Yintoni na iqumrhu Corti?

Abaninzi banomdla kweli isebe Corti kunye nemisebenzi yayo. Yiba ubuncinane uluvo eshwankathelwe nto ukuba wonke. lungu Corti bukaThixo ibizwa ngokuba yinxalenye engabalulekanga yinto yokuncedisa ukuva. Le ibekwe kwi ekulo membranous. Ekuhambeni izinto zazivelela ngokwesiseko umgca osecaleni (oko kukuthi, izakhiwo zazo) yaye liphuhlise le yinxalenye analyzer ive.

Yena uchola amaza lokungcangcazela ukuba kwi mibono ka kwindlebe engaphakathi, yaye emva koko athumele ukuba kwinxalenye eziviwayo le neuron, kangangokuba kukho imbono yesandi. Lo umbutho Corti inomsebenzi ebalulekileyo. Oku kulapho uhlalutyo sokuqala ukubunjwa wenza iintlobo Imiqondiso odiyo. Lo mzimba kuqala wafumanisa Alfonso Corti - histologist Italian.

Iphi na iqumrhu Corti?

Le ise kwikhosi cochlear apho perilymph kunye endolymph, yaye imele i ekubeni kukho ingamathambo, efana saya. Inxalenye eliphezulu ebaleka ezikufutshane ngezinyuko ebizwa njalo-vestibular. Ibizwa inwebu Reissner kaThixo. A inxalenye ephantsi, ibekwe kufuphi tympani scala, iquka inwebu eziphambili ziqhagamshelane lamina osseous spiral.

Injongo Isakhiwo

Lo umbutho Corti ukwakweli inwebu engundoqo, oko akhiwa iiseli iinwele nomphandle wocango kunye nenkxaso. Ngokomzekelo, ipali-phambili. Kwakhona iquka iiseli Hensen kunye Deiters kaKlawudiyo Kesare. Kubo yaye ke iqumrhu Corti. Phakathi kubo itonela apho ukwandisa axons kwi luvo ekubeni spiral node. They sukela nokusabela iziganeko isandi iiseli iinwele. Nevuthisayo ngexesha ke, ulale ezingontsingontsini wadala ngokuxhasa imizimba iseli. Kumphezulu wazo wajika ukuyifezekisa amalungiselelo ikhava inwebu ukususela-30 ukuya kuma-60 iinwele kunokuba elifutshane. Ukuxhasa iiseli eyenziwa njengoko umsebenzi trophic. Njani na? Bathumela iiseli iinwele kwezondlo. Indima yeziko Corti - inguqu intlokoma olunzulu amandla luvo excitation. Ukuze benze oku, enyanisweni, alisweleyo. Nantso into umsebenzi licandelo Corti. Histology uvumela ukuba uqhelane kunye nesakhiwo sayo.

zomzimba

Le walimala luzobe intlokoma aphilileyo ngokusebenzisa amathambo akhiwe zendlebe, kweyela eliphakathi engamanzi - endolymph kunye perilymph. iintshukumo zabo igalelo yokuba inwebu nesigqubuthelo licandelo Corti isuntswana zisuswe iiseli iinwele. Kwenzeka ntoni ngenxa yoko? iinwele zokuqala bent. Ke biopotentials ukuba zibonwa ganglion Ukonakala (okanye mandithi, iinkqubo zakhe neuronal). Beza emazantsi zonke iiseli iinwele. Ubume licandelo Corti umdla omkhulu kubaphandi abaninzi.

enye ingcamango

Kukwakho uluvo eyahlukileyo ngalo mbandela. Ngokutsho kuyo, iiseli iinwele umzingeli'beeps - kuphela eriyali enovakalelo depolarized kukungakhuseleki efika ngamaza. A indima ebalulekileyo idlalwa apha yi acetylcholine endolymphatic. Depolarization kusungula ukulandelelana utshintshwano kwemichiza iiseli iinwele, ezizezi xa kukho icytoplasm zabo. Emva koko, wadibana nabo kwalapho izakuvela imiyalezo luvo. Ngesandi intlokoma kunokuba ukuphakama ezahlukeneyo. Ngokuba elowo kubo ke yinxenye olwahlukileyo ngaba umbutho Corti. frequency High lokungcangcazela ukuze bandiqumbise iinxalenye cochlear zibekwe kufutshane emhlabeni, kwaye ephantsi - ngaphezulu. Oku kungenxa ngezenzeko hydrodynamic kwi njengecochlea. Lo mbutho Corti, imisebenzi ezaziwa ngoku wena ukuba udlale kule nkqubo yonke indima ebalulekileyo.

Kubonakala ukuba njengenkumba lungathathwa onefuthe ngomatshini of impendulo frequency: wesenzo, oko kufana igama lakhe. Kodwa microphone akukho efanayo kakhulu.

Kutheni le nkqubo ibaluleke kangaka?

Ngenxa iimpawu ngentla, ingqondo nako ukuphendula izandi ezithile kwaye hayi ukuphumeza i Fourier inguqu, ngaphandle koncedo kwimathematika (endleleni, kuba aswele amandla ama) ukuyisombulula le, imithombo yolwazi kuthinjwa. Bekuya kuba nzima kakhulu. Kulula ukuqonda ukuba yintoni na umbutho Corti, kunokuba ukucinga inkqubo enjalo.

Indlela ukufumana ulwazi oludingayo?

Ukuze ufumane inkcazelo engakumbi malunga kwicala emboxo yomthombo umqondiso, kuyimfuneko ukuba banikele ingqalelo kule nokwehlukana harmonics yesandi. Le yimeko ebalulekileyo. Kubonakala ukuba le indlebe yenza kube lula ukuba athimbe inkcazelo malunga nokwehlukana. Unako kwakhona ufunde malunga awo izandi harmonic. Kwimeko ezitsho ephantsi ingqondo kunye iindlebe, phakathi kwezinye izinto, ukufumana ingcaciso malunga iimbonakalo harmonics, yaye ngoko, ingalandwa ulwalathiso lokungcangcazela. Yintoni ekufuneka ukuba ndenze ntoni na? ukubala nje umahluko phakathi izigaba isandi ukusuka indlebe ekhohlo nasekunene. Kulula ngokwaneleyo, akunjalo? Nangona, kube lula ukuqonda ke ukuba ilungu Corti.

Faka ucinezelo eyongezelelweyo ingcaciso evakalayo nga kakhulu ukunciphisa ixesha ukuhlalutya inkcazelo yamkelwe. Nkumba ejijekileyo, kwaye ke ngoko kunokwenzeka ukususa kuyoyonke ngexesha elifanayo edibanisa ngelamadoda ilizwi.

Ngoku uyazi ukuba ngaba umbutho Corti kwaye yakhiwe ngayo. Njengoko usazi ukuba wenza imisebenzi. Konke oku kubaluleke kakhulu yaye luncedo ukwazi.
