Umbutho kwetyala: nokwakheka umsebenzi kumasebe

Amalungu ka ukuva ivumela ukuqonda iintlobo zeentetho ehlabathini yangaphandle, ukuba siyakuqonda oko kunye nendawo. Ngenxa ukukwazi ukuva umntu ofumana ukuba bathethe baphimisele. umbutho kwetyala - izakhiwo, inkqubo entliziyweni lwe thotho lwe nganye namanye amasebe amathathu.

indlebe yangaphandle

ingxenye yokuqala imele auricle - imilo esimbaxa plate cartilaginous ezivela macala omabini wambu isikhumba kunye zangaphandle eziviwayo meatus.

Eyona umsebenzi pinna - ukwamkelwa intlokoma ive umoya. Ukususela imingxuma auricle iqala zangaphandle wamanzi eziviwayo - ubude ityhubhu-27 - 35 mm, isimo sentlalo nzulu ithambo nezenyama Amaza. Lolusu ngakwimida endlebeni emseleni ezi nesulfure nobubovu secretion onqanda kwii-zokugula iziko kwetyala. Walimala - inwebu obhityileyo kodwa oluqinile - esahlula indlebe engaphandle ukusuka kwisebe sesibini iqumrhu kwetyala, nendlebe.

nendlebe

Xa ngontsi wethambo zexeshana lo kwisisu tympanic, nto leyo eyenza ukuba inxalenye ephambili yale nendlebe ephakathi. Bezandi (Eustachian) ityhubhu - unxibelelwano phakathi nendlebe oluphakathi kunye nasopharynx. Xa yokuginya iintshukumo tube Eustachian ivula kwaye ivumela umoya ukungena kulo zendlebe, ukungqinelana uxinzelelo kwi kwisisu tympanic kunye zangaphandle umsele eziviwayo.

Endlebeni oluphakathi ziye movably amaqhina oqhagamshelwano yi ithambo ukuva elincinane - indlela elukhuni ukudluliselwa amaza ive evela zangaphandle umsele eziviwayo ukuba iiseli Besave ngeendlebe engaphakathi. Ilitye lokuqala - izando nezixholo, isiphelo elide eziqhotyoshelwe indlebe. Okwesibini - an nensimbi, edibene ithambo wesithathu incinane, nestibili. Endlebeni ukuba amabhere window okweqanda, ukusuka apho kwindlebe engaphakathi iqala. Emathanjeni, ebandakanya isebe ukuva, mancinci kakhulu. Umzekelo, ubunzima endlebeni yi mg 2.5 kuphela.

Indlebe engaphakathi

Isebe zomzimba ukuva wesithathu fanekisela nakwiingqameko (ithambo ezincinane ikhamera), imisele omise kunye nemfundo ezizodwa - ithambo ityhubhu onodonga, waziva ethotywe olephuzayo.

Le nxalenye analyzer yiacoustic, efana noqebeyi, kwaye sibizwa - njengecochlea eziviwayo.

umbutho ezindlebeni na izakhiwo ezibalulekileyo yokwakheka, ngokukuvumela ukugcina ukulingana nokuvavanya indawo umzimba esithubeni. Le eve esemfuleni omise uzaliswe fluid, futhi ngaphakathi kunye iiseli ngaphakathi ethe kakhulu. Xa umntu omnye etshintsha ukuma umzimba, kukho utshintsho lwe ulwelo imiphantsi. Ezenza esisigxina ukubana fluid kwaye zithumele umboniso malunga isiganeko ebuchotsheni. ukuva Ngoko nokulinganisela umzimba ivumela ingqondo ukufunda iintshukumo zomzimba wethu.

Inwebu, ibekwe ngaphakathi njengecochlea, iqulathe malunga 25 tysyach Imicu ubalaseleyo ubude ezahlukeneyo, ngalinye ezisabela ukuba izandi omoya ezithile kuvuliwe masixole luvo eziviwayo. Jitters ekuqaleni yatshintshelwa kwi Oblongata Medulla, uze emva koko ifikelele neuron. Kumaziko ekuva ezi zizinto ingqondo zihlahlelwe systematized, kunye result ukuba uve isandi ezalise ihlabathi.
