Ezingaphakathi endlebeni. Sakhiwo umsebenzi.

Indlebe ubhekwa nzima isitho vestibular ukuthi unesibopho sokwenza imisebenzi emibili. It uyabubona amaza omsindo, unesibopho ekulondolozeni ukulinganisela futhi unekhono ubambe umzimba emkhathini endaweni ethile. Indlebe - isitho abhanqiwe, ise ithambo temporal of kogebhezi kunomkhawulo auricles ngaphandle. Indlebe imelelwa neminyango emithathu, ngamunye okuyinto unomthwalo imisebenzi ethile: elingaphandle, maphakathi kanye kwangaphakathi.

Ezingaphakathi endlebeni. Ukwakheka.

I Sakhiwo sangekhatsi ezindlebeni kancane like Umnenke (yingakho inegama elifanayo), futhi kwakha isimiso esiyinkimbinkimbi ijabulise, okuyinto ugcwele ketshezi. Zengaphakathi lendlebe Itholakala wethambo yesikhashana ukujula, yakhiwa izingxenye ezimbili - i-cochlea (isitho sokuzwa) futhi le misele ongaphambili omise (yakhoibrium isitho).

Lemigwamanda zimumethe apharathasi zvukovosprinimayuschego futhi analyzer vestibular, okuyinto unomthwalo isikhundla umzimba emkhathini, ukuze kugcinwe yakhoibrium, kanye imisipha ithoni. commonality yokwakheka lwalezi nhlelo ezimbili ezibalulekile kubaluleke kakhulu, futhi ukungalingani yabo kungabangela hhayi kuphela izinkinga kokuzwa, kodwa futhi umsebenzi ngalesi sifo vestibular, isici esiyinhloko okuyinto ukuhlanza, isicanucanu, isiyezi.

indlebe Inner ibhalansi isitho

I-apharathasi vestibular noma uhlaka yakhoibrium yakhiwa imiselekazi ongaphambili omise, okuyinto ahlelwe izindiza ezintathu perpendicular futhi sacs ezimbili ezincane. Perilymph ukugcwalisa iziteshi, ngaphakathi okuyinto kunezinye emiseleni egcwele endolymph, bekhulumisana imisinga yamanzi cochlea. Ukudideka kwalapho ifomu pulses ukuthi aphendule ukuthambekela ikhanda, ubuchopho sinquma indlela umzimba ibekwe maqondana ikhanda.

Kunezimo lapho amaseli vestibular yakha pulses ngezizathu ngempela ehlukile kunaleyo ikhanda iphendula. Leso simo kungenzeka ukuvuvukala endlebeni engaphakathi, noma ngezinye pathologies, isibonelo, uma obuphumela meatus sokuzwa kuyinto amanzi ashisayo noma okubandayo kakhulu. Ezimweni ezinjalo, kungase kube lokujabulela isicanucanu nesiyezi, kuze kube ukulahlekelwa orientation emkhathini.

uhlaka ukuzwa

Zengaphakathi lendlebe unesibopho kokuzwa emizweni. amaza omsindo ngokusebenzisa ifasitela okusaqanda endlebeni engaphakathi ngibangele ezinyakazayo uketshezi nokudludliza ka villi amancane. Villi ukuguqula kunyakaza sibe amaza ukuthi emsipheni sokuzwa ngokufaka ubuchopho, nobuchopho uye kamuva uqhuba ukuguqulwa zabo zibe izithombe sokuzwa.

Zengaphakathi lendlebe unesibopho ukuvama ukuthola, sibonga ngalo umuntu unekhono ukuhlukanisa umsindo eyodwa ukusuka kwenye. uchungechunge Complex of izinqubo electromechanical of endlebeni isebenzisa zonke izingxenye zawo, ukuze ukuzwa kwaba ngokulandelana kumele wonke umsebenzi kahle bona. Uma okungenani eminye yale izindlela sehluleke, nabangezwa kahle.

Ukuzwa ukulahleka - the angahlangani evamile endlebeni

Umsindo endlebeni libhekene izici ezifana amplitude futhi imvamisa. Amplitude - lena amandla ngalo umsindo wegagasi ucindezela ulwelwesi, imvamisa, esikhundleni salokho, inquma inani sonic wave oscillation, okuyinto lenzani endaweni yesibili. Ukulahlekelwa ikhono lokuhlukanisa phakathi imisindo ukuthola amaza ethile okuthiwa ukulahlekelwa ukuzwa. Ukuzwa Kungase kube ukulahlekelwa conductive, sensorineural futhi edidayo. Sensorineural ubuthulu kungukuphula nozwela cochlea noma sokuzwa emsipheni umsebenzi ukwehla. Conductive ubuthulu - kuphula umthetho we conduction phakathi yangaphandle futhi maphakathi nendlebe, luhlanganiswe ubuthulu limelela labo nezinye izifo.
