Lekala la utloeng: human anatomy le mosebetsi wa mafapha tse khōlō

Makala a utloeng dumella ho utloisisa mefuta e fapaneng ya melumo ea lefatše ka ntle, ho hlokomela lintho tsa tlhaho tsa bona le sebaka seo. Le bokhoni ba ho utloa motho a rua matla a ho bua. lekala la utloeng - e rarahaneng, khabeloa tuned tsamaiso ea letoto la lihlooho tse-amanang le mong le e tse ling tse mafapha a mararo.

karolo ea pele e emela auricle - rarahaneng sebopeho cartilaginous poleiti ho tloha mahlakoreng ka bobeli a le koahetsoeng ka letlalo le Link utluwang meatus.

Mosebetsi o ka sehloohong oa ho pinna - kamohelo ea loebehlana mexri tsa moea. From mekoti ka auricle qala ho Link utluwang kanale - e-ba bolelele tube, la 27 - 35 limilimithara, bophirima tebileng ka lesapo ya ntango ea lehata la. Letlalong lera le kanale tsebe, ke sebabole tšoelesa secretion eo thibela ho kenella ka hare a tshwaetso ka lekala la utloeng. Moropa oa tsebe - e tšesaane, empa matla lera - arola tsebe tsa ka ntle ho tswa ho lefapha la bobeli la lekala la ho utloa, le tsebe bohareng.

tsebe bohareng

Ka dinako tsa lesapo ya ntango ke cavity tympanic, eo ke karolo ea karolo e khōlō ea tsebe ea bohareng. Utluwang (Eustachian) tube, - sa kgokahanyo pakeng tsa tsebe bohareng le nasopharynx. Ha engole mekhatlo Eustachian tube, e qala le ho dumella moea e phunyeletse ka tsebe bohareng, e le hore leka-lekanya khatello ea cavity tympanic le Link kanale utluwang.

Ka tsebe bohareng ba movably ya kokangana ke nyenyane utloeng lesapo - e rarahaneng mochine bakeng sa phetiso ya maqhubu mexri tsoang kanale Link utluwang liseleng a ntseng a utloa ka litsebe ka hare. Lejoe la pele - hamore, qetellong telele khomaretse ho moropa oa tsebe. Ea bobeli - e tšetlo, e amana le lesapo boraro nyenyane, stirrup. Stapes ho libere oval fensetere, ho tloha eo e tsebe ka hare qala. Bones, e kenyeletsang lekala la utloa, tse nyenyane haholo. Ka mohlala, boima ba 'mele oa stapes ke 2,5 feela, mg.

Tsebe ea kelello

Oa boraro Lefapha la utloeng lekala emeloang vestibule (lesapo nyenyane khamera), le melatsoana semicircular le thuto e khethehileng - lesapo marako tube, ka swirling spiral.

karolo ena ea semanolli mexri, tšoanang e hohotse, 'me o bitsoa - the cochlea utluwang.

lekala la utloeng ke habohlokoa dibopeho anatomical, e le hore ho boloka ho leka-lekana le ho hlahloba boemo ba 'mele ka ho sebaka. Sena se etellang pele le melatsoana semicircular tletse mokelikeli, 'me lined le ka hare le ka liseleng hlokolosi haholo. Ha motho a fetola boemo ba 'mele, ho na le ke battlefield ea mokelikeli ka metjha e le. Receptors tsitsitseng displacement mokelikeli le romela pontšo ka ketsahalo e bokong. Kahoo utloa le ho leka-lekana 'mele o dumella bokong ho ithuta ka mekhatlo' mele ea rōna.

Lera, teng ka hare ho cochlea e, e na le ba ka bang 25 tysyach likhoele botle ka ho fetisisa ba bolelele fapaneng, e mong le e ba tse Karabo ea ho melumo e itseng maqhubu 'me ba sokolohela ho koalo tsa methapo ea kutlo utluwang. Jitters qalong isoa ka ho medulla oblongata, ebe fihla cortex bokong. Ka litsi utluwang tsa susumetsa ba bang boko ba li hlahlobisisa le systematized, le lebaka hore re utloa molumo tlatsa lefatše.
