Izingxenye ezithile zomzimba ziqhubeka zikhula
Cabanga usuqedile ukukhula? Uvula izingxenye ezithile zomzimba zilokhu zikhula, ngisho nangemva kokuba wonke umzimba wakho ukhule ngokugcwele. Uma ubuke amalungu omndeni asebekhulile adala eminyakeni eminingi noma uzibheka esibukweni, ungase usole ukuthi impumu ingenye yalezi zici zobuso eziguqukayo. Izinyosi zethu ziyaqhubeka zikhula njengoba sisebudala, ngenxa yokushintsha kwezicubu ezithambile, imisipha, ukuqina kwesikhumba kanye ne- cartilage eyenza isakhiwo esiyisisekelo somswakama.
Ngokungafani namathambo, i-cartilage iyaqhubeka ikhula ngokuhamba kwesikhathi.
Yikuphi UCwaningo Olusitshelayo
Ucwaningo oluningi luye lwahlola izinguquko ekhaleni phakathi kwamalungu ezizwe ezahlukahlukene, kuhlanganise nenye eyanyatheliswa ku-Forensic Science International. Ucwaningo lubuka labo baseShayina, amaNdiya, amaMalaysia, abaphakathi baseYurophu nabase-Afro-American futhi bahlola ukuthi ingabe ikhala liyashintsha kanjani ngobudala kanye nezinguquko ezithile ezenzekayo. Zombili izifundo zesikhathi esigcwele kanye nedatha ehlukaniswayo ibonisa ukuthi abantu asebekhulile bavame ukuba nezindwangu ezinkulu kunamalungu amancane obulili obufanayo noma uhlanga. Lo mkhuba uqhubeka phakathi kwezinhlanga eziningi ezifundwe.
Abacwaningi e-Functional Anatomy Research Center (FARC) eMilan bhala ukuthi isimo sokushintsha kwezinyosi sinesithakazelo kakhulu odokotela abahlinzayo abahlinzekela ukulungisa izinguquko zobuso ngokuphathelene nezinqubo ezifana ne-rhinoplasty. Ukwengeza, ososayensi bezobunhloli babethembele emininingwaneni enembile yokuguga ebusweni emizamweni yabo yokukhomba izisulu zobugebengu, ukuqoqa idatha emasendlini okuhlala kanye nezithombe zabantu abadala abalahlekile.
Ukunquma ukuthi ikhala liyashintsha kanjani esikhathini sokuphila, abacwaningi bahlaziya izithombe ezintathu zabafundi abangaba ngu-900 baseCaucasus phakathi kweminyaka engama-4 no-73. Bahlolisisa "izindawo eziphawulekayo" zomzimba: ukuphakama, ubude bridge, ubude bamazinyo zombili, ukuphakama kwendwangu kuya kwesilinganiso sokuphakama kwesisindo, ububanzi besisindo kanye ne-tip angles.
Bese bahlela idatha ngeminyaka nobulili.
Indlela I-Nose Ishintsha Ngayo Iminyaka
Ngokucwaninga abacwaningi be-FARC, zonke izilinganiso zithinteka kakhulu ngobudala. Umthamo we-nasal, ukuhamba kwendawo kanye ne-liner kwanda. Ngamanye amazwi, bathole ukuthi izinduku zikhula ngokuhamba kwesikhathi. Esinye ukutholwa okuqhubekayo ukuthi i-tip ye-tip yangasese - i-angle edalwe eceleni kwebhuloho lempumu, eduze kwethiphu kuya esikhaleni esingaphansi kwendlebe engenhla - iyancipha, okusho ukuthi ikhala livame ukuqhuma ngeminyaka.
Kusukela ebusheni kuya ekugugeni, ukukhula kwezicubu ezithambile zomzimba kwakunkulu futhi kwenzeka ekuqaleni kwamantombazane asetsheni kunabantwana abaneminyaka efanayo. Ukuphakama kwe-nasal kwandisa kakhulu, kabili kabili kusukela ekuzalweni kuya eminyakeni engama-20 noma ngaphezulu. Ngokuvamile, abesilisa banamaconsi amakhulu kunabesifazane, kodwa izinyosi zibonakala zikhula ngokushesha kumantombazane kunabantwana uma izilinganiso ziqhathaniswa nokuphila konke. Kwabesifazane abaneminyaka engu-3 kuya kwengu-4 ubudala, umthamo wezindebe ezilinganiselwe wawuyizingxenye ezingamaphesenti angu-42 ubukhulu obufinyeleleke lapho umuntu esekhulile, noma uneminyaka engu-18 kuya kwengu-30 ubudala. Kubesilisa, ivolumu evamile yayingama-36%.
Ngesikhathi umuntu omdala efinyelela eminyakeni engama-30 noma ngaphezulu, ukukhula kwempumu kunciphisa kakhulu. Phakathi kweminyaka engama-50 no-60 ubudala, umthamo wamanzi emadodeni uzovame ukwanda ngamanye amaphesenti angu-29; kwabesifazane, amaphesenti angu-18.
