza umsebenzi omuhle wokukugcina uqonde futhi ungawi.

Ngakho-ke, uma unezimpawu zenkinga ye-vestibular, njengesiyezi, ikhanda elikhanyayo, noma i-vertigo, ungamane uyishaye indiva bese ubona udokotela ngokushesha . Ngaleyo ndlela, uhlelo lwakho lwe-vestibular lungaphathwa kahle.

Khumbula, lolu lwazi lungolwakho kuphela. Uma unenkinga yezempilo, sicela ucele iseluleko kuchwepheshe wezokwelapha ofanelekayo.
