IAnatomy yendlebe yoMntu
Indlebe yomntu ibunjwe ngamalungu amathathu: indlebe engaphandle, umbindi wendlebe, kunye nengaphakathi lendlebe. Indlebe yangaphandle ine-pinna, i-eardrum kunye ne-eardrum. Umbindi wendlebe unawona mathambo amathathu mancinci emzimbeni, i-malleus, incus, kunye ne-stapes, ehambisa isandi sokungcangcazela ukusuka kwigubu lendlebe ukuya kwindlebe engaphakathi. Indlebe engaphakathi inoxanduva lokuguqula amaza esandi abe yimiqondiso yombane enokutolika ingqondo.
Injongo Yeendlebe
Eyona njongo iphambili yeendlebe kukuva amaza esandi aze awadlulisele ebuchotsheni ukuze acutshungulwe. Iindlebe zikwadlala indima ekulinganiseni kunye nokuqhelaniswa kwendawo. Ukongeza kumaza esandi, iindlebe zinovelwano kutshintsho lomoya kunye nokungcangcazela.
Indawo yeendlebe kwizilwanyana
Iindlebe zibekwe ngokwahlukileyo kwizilwanyana ezahlukeneyo. Izilwanyana ezininzi, ezinjengeekati nezinja, zineendlebe ezikwaziyo ukuhamba ngokuzimeleyo, nto leyo ezenza ziwufumane ngokuthe ngqo umthombo wesandi. Ezinye izilwanyana, ezifana neendlovu nemivundla, zineendlebe ezinkulu kunye ne-floppy, ezinceda ukulawula ubushushu bomzimba. Ezinye izilwanyana, ezifana namahlengesi namalulwane, zisebenzisa i-echolocation ukubona indawo ezingqongileyo kwaye azithembeli ezindlebeni zazo njengezinye izilwanyana.
Ukuzivelela kokubekwa kwendlebe
Ukuma kweendlebe kwizilwanyana kuye kwavela ngokuhamba kwexesha ekuphenduleni izinto ezahlukeneyo zokusingqongileyo. Kwezinye iimeko, iindlebe ziye zahamba ukusuka phezulu kwentloko ukuya kwicala lentloko, okuye kwaphucula ukwakhiwa kwesandi. Kwezinye iimeko, iindlebe ziye zaba nkulu okanye zintsonkothe ngakumbi ukuze zikwazi ukuva kakuhle izandi.
Izinto eziluncedo zokuBekwa kwendlebe eLateral
Ukubekwa kwendlebe ecaleni, okanye iindlebe emacaleni entloko, kuneengenelo ezininzi. Ukuba neendlebe ezimbini kumacala ahlukeneyo entloko kuvumela isandi esichanekileyo esichanekileyo. Oku kungenxa yokuba amaza esandi afikelela kwindlebe nganye ngamaxesha ahluke kancinane, nto leyo evumela ingqondo ukuba ibone icala nomgama ovela kuwo isandi. Ukubekwa kwendlebe ecaleni kwakhona kuvumela uluhlu olubanzi lokufunyanwa kwesandi.
UkuHlaliswa okuvakalayo kuBantu
Abantu bayakwazi ukuwufumana umthombo wesandi besebenzisa indibaniselwano yexesha kunye nobunzulu beempawu. Xa isandi sesandi sifika kwenye indlebe ngaphambi kwenye, ingqondo iyakwazi ukubona icala esiya ngakulo isandi. Ingqondo inokusebenzisa iiyantlukwano kubukhulu besandi phakathi kweendlebe zombini ukumisela umgama womthombo wesandi.
Indlela Ingqondo Eqhuba Ngayo Isandi
Isandi sicutshungulwa kwicortex yokuva yengqondo. I-cortex yokuva ihlalutya ukuphindaphinda, ukuqina, kunye nexesha leempawu zesandi ukufumanisa intsingiselo yesandi. Ingqondo iyakwazi ukuhluza ingxolo yangasemva kwaye igxile kwizandi ezithile.
Indima yobume bendlebe ekuveni
Ukumila kwendlebe engaphandle, okanye i-pinna, kunokuchaphazela indlela amaza esandi aqokelelwa ngayo aze adluliselwe kwindlebe engaphakathi. Iimilo ezahlukeneyo zinokukhulisa okanye zithomalalise izandi ezithile zesandi, nto leyo evumela ukubonwa ngcono kwezandi ezithile.
Imiba yaNgaphandle echaphazela ukuva
Imiba yangaphandle, njengengxolo enkulu okanye usulelo lwendlebe, inokuyonakalisa indlebe kwaye ichaphazele ukuva. Ukuvezwa kwingxolo ephezulu ekuhambeni kwexesha kunokukhokelela ekungeveni. Ukusuleleka kwindlebe kunokubangela umonakalo wexeshana okanye osisigxina kwi-eardrum kunye namathambo endlebe ephakathi.
Ukubekwa kweendlebe kubantu abangevayo
Abantu abangevayo banokuba nokubekwa kweendlebe okwahlukileyo kunabantu abevayo. Abanye abantu abangevayo basenokuba neendlebe ezincinane okanye ezingekaphuhli kunesiqhelo. Abanye basenokuba neendlebe ezibekwe ngendlela eyahlukileyo ngenxa yemfuza.
Ukubekwa kweendlebe kwezinye izilwanyana ezanyisayo
Ezinye izilwanyana ezanyisayo ziye zahlengahlengisa iindlela zokubeka iindlebe ezahlukeneyo ukuze zihambelane neemfuno zazo ezithile. Umzekelo, amarhamncwa afana neengonyama kunye namahlosi aneendlebe ezijonge phambili zokukhangela ixhoba. Izilwanyana ezizingelayo, ezifana nexhama kunye nemivundla, zinendlebe ezikwazi ukujikeleza ngokuzimeleyo ukuze zibone amarhamncwa.
Isiphelo: Kutheni iindlebe zisemacaleni eentloko zethu
Ukuma kweendlebe kumacala eentloko zethu kuvumela indawo engcono yesandi kunye noluhlu olubanzi lokubona isandi. Ukumila kwendlebe engaphandle kunye nokuma kwegubu lendlebe nako kunendima kwindlela esiva ngayo. Ngelixa izinto zangaphandle zinokuchaphazela ukuva, ukubekwa kwethu kweendlebe kunqunywe kakhulu yizinto zokuziphendukela kwemvelo kunye nelifa lemfuza.
