Ngesikhathi sokuzalwa, ngokulinganisela umzimba, indlebe yangaphandle yayinkulu kunenkulu ikhanda futhi yaqhubeka nokukhula ngendlela elula empilweni yonke, ifinyelela izindlela eziphezulu kakhulu kubafakazi abadala ngaphezu kwe-85 yrs.
Ingabe izindlebe zakho ziyeka ukukhula nini na?
Amathambo ayeka ukukhula ngemva kokuqina. Kodwa i-cartilage, isakhiwo esifana neplastiki emindlebeni kanye neminwe yethu, siyaqhubeka nokukhula. Hhayi kuphela ukuthi i-cartilage ikhula, kodwa nezindlebe zokugxumela ziyanda kusukela ezimpini, okungenza izindlebe zibukeke zinkulu kakhulu.
Ingabe izindlebe zikhula kakhulu ngokuba umuntu ehlisa?
Lolu cwaningo luxhasa umbono wokuthi uma abantu baphila, izindlebe zabo zikhula kakhulu, ikakhulukazi isilinganiso sezindlebe, esikhula ngokulinganisela 0.51 mm ngonyaka. Lokhu ukukhula kungenzeka kuhlobene nemiphumela yokukhula kwe-collagen.
Iziphi izinhlobo zomzimba ezingekho ukukhula?
Noma ingxenye yethu yomzimba ishintsha uma sikhula, amazwane ethu, izindlebe zokugxumela kanye nezinhlobo zezindlebe zikhula. Lokhu ngoba kwenziwe kakhulu amaceli we-cartilage, okuyinto ahlukanisa kakhulu uma sikhula.
Ingabe izindlebe zakho zilingana usuku lokuzalwa?
Impumulo yethu nezindlebe ziyakhula, kodwa amehlo ethu alingana usuku lokuzalwa. Kuthunyelwe: Okthoba.
Ingabe Izindlebe Zakho NeMpumulo Ziqhubeka Nokukhula Uma Uhlala Ukhula
Yini usayizi ophelele wezindlebe?
Indlebe ephelele futhi iyehla emuva ngezilinganiso efanayo nezimpumputhe. Kwabesifazane, indlebe yomuntu omdala ingu-59mm ukuphakama futhi indlebe yendoda ingu-63mm ukuphakama. Kumaqhawe, ubude bendlebe bungu-48mm eminyakeni engu-6 eyikhulu, bese kuya kwe-55mm eminyakeni engu-5 futhi kwe-59mm eminyakeni engu-10. Izilinganiso ziyancipha kancane kwabesifazane.
Iindlebe ezinkulu noma ezincane zinhle kakhulu?
Umsebenzi wendlebe yangaphandle, noma iphinna, ukukhuphula futhi ukudlula umsindo endleleni yezindlebe. Iindlebe ezinkulu zenzela lokhu ngokwengeziwe, kodwa ngenxa yokuthi iphinna ikhuphula amasayithi ngezingu-15 decibel (ukulinganisa, ukhulumi ngezansi kungaba amasayithi angu-30), ushintsho luyancane kakhulu ukwenza umehluko omkhulu.
Yiphi iqoqo elingakwazi ukuzizwa?
Izinyo ngumzimba WEDWA ongakwazi ukuzinzwa. Ukuzinzwa kusho ukuthi nokukhulisa okulahlekile noma ukuliphindisela ngokugcina.
Yini iqoqo elikhula kancane kakhulu emzimbeni?
IMPENDULO: Inqubo eyodwa yomzimba omdala ongekho ekukhuleni kusukela ekuzalweni kuya ekufeni yindlebe yangaphakathi noma i-‘Stapes’.
Yini inqindi eliqinile kakhulu emzimbeni?
Inqindi eliqinile kakhulu ngokulinganisa kumiswa yalo yindlebe yomuntu omdala. Ngazo zonke izinso zomlomo zisebenza ndawonye, zingavala izinyo ngenani elikhulu njengoba-55 amapawundi (ama-25 kg) kumazinyo angaphambili noma amapawundi angu-200 (ama-90.7 kg) kumazinyo amakhulu.
Iphi ingxenye yomzimba iqala ukukhula kuqala?
Njengoba ukukhula kwesikhathi sokubaleka kugcina, izibuko zokukhula zivutha, futhi ekupheleni kwesikhathi sokubaleka ziyavimbela futhi ziqale ukukhula. Isiqukathi esigcwele somzimba asikho esiphelile esiyekile ukukhula ngasikhathi sinye; izandla nezinyawo ziqala kuqala, bese izandla nezintandane, ngezinye izikhathi zokukhula zikube isibhamu.
