Limba kumva: thunthu ndi ntchito m'madi- zikulu

Ziwalo kumva zimathandiza kuzindikira zosiyanasiyana phokoso la dziko zakunja kuzindikira chikhalidwe chawo komanso malo. Ndi amamva munthu ayambe kulankhula. limba kumva - kuipidwa, finely anatsekula dongosolo la mndandanda-olumikizidwa ndi mzake m'madipatimenti atatu.

khutu kunja

gawo loyamba akuimira auricle - zovuta mawonekedwe cartilaginous mbale kuchokera ku mbali zonse yokutidwa ndi chikopa ndi kunja Makutu meatus.

Ntchito yaikulu ya pinna - kukhazikitsidwa kwa Phokoso lamayimbidwe mpweya. M'maenje mu auricle akuyamba kunja Makutu ngalande - kutalika chubu cha 27 - 35 mm, kulowa kwambiri mu fupa zosatha a Chigaza lapansi. Pakhungu kumalumikiza m'njira khutu, ndi sulfure England katulutsidwe amene kumathandiza malowedwe a matenda limba mmakutu. Likalowa m'makutu - ndi wochepa thupi koma amphamvu Kakhungu - alekanitsa khutu lakunja ku dipatimenti wachiwiri wa limba kumva ndi makutu pakati.

khutu pakati

Mu recess la fupa kanthawi ndi M'mimbamo tympanic, omwe ndi mbali yaikulu ya khutu pakati. Makutu (Eustachian) chubu - ulalo pakati pa khutu pakati ndi nasopharynx. Pamene Pomeza kayendedwe Eustachian chubu chikuyamba ndipo walola mpweya kudutsa mu khutu pakati, kuti amakhala kuthamanga mu M'mimbamo tympanic ndi kunja ngalande Makutu.

Khutu pakati ali movably cholukanalukana ndi kakang'ono kumva fupa - kuipidwa limagwirira kwa kufala kwa mafunde lamayimbidwe akubwera kuchokera ngalande kunja Makutu maselo kumva kwa khutu lamkati. Mwala - nyundo, kumapeto yaitali zaikidwa ndi likalowa m'makutu. The chachiwiri - ndi Chipala, chikugwirizana ndi fupa lachitatu kakang'ono, stirrup. Stapes kwa zimbalangondo chowulungika zenera, kumene khutu mkati amayamba. Mafupa, womwenso limba kumva, ang'ono kwambiri. Mwachitsanzo, kulemera kwa stapes ndi 2.5 okha mg.

Khutu lamkati

Wachitatu dipatimenti kumva limba ankaimira khonde (fupa kakang'ono kamera), chidwi semicircular ndi maphunziro apadera - fupa mipanda chubu mu swirling mwauzimu.

gawo ili la chowunikira lamayimbidwe, chokhala ndi nkhono, ndipo amatchedwa - ndi cochlea Makutu.

limba kumva n'kofunika nyumba anatomical, kulola kuti tikhalebe olimba ndi kuunikira malo a thupi m'malere. Izi atsiku ndi ngalande semicircular wodzazidwa ndi madzimadzi, ndi alimbane ndi mkati maselo tcheru kwambiri. Pamene munthu wasintha udindo wa thupi, pali kusintha kosangalatsa wa madzi mitsinje. Zolandilira atathana kusamutsidwa madzimadzi ndi kutumiza mbendera za chochitika mu ubongo. Choncho kumva ndi bwino thupi amalola ubongo kuphunzira za kayendedwe thupi lathu.

Kakhungu, ili mkati cochlea ndi, imakhala pafupifupi 25 tysyach ulusi abwino a amayesetsa osiyana, omwe amatipatsa ndi phokoso yeniyeni pafupipafupi natembenukira pa kutsekedwa kwa mitsempha Makutu. Jitters poyamba anasamutsa mu za medulla oblongata, kenako umalandira kotekisi ubongo. Mu malo Makutu a zikuchitika mu ubongo kusanthula ndi systematized, ndi chifukwa kuti ife tikumva phokoso amadzadza dziko.
