Khutu lamkati. Kapangidwe ndi ntchito.

khutu imatengedwa zovuta vestibular limba kuti ndi udindo pogwira ntchito ziwiri. Iwo amaona mafunde chilema udindo chingakuthandizeni ndipo amatha kugwira thupi danga mu malo ena. Khutu - ndi wophatikizidwa limba ili fupa zosatha a Chigaza ndipo okha auricles kunja. khutu ukufanizidwa ndi madipatimenti atatu, omwe ndi udindo ntchito zina: lakunja, pakati komanso mkati.

Khutu lamkati. Kapangidwe.

Kapangidwe mkati mwa makutu pang'ono ngati nkhono ndi (ichi ndi chifukwa chake ali ndi mayina ofanana), ndipo ndi zovuta dongosolo tubular, wodzala ndi madzi. Khutu mkati ili mu kuya kwa fupa wosakhalitsa, ndi zigawo ziwiri - ndi cochlea (a Makutu limba) ndi ngalande semicircular (mgwirizano limba).

Matupi mzati weni weni wa zvukovosprinimayuschego zida ndi vestibular chowunikira, amene ali ndi udindo kwa thupi udindo mu mlengalenga, chifukwa ntchito yokonza mgwirizano, komanso minofu kamvekedwe. Anatomical commonality kachitidwe awiriwa n'kofunika kwambiri, ndi vutoli awo zingachititse osati ndi mavuto kumva, komanso ntchito ya matenda vestibular, mbali yaikulu ya ndilo kusanza, chizungulire.

Mumtima khutu bwino limba

The zida vestibular kapena chiwalo cha mgwirizano wapangidwa chidwi semicircular, amene anakonza mu ndege atatu perpendicular, ndi sacs tiwiri. Perilymph kudzaza njira, mkati limene pali ngalande ena odzazidwa ndi endolymph, iwo kulankhula ndi mitsinje ya cochlea lapansi. Imalandira molekezera mitsempha mawonekedwe nyemba kuti kuyankha zofuna za mutu, ubongo linaŵerengera mmene thupi pabwino poyerekezera ndi mutu.

Pali zinthu pamene maselo vestibular kupanga nyemba pa zifukwa zosiyana kwambiri kuposa mutu akutembenukira. Zinthu ngati kumachitika mu kutukusira kwa khutu mumtima, kapena ena pathologies Mwachitsanzo, pamene anamasulidwa mu meatus Makutu kwambiri otentha kapena ozizira kwambiri madzi. Zikatero, kungakhale Timatha nseru, chizungulire, ndi imfa lathu mu mlengalenga.

limba kumva

Khutu mkati ndi udindo kumva zomverera. Sound mafunde mwa zenera chowulungika mu khutu mkati ndi chifukwa zoyenda madzimadzi ndi Phokoso la villi ting'onoting'ono. Villi kutembenuza Phokoso ku zikhumbo kuti mitsempha Makutu kulowa ubongo, ndipo ubongo kenako amachititsa kusintha awo mu zithunzi Makutu.

Khutu mkati ndi udindo pafupipafupi kudziwika chifukwa umene munthu amatha kusiyanitsa phokoso wina ndi mzake. Zovuta unyolo njira electromechanical wa khutu mkati amagwiritsa ziwalo zanga zonse, kotero kuti kumva mu dongosolo la iwo onse ayenera ntchito bwino. Ngati nthawi zina njira izi ndithu, akumva.

Kumva imfa - ndi chosayenerera ambiri khutu lamkati

Phokoso m'khutu yodziwika ndi zinthu monga matalikidwe ndi pafupipafupi. Matalikidwe - ichi ndi mphamvu zimene phokoso limayendera umalimbikitsa Kakhungu, pafupipafupi, nayenso Mzimuyo chiwerengero cha Sonic yoweyula oscillation, amene amachita mwa lachiwirilo. Amalephera kusiyanitsa phokoso ndi kudziwa mafurikwense ena otchedwa kumva imfa. Kumva imfa kungakhale conductive, sensorineural ndi kusakaniza. Sensorineural kumva imfa ndi kuphwanya tilinazo wa cochlea kapena Makutu mitsempha ntchito pansi. Conductive kumva imfa - kuphwanya conduction pakati pa akunja ndi makutu pakati, kuphatikizapo kumva imfa akuimira anthu ndi matenda ena.
