The nzeve yomukati. Marongerwo uye ushande.

The nzeve anoonekwa kutiomera vestibular nhengo kuti basa nokuita mabasa maviri. It Anoona ruzha, riri basa tiine mwero uye anokwanisa abate muviri muchadenga mune imwe nzvimbo. Nzeve - a aiwanzopiwa wokushanda nhengo, riri zvenyama bvupa Nemadehenya uye kungogumira kunze auricles. The nzeve chinomiririrwa madhipatimendi matatu, rimwe nerimwe riri basa mamwe mabasa: wokunze, pakati uye rwomukati.

The nzeve yomukati. Mamiriro.

The womukati nemamiriro nzeve zvishoma rakaita nedhambakura (chiri sei ine zita iroro), uye ari kunzwisisa tubular gadziriro, iyo wakazara mvura. The nzeve chomukati iri mu kudzika zvenyama pfupa, izvozvo rinoumbwa zvikamu zviviri - the cochlea (the auditory nhengo) uye semicircular migero (zvakanyatsoenzana nhego).

mitumbi izvi vanoumba kuti zvukovosprinimayuschego midziyo uye vestibular analyzer, riri basa muviri nezvenzvimbo muchadenga, nokuti kwerunyararo zvakanyatsoenzana, uyewo tsandanyama matauriro. Anatomical commonality izvi zviviri hurongwa anokosha kunokosha chaizvo, uye kusaenzana kwavo kunogona kukonzera kwete chete nezvinetso kunzwa, asiwo kushanda vestibular chirwere chikuru chinoratidza inova kurutsa, kuda kurutsa, dzungu.

Munzeve nepakati nhego

The vestibular midziyo kana nhengo zvakanyatsoenzana rinoumbwa ari semicircular yaNire, izvo akarongwa matatu perpendicular ndege, uye SACS mbiri duku. Perilymph achizadza migero, mukati umo pane dzimwe migero vakazadzwa endolymph, vachikurukura hova pasi cochlea. Kutsinga dzinouya tsinga harinzwi chimiro pulses kuti sei kwakarerekera musoro, uropi anoti sei muviri papi chokuita musoro.

Pane mamiriro ezvinhu apo vestibular masero anoumba pulses nokuti zvakasiyana zvikonzero kupfuura musoro kwaanoda. mamiriro ezvinhu akadaro kunogona kuitika munguva kuzvimba womukati nzeve, kana mune dzimwe pathologies Somuenzaniso, apo akasunungura kupinda auditory meatus iri inopisa kana akanyanya kutonhora mvura. Muzviitiko zvakadaro, zvingava kutekenyedzwa kuti kuda kurutsa uye dzungu, kusvikira kurasikirwa zvevhiki muchadenga.

nhego rokunzwikwa

Yomukati nzeve ndiyo anokonzera kunzwa nezvekufadza. Sound mafungu kuburikidza denderedzwa hwindo dzomukatikati nzeve uye kuti Urume inofamba uye vibrations duku villi. Villi exchange vibrations kupinda nomunhu kuti auditory etsinga kupinda uropi, uye uropi rave vakazoroorwa anoitisa Kushandurwa yavo auditory mifananidzo.

Yomukati nzeve ndiyo anokonzera kakawanda kuonekwa, nemhaka iyo munhu anokwanisa kusiyanisa mumwe inzwi kubva neimwe. Complex ngetani electromechanical dzinotsanagura munzeve rinoshandisa nhengo dzayo dzose, saka kuti kunzwa waiva kuti vanofanira zvose basa zvakanaka. Kana pane dzimwe nzira idzi haangashaikwi, kunzwa vasingadzoreki.

Kunzwa kurasikirwa - vakawanda abnormality womukati nzeve

The varurame nzeve dzinoratidzwa zvinhu zvakadai amplitude uye maitikiro. Amplitude - ndiwo simba izvo kurira chinozunguzirwa unomanikidza Kamudzira, kakawanda, uyewo, kuwanda sonic chinozunguzirwa oscillation, izvo zvine kechipiri. Kurasikirwa mano okusiyanisa mitinhimira uye kuziva zvimwe frequencies inonzi kusanzwa. Kunzwa kurasikirwa angava conductive, sensorineural uye zvakasiyana. Sensorineural kusanzwa ari kutyora nehanya of cochlea kana auditory tsinga kushanda kuderera. Conductive kusanzwa - kutyorwa conduction pakati wokunze uye pakati nzeve, uye zvakavhenganiswa kusanzwa chinomirira avo uye zvimwe zvirwere.
