Kuri benshi mubafite amatungo, mugihe bahisemo ibiryo byamatungo yumye, barashobora kwitondera cyane kurutonde rwibicuruzwa, agaciro kintungamubiri, nibindi. Ariko mubyukuri, hari ikindi kintu cyingenzi nacyo kigira ingaruka niba inyamanswa zishobora kubona intungamubiri zihagije ziva mubiryo, kandi ubwo ni bunini nuburyo bwibiryo byamatungo.Niba witegereje neza, ntabwo bigoye kubona ko ibiryo byimbwa kumasoko mubisanzwe bizunguruka, kandi hariho na kare na shusho;imiterere yibiribwa byinjangwe ni mpandeshatu, pentagon, imeze nkumutima, hamwe na plum, mubisanzwe bifite impande nyinshi.Ibyokurya byinshi byimbwa mubisanzwe binini kuruta ibiryo byinjangwe.
Ⅰ.Impamvu zigira ingano nubunini bwibiryo byimbwa ninjangwe
- Imiterere yinyo yimbwa ninjangwe iratandukanye
amenyo y'injangwe：
Imbwaamenyo：
Ibiranga isura nimiterere yimbwa ninjangwe biratandukanye cyane.Impera yikamba ryinyo yinjangwe irakaze cyane, cyane cyane premolars ifite udusimba 4 kuri kamba.Ibibyimba byo hejuru ya kabiri na hepfo ya mbere ya premolars nini kandi ityaye, ishobora gutanyagura uruhu rwumuhigo, bityo bita fissure.iryinyo.Umunwa w'injangwe ni ngufi kandi ngari: amenyo 26 yimeza n'amenyo 30 ahoraho;umunwa wimbwa ni muremure kandi ufunganye: 28 amababi na menyo 42 ahoraho.
Ugereranije n amenyo yamababi, amenyo ahoraho yinjangwe afite andi magi ane kumpande zombi zo hejuru no hepfo.Hariho impinduka nyinshi mumenyo ahoraho yimbwa.Ugereranije namenyo yamababi, hariho andi menyo 14.Ni premolars 4 kumpande zombi zo mumasaya yo hejuru no hepfo, imishwarara 2 ibumoso n'iburyo bwo hejuru, hamwe na 3 mumasaya yo hepfo.
Imbwa zoroshye kandi zinyo zituma zihekenya ibiryo nkuko abantu babikora.Iyo imbwa ihekenye ibiryo, amenyo arashobora kugenda igihe kirekire + kuruhande, kumenagura + gukata + gusya ibiryo.Injangwe zifite umuvuduko muke hamwe numubare muto wa molars na premolars, kuburyo zishobora kugenda igihe kirekire mugihe cyo guhekenya ibiryo, gukata no kumenagura ibiryo hamwe namenyo yabo.Nukuvuga ko imbwa ziruma hejuru no hasi, mugihe injangwe zisya inyuma.
2. Ingeso yo kurya imbwa ninjangwe ziratandukanye
Imbwa n'injangwe ni inyamanswa, ariko imbwa zifite ibiryo byinshi kuruta injangwe, kandi ibyo bakeneye ku nyama ni bike cyane ugereranije n'injangwe, ibi rero bivamo amenyo y'injangwe bigomba kuba bifite ubushobozi bwiza bwo gufata inyama, kandi injangwe zikarishye amenyo., ityaye, kandi ifite ubushobozi bwo gukata.Iyi miterere irakwiriye cyane kugirango itanyagure inyamaswa nto nkimbeba ninyoni mo kabiri.Iyo urya, injangwe zishingikirizaho ubwazo kugirango zikure.Ururimi rujanjagura umuhigo mo uduce duto twinyama.
Injangwe zishobora kubona ibiryo byuzuye muburyo butandukanye, cyane cyane guhekenya amenyo cyangwa gufatisha ururimi.Kubwibyo, uburyo bworoshye bwibiribwa byoroshye kubwa njangwe, niko byemerwa.Nta buryo bwihariye bwimbwa zibona ibiryo.Nyamara, amenyo ya brachycephalic, asohoka imbere yinyoye biragoye kuruma, kandi izo mbwa zihitamo gukoresha ururimi rwabo mubiryo.
Ubwoko butandukanye bwimbwa ninjangwe bifite akamenyero ko kurya:
Dufashe injangwe ebyiri mu njangwe nk'urugero, Garfield n'injangwe z'abashumba b'Abashinwa, birashobora kugaragara ukurikije imiterere yo mu maso ko bafite itandukaniro rigaragara, kandi iri tandukaniro rizagira ingaruka kubyo barya.Mbere na mbere, isura ya Garfield igaragaza ko idashobora kurya ibiryo byumye ugereranije neza cyangwa kunyerera, kandi iki ntabwo ari ikibazo gikomeye ku njangwe z'abashumba b'Abashinwa.
Icya kabiri, mugihe umunwa wa Garfield urimo kurya, ntashobora kurya ibiryo byinjangwe byumye hamwe nuduce twinshi, kandi hamwe nibiryo bingana, umuvuduko wo kurya wa Garfield ushobora gufatwa nkuwatinze cyane.Cyane cyane uruziga, ibiryo binini byumye biragoye kubarya no guhekenya.Ibibazo nkibi bibaho no kurwana nimbwa.
