Human analyzer vestibular. Sakhiwo umsebenzi

I analyzer vestibular wuhlelo izakhiwo kwemizwa kanye mechanoreceptors, okuvumela umuntu azibonayo kahle Orient isikhundla umzimba wakhe isikhala. Mechanoreceptors ezishukumisa kukhona ehlukile ukushesha. accelerations Angular kubangele excitation receptor ampullar. Imvelo rectilinear ikhuthaza ukushesha izinzwa ishayela nesenzakalo egumeni. Vestibular kanye pulses ampullar aguqulwa ibe amaza nerve futhi usize ukugcina uhlelo sezinzwa, orientation in space.

Isakhiwo analyzer womuntu vestibular

ikhaliphe Static ziyafezeka ngokusebenzisa ukuxhumana zemizimba uyakwazi ukubona ukuthi iyini ezishukumisa futhi uguqule wabayisa emsipheni amaza. Amasignali ivela apharathasi vestibular emsipheni vestibular, lapho zingena ezindaweni we oblongata medulla. Ngobusuku obandulela amthanda yami ibekwe esikhwameni. zabo surface embozwe amaseli sezinzwa okuyinto zihlukaniswe ifomu columnar kanye eliphakathi kwe. izinwele ezizwelayo kula maseli sizungezwe ulwelwesi otolith. Lapho ukuhamba ikhanda amandla adonsela phansi we otoliths shift futhi kuthinte izinwele sezinzwa. Ukuze ingxenye basal we inzwa cell exhunywe-kwalapho ukuthi amasignali kusukela izinwele.

imisebenzi eyisisekelo

Ukutadisha analyzer vestibular wembula izinhlobo ezinhlanu ukusabela lapho kukhiqizwa:

1. Vestibulosomaticheskie ukusabela okubangelwa vestibulo izibopho. Ngosizo lwabo, analyzer vestibular ikhuthaza ukuhanjiswa imisipha ithoni at accelerations ezahlukene.
2. Oculomotor ukuphendula. Basuke kubangelwa khona amehlo motor ukuxhumana futhi abangele ukunyakaza okungalindelekile kwamehlo noma i-nystagmus. Le nqubo biphasic. Esigabeni sokuqala le ukucasuka yokwamukela ampullar futhi okwalandela ukunyakaza kancane maqondana iso. Esigabeni sesibili okuholela okusheshayo ezinyakazayo uhlawula zamehlo ubuyele esikhundleni sazo sokuqala. analyzer Vestibular kuphakamisa nystagmus zokuthola qeda imvelo izingcezwana ngesikhathi ukunyakaza ukujikeleza. Iphinde kusiza umuntu Yibhaleni of izinto ukuthi lihamba ngesivinini.
3. imisebenzi Vestibular nezimo uhlamvu. Uma unanoma yimiphi yale ukusabela kungenzeka palpitations, kukhuphuke blood pressure, kubangele isicanucanu on isizinda kuyashesha senzo.
4. Vestibulomozzhechkovye ukusabela zenzeka ngesikhathi ukunyakaza asebenzayo. Isiza ukulawula isikhundla umzimba emkhathini, lapho umzimba usesimweni ashukumisayo. Lokhu kufezwa ngokushintsha ukusatshalaliswa efanele kwemisipha ithoni at accelerations ezahlukene.
5. Ngenxa ukuxhumana ne vestibular cortex analyzer kusiza ukuqaliswa kwe-central ukuqapha kanye nokulungisa vestibulosensornoy ukuphendula.
