Cartilage conduction

Imiyoboro ya Cartilage ninzira yerekana ibimenyetso byijwi byumvikana mumatwi yimbere . Mu 2004, Hiroshi Hosoi (Nara Medical University) yavumbuye iyi nzira ayita igikucangwa”. Kumva ukoresheje imiyoboro y'igikucangwa itandukanye ninzira zisanzwe zitwara amajwi, nk'umwuka cyangwa amagufwa, kuko bigerwaho no gukora umuyoboro ku igikucangwa no kumva  kandi ntabwo birimo kunyeganyega kw'amagufwa ya gihanga. Kubwibyo, imiyoboro ya karitsiye yitwa "inzira ya gatatu yo kumva".

Kuva mu myaka igera hafi kuri 450 ishize, inzira ebyiri zemerewe kohereza amajwi mu gutwi imbere: gutwara umwuka no gutwara amagufwa . Mu 2004, Hiroshi Hosoi, icyo gihe wari umwarimu muri kaminuza y’ubuvuzi ya Nara (ubu akaba na perezida wacyo), yavumbuye ikintu cyo kumva akoresheje urusaku rw’amatwi y’inyuma.   Muguhuza  vibura no kumva, wasangaga ijwi ryanduzwa mumatwi yimbere. Yasabye igitekerezo cy'igitabo kivuga ko karitsiye ifite umutungo wihariye utuma ishobora kohereza amajwi.  yiswe imiyoboro ya karitsiye. Kuva mu Kuboza 2022, impapuro 32 z’amasomo zasohotse kuri iyi ngingo mu binyamakuru mpuzamahanga bya siyansi. Byongeye kandi, ibyuma bifata amajwi ya karitsiye,  na terefone ngendanwa  hamwe nogukusanya amajwi  biri ku isoko kuva 2017, 2022 na 2023.

Urwego rwo kwumva rugizwe n'ugutwi, hagati, n'imbere ( cochlea ). Ugutwi kwinyuma kugizwe na pinna kwumva hanze. Pinna ikozwe na karitsiye. Igice cyimbere ninyuma cyumuyoboro wunva winyuma ukorwa na karitsiye hamwe namagufwa.  cya karitsiye hamwe nigice cyamagufwa bishobora gutandukanywa nigitutu cyoroheje nintoki. Iyo imiyoboro ishyizwe mugice cya karitsiye, ijwi rishobora kumvikana hifashishijwe imiyoboro ya karitsiye. Umwanya ukwiye wo guhuza neza ibyo bice kugirango ukorwe neza ni karitsiye ikikije ubwinjiriro bwumuyoboro wumva wo hanze, mugihe ibice biri kure yubwinjiriro (urugero, crus helicis) ntibishobora kugira uruhare runini mugutwara karitsiye.