Izindlebe zingakakhulu zingakakhulula?
Ubude obukhulu bezindlebe kwabesifazane kwaba yi-52 mm (SD +/- 4.3 mm) ngokusivela, 61 mm (SD +/- 3.9 mm) ngo20 yobudala kanye ne-72 mm (SD +/- 4.6 mm) kubantu abadala kune-70 yrs. Kwezinsubject zesilisa, lezi zinani ezintathu zazilolu: 52 mm (SD +/- 4.1 mm), 65 mm (SD +/- 4.0 mm) kanye ne-78 mm (SD +/- 4.8 mm), ngokulandelana.
Yini esenza izindlebe zibe mkhulu?
Kubantu abaningi, izindlebe ezivulekile noma ezimkhulu zinikezwa ukuthi i-folding antihelical ayivuthi kahle. Lapho i-antihelical fold ingavuthi kahle, kwenza ukuthi i-helix (umkhawulo wangaphandle wezindlebe) ukhiphe phandle (buka i-diagram ye-ear yangaphandle ephethe).
Yizindlebe zishintsha isimo ngenkathi sidlula?
Njengoba udlula, ithuba likwenza ukuthi ikhathijhi emadlebeni nezindlebe lihlaziywe futhi liwe. Lokhu kwenza izici ezide, ezinde ngaphezulu. Izifundo ziqonde ukuthi izindlebe zikhula ngezinga elilungele .22 millimeters ngonyaka.
Yini umgodi wendlebe ongajwayelekile?
Umgodi wendlebe ongaphandle ongajwayelekileUmgodi wendlebe uhlala njengelitha le-C, okudalwa ngohelixi kanye nesilungu sendlebe. Ngaphakathi kwelitha le-C kune-litha le-Y, okudalwa ngantihelixi kanye ne-crura ephezulu nezansi. Inhlangothi eyinhloko yendlebe ihlala njengesivalo sasehlobo, futhi ibizwa ngokuthi yi-concha.
Yini okusho ukuthi amadlebe amakhulu?
Ukuchaza. ukuba nosy futhi ulalele izingxoxo zabantu abanye abazungezile.
Yingaphi ingxenye yomzimba eyakhula kuze kufike ekufeni?
Ukuchaza: Ukukhula kwemigodi eminingi (amasosha, amathambo njll …) womzimba wabantu kuyaqedwa emva kwezinsukwana zobudala. Kodwa khona lapha ingxenye eyodwa ethile eyaziwa ngokuthi yi-cartilage eyaqhubeka nokukhula kuze kufike ekufeni.
Yini ingxenye eyenziwe engabuthakathaka kakhulu womzimba?
U-Stapedius, inyama yothambo elincane kakhulu womzimba wabantu, eyidumela elilodwa, ilalelwe ukuba inyama engabuthakathaka kakhulu.
Yini ingxenye eyenziwe esifushane kakhulu yomzimba?
Ngokufanele, lokho kungaba u-stapes. Yingxenye yamathambo amancane amathathu esindlebeni saphakathi ephathisa umsindo kusuka esindlebeni sangaphandle kuya esindlebeni sangaphakathi.
Yingaphi ingxenye yomzimba engazizwa ukunyanya?
Ibhalo alikho nociceptors – amanethi okubona ukuthi umzimba wethu unokuthi nokuthi kungani, futhi kubikise lokhu esibambo sebhasi nebholumu. Lokhu kudalwe ukukholelwa ukuthi ibholumu alikho ukunyanya.
Yiliphi iqoqo elingaphiliswa ngaphandle kwayo?
Ungaphila impilo ephakeme ngaphandle kwelinye iqoqo lakho, ikhanda, isipuni, umhlathi, igal blada, amadenoyidi, amatonisili, kanye namanye amashashalazi, amathambo wefibula avunyelwe emilenzeni yombili kanye nezikhukhula eziyisithupha.
Yiliphi iqoqo elingabuyela emuva?
Isibindi sinenkambulelo ehlukile phakathi kwezinqoqo zokuthi singabuyela emuva ngemva kokulimala. Isibindi singabuyela esiswini esijwayelekile nanoma kuze kube 90% kwalwo alukhishiwe.
Ingabe amadlebe amakhulu ayathokozisa?
Kubonakala sengathi amadlebe amakhulu anezinhlamvu ezinkulu zokulondolozwa. Abantu abanawo bayacabanga ukuthi banesithakazelo empilweni. Kungase kube nokuthi babe neminyaka emnandi yabantwana bese baphumelela njengabadala. Ngokufanayo, uma umuntu enomhlathi ophucukile, kungase kube nokuthi ahlome kwezimali eminyakeni yakhe yesine nanye.
