Uyini uhlaka Corti?

Abaningi banesithakazelo uhlaka Corti kanye nokwenza imisebenzi yayo. Yiba okungenani umqondo lesifinyetiwe kuba kuwo wonke umuntu. isitho Corti ibizwa ngokuthi ingxenye neuropathy we izinsizakuzwa. Itholakala ku uxhaxha membranous. Ngokuhamba kwemvelo ngesisekelo lateral line (okungukuthi, izakhiwo zabo) futhi ithuthukiswe le ngxenye analyzer acoustic.

Yena ucosha amagagasi vibration ezisesandleni uxhaxha of endlebeni engaphakathi, bese ithumela ukuba ingxenye sokuzwa we- cortex cerebral, futhi umphumela waba ukuthi kukhona bezibona umsindo. Uhlaka Corti inomsebenzi omkhulu. Lapha kulapho kokuqala kumiswa yokuhlaziya okwenziwe izinhlobo amasignali umsindo. Lokhu umzimba eyaqala ukutholwa Alfonso Corti - histologist Italy.

Likuphi uhlaka Corti?

Itholakala inkambo cochlear lapho perilymph futhi endolymph, futhi imelele uxhaxha bony, efana a Kuvunguza. Ingxenye engenhla egijima eseduze okuthiwa ezitebhisini vestibular. Ibizwa ngokuthi ulwelwesi Reissner sika. Ingxenye engezansi, etholakala eduze tympani Scala, siqukethe ulwelwesi main nabo osseous lamina Kuvunguza.

Inhloso Sakhiwo

Uhlaka Corti isendaweni ulwelwesi main, walibumba is yi yangaphandle futhi kwangaphakathi zengaphakathi nokusekelwa. Njengoba isibonelo, pole phambili. Lihlanganisa Hensen amaseli bese Deiters uKlawudiyu. Wabo futhi uhlaka Corti. Phakathi kwabo kuyinto Umhubhe lapho ukunweba axons e emsipheni kokuba Kuvunguza engeyokuqala. They sukela ephendula amasignali umsindo amaseli izinwele. Lesi sakamuva, esikhundleni salokho, amanga kude wadala ngokusekela emizimbeni cell. Surface babo bubheke maqondana ikhava ulwelwesi luyatholakala kusuka 30 kuya ku-60 izinwele kunalokho iDemo. Ukusekela amaseli kwenziwe njengoba umsebenzi trophic. Kanjani ncamashi? Bathumela kuya zengaphakathi izakhamzimba. Indima uhlaka Corti - ukuguqulwa of kunyakaza umsindo nezinzwa excitation amandla. Ukuze wenze lokhu, eqinisweni, lokho akudingayo. Yilokho umsebenzi uhlaka Corti. Histology ivumela sokumazi futhi nge oyiyo.

izitho zomzimba

I eardrum ucosha kunyakaza umsindo okuyinto ngokusebenzisa amathambo etholakala maphakathi nendlebe, awela medium liquid - endolymph futhi perilymph. ukunyakaza yabo neqhaza yokuthi ulwelwesi isifulelo uhlaka Corti kancane asuswe amaseli izinwele. Kwenzekani ngenxa yalokho? izinwele Okokuqala insaliwe. Bese kuba khona biopotentials ukuthi ziqondakala ganglion Kuvunguza (noma kunalokho, izinqubo zakhe neuronal). Eza phansi wonke amaseli izinwele. Isakhiwo uhlaka Corti Sinesithakazelo esikhulu ukuba abacwaningi abaningi.

Omunye umbono

Kukhona umbono ezahlukene ngale ndaba. Ngokusho ke, amaseli izinwele umzingeli imisindo - kuphela antenna ebucayi ukuthi depolarized ngu ukuchayeka ukufika amagagasi. A indima ebalulekile udlalwa lapha yi acetylcholine endolymphatic. Depolarization kubangela ukulandelana kugucuka kwamakhemikhali emangqamuzaneni izinwele, okungukuthi cytoplasm yabo. Ngemva kwalokho, abaxhumana nabo eziyimpumelelo ezinzwa avele ngiyibona sezinzwa. Lapho kuzwakala umsindo kunyakaza kungaba ukuphakama ezahlukene. Ukuze ngamunye wabo kuyingxenye ehlukile uhlaka Corti. High imvamisa vibration ukuze kuvuswe izingxenye cochlear elise eduze phansi, kanye ongaphakeme - phezulu. Lokhu kungenxa imihlola hydrodynamic ku cochlea. Uhlaka Corti, imisebenzi zazo wena manje eyaziwa ukudlala lonke le nqubo indima ephawulekayo.

It kuvela ukuthi Umnenke kungenziwa ithathwa njengendlela determinant mechanical imvamisa impendulo: wesenzo, kufana igama lakhe. Kodwa ku-microphone akusiyo ayefana kakhulu.

Kungani le nqubo kubaluleke kangaka?

Ngenxa izici ezingenhla, ubuchopho ngokushesha aphendule imisindo ethile, kunokuba uphishekele a Fourier uguqule, ngaphandle kosizo wezibalo (endleleni, ngoba ingenakho amandla ama) ukuhlunga athunjwa, imithombo ulwazi. Kungaba nzima kakhulu. Kulula ukuqonda ukuthi yini uhlaka Corti, kunalokho ukucabanga inqubo enjalo.

Kanjani ukuze uthole ulwazi oludingayo?

Ukuze uthole ukwaziswa okwengeziwe mayelana isiqondiso emincane umthombo isignali, kubalulekile ukuba sinake nokwehlukana Harmonics umsindo. Lena isimo kubalulekile. It kuvela ukuthi indlebe kwenza kube nokwenzeka ukuba ziyombamba ulwazi mayelana nokwehlukana. Ungase futhi ufunde mayelana amplitude we umsindo harmonic. Endabeni imisindo ephansi ubuchopho nezindlebe, phakathi kwezinye izinto, ukuthola ulwazi mayelana izigaba Harmonics, futhi ngenxa yalokho, usukela esiqondisweni vibration. Yini okudingeka ngikwenze? Vele ukubala umehluko phakathi izigaba umsindo kusukela indlebe kwesokunxele nakwesokudla. Kulula ngokwanele, akunjalo? Nakuba, kulula ukuqonda inkambo iyingxenye Corti.

Isici kokucindezelwa eyengeziwe kolwazi nomsindo.START_BREAKSTART_BREAKUngamisa kakhulu ukunciphisa isikhathi sihlaziye ulwazi okwakukade wathola. Umnenke osontekile, futhi ngaleyo ndlela kungenzeka ukususa bohlu ngesikhathi esifanayo ngokuhlanganisa enothini.

Manje uyazi ukuthi kuyinto uhlaka Corti futhi yakhiwe njani. Njengoba wazi ukuthi sisebenza imisebenzi. Konke lokhu kubaluleke kakhulu futhi ewusizo ukwazi.
