Chii nhengo Corti?

Vakawanda vanofarira nhengo Corti yayo mabasa. Iva Kanenge munhu succinct pfungwa kune vose. Corti kuti nhego anonzi peripheral chikamu kunzwa rubatsiro. Riri mune membranous labyrinth. Nokufamba shanduka pahwaro ari lateral mutsetse (kureva, zvivako zvavo) uye vakava chikamu ichi acoustic analyzer.

Iye otora vibration mafungu dziri labyrinth womukati nzeve, uye ipapo anotuma navo auditory chikamu chepfungwa cortex, zvokuti pane omumwe inzwi. The nhengo Corti ane chinokosha basa. Ndiyo apo pakutanga inotungamirwa kuongorora akaita siyana zvakarekodhwa anonongedzera. muviri ichi pakutanga yakawanikwa Alfonso Corti - Italian histologist.

Aripiko nhengo Corti?

Riri mune cochlear kosi umo perilymph uye endolymph, uye inomiririra mhou labyrinth, zvakafanana zononoka. Yokumusoro Chikamu achimhanya yakabatana anonzi vestibular manera. Inonzi Reissner kuti membrane. A repasi chikamu, iri pedyo Scala tympani, rine chikuru Kamudzira neVadzidzi osseous zononoka lamina.

Purpose uye Structure

The nhengo Corti iri huru Kamudzira, zviri inoumbwa wokunze uye yomukati bvudzi masero uye rutsigiro. Somuenzaniso, danda-kutungamirira. Kunosanganisirawo Hensen masero uye Deiters Claudius. Of kwavari ndiyo nhengo Corti. Pakati pavo mugero kuburikidza iyo anomunzwira axons ari etsinga kuva zononoka raiva pedyo nebundu. Dzinobhururuka kuti kuteerera inzwi anonongedzera vhudzi masero. Ekupedzisira, akavapindurawo, vavete pamigumo yamativi akasika nokutsigira musero miviri. On dzavo pamusoro akatendeukira kurutivi pabutiro Kamudzira hwakarongwa kubva 30 kusvika 60 hupfupi bvudzi. Kutsigira masero anoitwa sezvo trophic ushande. How chaizvo? Vakatuma bvudzi masero nezvinovaka muviri. Basa reDare Corti - Kushandurwa ruzha vibrations kupinda tsinga excitation simba. Kuti aite izvi, chokwadi, zvaanoshaiwa. Ndizvo mashandiro ari nhengo Corti. Histology anobvumira kuzivana pamwe ayo mamiriro.

physiology

The eardrum otora ruzha vibrations izvo kuburikidza mapfupa iri pakati nzeve, vanowira nemvura svikiro - endolymph uye perilymph. kufamba yavo inobatsira kuti chokwadi kuti chifukidziro Kamudzira ari nhengo Corti dzikaruma kubviswa bvudzi mumasero. Chii chinoitika somugumisiro? First hwakakungwa bvudzi. Ipapo biopotentials kuti anonzwisiswa zononoka ganglion (kana panzvimbo, neuronal ake pezvakaitwa). Vanosvika pasi bvudzi masero ose. The nemamiriro nhengo Corti inofarirwa kwazvo nevaongorori vakawanda.

Another dzidziso

Panewo maonero akasiyana panyaya iyi. Sezvazvakanyorwamo, bvudzi masero catcher beeps - chete antennas inoshanda kuti depolarized nokuda kuona kusvika nemafungu. A rinokosha iri kuridzwa pano nokuda endolymphatic acetylcholine. Depolarization zvinokonzera kutevedzana kwemakemikari transformations vari bvudzi mumasero, dzinoti zviri cytoplasm yavo. Zvadaro, vaaisangana navo harinzwi tsinga ngapaonekwe kusagadzikana zvatinganzwa. At ruzha vibrations zvinogona zvakasiyana kukwirira. Nokuti mumwe nomumwe wavo ndizvo yoga chikamu nhengo Corti. High Frequency vibration kutsamwisa migove cochlear raiva pedyo pasi, uye pasi - pamusoro. Izvi imhaka hydrodynamic mananara ari cochlea. The nhengo Corti, mashandiro anoita yauri zvino anozivikanwa kuridza ichi yose muitiro basa rinokosha.

Zvakaratidza kuti nedhambakura inogona aionekwa zvokuimba determinant pamusoro Frequency akapindura: kwayo chiito, afanane zita rake. Asi pamusoro maikorofoni hazvina kufanana chaizvo.

Nei izvi zvichikosha?

Nokuda pamusoro features, uropi anogona pakarepo sei nemitinhimira uye kwete kuita ari Fourier rokuchinja, pasina rubatsiro wemasvomhu (panzira, nokuti iye haana kadambari simba) kugadzirisa zviri ratorwa, mashoko matsime. Zvaiva kuoma. Zviri nyore kunzwisisa chii nhengo Corti, pane kufungidzira muitiro wakadaro.

How kuwana mashoko aunoda?

Kuti uzive zvakawanda pamusoro chisina kutsetseka inoenda chiratidzo bhuku, zvakakodzera kuteerera polarization nokurira harmonics. Izvi zvinokosha ezvinhu. Zvakaratidza kuti nzeve runoita kuti vatore ruzivo pamusoro polarization. Unogonawo kudzidza pamusoro amplitude ari harmonic ruzha. Kana yakaderera frequencies uropi nenzeve, pakati pezvimwe zvinhu, vanogamuchira mashoko pamusoro maitikiro ari harmonics, uye naizvozvo, anogona kurondwa kutungamirirwa vibration. Chii chandichiri kushayiwa? Just ngaaverenge musiyano pakati maitikiro inzwi kubva kuruboshwe uye yorudyi. Zviri nyore zvakakwana, handizvo here? Kunyange, zviri nyore kunzwisisa chokwadi kuti isangano reDare Corti.

Feature mamwe compression dzemakaseti okuteerera mashoko anogona kuderedza nguva kuti kuongorora mashoko akanga agamuchira. Snail ari vakamonyanisa, uye nokudaro zvinokwanisika kubvisa chakarondedzera panguva iyoyowo mubatanidzwa pasi.

Zvino munoziva kuti ndiyo nhengo Corti uye sei muronga. Sezvaunoziva nayo anoita mabasa. Zvose izvi zvakakosha zvikuru uye zvinobatsira kuziva.
