Human vestibular analyzer. Mamiriro uye basa

The vestibular analyzer ndiyo kwegadziriro Neural zvivako uye mechanoreceptors, izvo anobvumira munhu kunzwisisa uye zvakarurama dzokumabvazuva nzvimbo muviri wake muchadenga. Mechanoreceptors mikana yakawanda yokukurudzira dzakasiyana pamusoro kumhanyisa mhando. Chisina kutsetseka accelerations vanokonzera excitation ampullar receptors. The rectilinear hunhu rinokurudzira kumhanyisa sensors kupomba kuwanikwa muna kumusuwo. Vestibular uye ampullar pulses vari dzikwanise tsinga anonongedzera uye kubatsira kuchengeta musimboti tsinga, dzidziso iri muchadenga.

Sechivako vestibular dzevanhu analyzer

Kunofambira mberi hunenge vari vakaziva kuburikidza nesungano kwemiviri vanokwanisa kunzwisisa mikana yakawanda yokukurudzira oshandura vave tsinga nomunhu. Anonongedzera achibva vestibular midziyo kune vestibular etsinga, kuburikidza iyo vachipinda munzvimbo yacho medulla oblongata. Pausiku Mudikanwi wangu uye akaisa bhegi. dzavo pamusoro wakafukidzwa masero kutsinga dzinouya ayo rakakamurwa columnar chimiro uye peya. Nzwisisa bvudzi masero aya dzakapoteredzwa otolith membrane. Apo kufamba musoro nesimba regiravhiti pamusoro otoliths dzinofamba uye kukanganisa kutsinga dzinouya bvudzi. Kuna basal chikamu Switch sero kwakabatana-tsinga harinzwi vanogamuchira anonongedzera kubva vhudzi.

zvinhu mabasa

Kudzidza vestibular analyzer kwakaratidza mhando shanu wanda dzavakange anobudiswa:

1. Vestibulosomaticheskie Maitiro akaita vestibulo zvisungo. Uchibatsirwa wavo, vestibular analyzer inosimudzira redistribution kuti tsandanyama matauriro panguva accelerations siyana.
2. Oculomotor kuita. Vari anokonzerwa kuvapo ziso-injini kubatana uye kukonzera involuntary kufamba kwemaziso kana nystagmus. Izvi ndizvo biphasic. In wokutanga chokutambudzika iri kutsamwa ampullar Kanotokonya kwaizotevera kunonoka kufamba kurutivi ziso. In yechipiri Pasika zvichiguma nokukurumidza zvitange compensating eyeballs kudzoka chepakutanga nzvimbo. Vestibular analyzer chinokurwadzai nystagmus kuti kugadzira chiutsi ezvinhu zvimedu panguva yacho rotational kufamba. Chinobatsira munhu arambe zvinhu zviri kutamira panguva kumhanya.
3. Vestibular mabasa vari nezviripo hunhu. Kana uine chinhu wanda izvi anogona palpitations, wakawedzera BP, kukonzera svoto pamusoro yaitwa kuwedzera chiito.
4. Vestibulomozzhechkovye Maitiro munguva kushingaira kufamba. Dzinoita kuti pave kudzora muviri nzvimbo muchadenga, kana muviri vari simba ezvinhu. Izvi zvinoitwa zvakakodzera kugovera tsandanyama matauriro panguva accelerations siyana.
5. Nemhaka kubatana pamwe vestibular cortex analyzer kunobatsira Implementation ari nechepakati zvichiongororwa uye kururamiswa vestibulosensornoy kuita.
