Ukubuka konke

Amagagasi omsindo angena endlebeni ahamba ngomsele wokuzwa wangaphandle ngaphambi kokushaya i-eardrum futhi ayenze idlidlize.

I-eardrum ixhunywe ku-malleus, elinye lamathambo amancane amathathu endlebe ephakathi. Ebizwa nangokuthi isando, idlulisa ukudlidlizela kwemisindo ku-incus, okuyidlulisela ezihlokweni. Izintambo ziphusha zingena ngaphakathi nangaphandle kwesakhiwo esibizwa ngewindi eliyisiyingi. Lesi senzo sidluliselwa kwi-cochlea, isakhiwo esigcwele uketshezi esigcwele uketshezi esiqukethe isitho sikaCorti, isitho sokuzwa. Iqukethe amangqamuzana amancane ezinwele ahambisana ne-cochlea. Lawa maseli ahumusha ukunyakaza kube yimizwa kagesi eyiswa ebuchosheni ngezinzwa zezinzwa.

Kulokhu kusika, ungabona uhlaka lweCorti olunemigqa yalo emine yamangqamuzana ezinwele. Kunomugqa wangaphakathi kwesobunxele kanye nemigqa yangaphandle emithathu ngakwesokudla.

Ake sibheke le nqubo isebenza.Okokuqala, ama-stapes amatshe abhekene newindi le-oval. Lokhu kudlulisa amagagasi omsindo ngoketshezi lwe-cochlear, kuthumele isitho sikaCorti sinyakaze.

Izintambo eziseduze komkhawulo ongaphezulu we-cochlea ziyakhala ukwehlisa umsindo wemvamisa. Labo abaseduze kwewindi le-oval basabela kumaza aphezulu.
