Amphaka ambiri a abwenzi ndi agalu saukitsidwa kuyambira ubwana, kotero ndikufuna kudziwa kuti ali ndi zaka zingati? Kodi ikudya chakudya cha ana agalu ndi ana agalu? Kapena idyani galu wamkulu ndi mphaka? Ngakhale mutagula chiweto kuyambira ubwana, mudzafuna kudziwa kuti ziweto zili ndi zaka zingati. Kodi ndi miyezi iwiri kapena miyezi itatu? M'ma zipatala, nthawi zambiri timakonda kukhala ndi zaka za ziweto kudzera mwa mano.

Pali kusiyana kwakukulu pakati pa mano chifukwa cha chakudya chosiyanasiyana, kugwiritsa ntchito mano akupera zoseweretsa ndi ana am'madzi, pomwe kutaya mtima kumatha kukhala kwakukulu kwa agalu akuluakulu. Zachidziwikire, omwe amatchedwa kutinso amakhalanso ndi modekha. Galu wazaka 5 nthawi zonse amadya mafupa, ndipo kuvala mano kumafanana ndi galu wazaka 10. Koma simungathe kukumana ndi galu wazaka 10 wokhala ndi mano omwewo ngati galu wazaka 5. M'mbuyomu, ndinakumana ndi mwini ziweto yemwe amabweretsa tsitsi lagolide wazaka 17. Ndiye chinthu chachikulu. Ikufunika kudziwa zaka ndi matenda owoneka bwino asanamulandire. Akuti ali ndi zaka 7 mukatsegula pakamwa panu kuti muwone mano. Kodi sikulakwa kukumbukira zaka za agogo ake?

Zachidziwikire, mukakhala achichepere, mutha kudziwanso matenda ambiri a ziweto pomaona mano awo, monga ngati akusowa calcium ndipo muli ndi mizere iwiri. Chifukwa chake ndikofunikira kuphunzira momwe mungayang'anirire kukula kwa mano ndikuweruza zaka zawo komanso thanzi.

Galu amayamba kukula mano osawerengeka 19 mpaka 20 atabadwa; Pamasabata 4-5 okalamba, chifuwa choyamba ndi chachiwiri chimakhala kutalika kwake. Pakatha masabata 5-6, acisolo achitatu alinso; Kwa ana agalu azaka 8

Mu miyezi iwiri ya kubadwa kwa miyezi iwiri ya 2-4, agalu anayamba kusinthana mano pang'ono, ndipo astisoki woyamba anayamba kugwa ndikukula. A Victor wachiwiri ndi wachitatu ndi ukadaulo wasinthidwa ali ndi zaka 5-6 miyezi; Ali ndi miyezi 8 mpaka miyezi 12, ma molars onse amasinthidwa ndi mano okhazikika (mano osatha). Mano okhazikika amakhala oyera komanso owala, ndipo osowa amakhala ndi mawonekedwe akuthwa. Ngati pali chikasu, zikutanthauza kuti tartar ndi tartar;

Galu atakwanitsa zaka 1.5-2, nsonga yayikulu ya istibur infor (calsor) imatha, ndipo imakupukusa ndi chimbale chaching'ono, chomwe chimatchedwa Peak chimatha; Pazaka za 2.5, cusp ya yachiwiri ya mandiblar insular (dzino lamkati) lidatha; Ali ndi zaka 3.5, nsonga ya maxillary iscisor idavala; Ali ndi zaka 4.5, Cusp ya dzino la Mixtillary limatha; Uku ndi kutha kwa unyamata wa galu. Dzino limasintha pakakhala nthawi imeneyi sizikhudzidwa ndi zaka zambiri kuposa zomwe zimachitika pang'onopang'ono.

Popeza galuyo anali ndi zaka 5, wachitatu wam'mimba ndi cannine cusp anali atavala pang'ono (osavala), ndipo chachiwiri ndi chachiwiri chinali makona akona; Ali ndi zaka 6, chipani cha lachitatu maxillary chipongwe chinavalidwa pang'ono, ndipo mano a cannine anali owuma ndi kuzungulira; Ali ndi zaka 7, agalu a ma agalu akuluakulu adavala muzu, ndipo pogaya anali wofuula; Ali ndi zaka 8, agalu a ma agalu akuluakulu amavala ndi kuyamwa; Ali ndi zaka 10, kuvala kovutirapo wachiwiri wa Mandibur ndi maxillary incisor inali yayitali kwambiri; Agalu akulu nthawi zambiri amakhala zaka 10 mpaka 12, ndipo nthawi zambiri samakhala ndi mano akutsika, omwe nthawi zambiri amakhala kuvala kwakukulu;

Galu akakhala ndi zaka 16, ili ndi nthawi yayitali, kapena kuti ndi galu wakale. Zovuta zimagwera, mano a canine ndi osakwanira, ndipo chofala kwambiri ndicho mano achikasu; Pazaka za 20, mano a canine adagwa, ndipo kunalibe mano mkamwa.

Poyerekeza ndi agalu nthawi zambiri amakakamiza zinthu zovuta kuzikutira mano, zomwe zimapangitsa kuti zikhale zovuta kuweruza zaka chifukwa cha kuvala mano. Mano a amphaka amakula pafupipafupi ndipo amatha kugwiritsidwa ntchito ngati mulingo wabwino kwambiri woweruza wazaka.

Mano a canine a amphaka amakhala otalikirapo, olimba komanso akuthwa. Mano a canine ali ndi muzu wa mano komanso nsonga ya dzino. Mtambo wamkamwa ukatsekedwa, mano apamwamba a canine amapezeka kumbali ya mano am'madzi a cannine. Pali kusiyana kwa dzino la canine. Prengo yoyamba ndi yaying'ono, prepola wachiwiri ndi yayikulu, ndipo malangizo achitatu ndiye wamkulu kwambiri. Pulogalamu yapamwamba kwambiri komanso yotsika imapangidwa ndi malangizo a mano anayi. Mfundo yakumkati ndi yayikulu, yakuthwa, ndipo imakhudza thupi long'amba, motero amatchedwanso dzino logawanika.

Mphakayo imakula bere lake loyamba loyambirira limakokedwa ndi masabata 2-3 atabadwa; Zosowa zachiwiri ndi zachitatu ndi ziphunzitso zimapangidwa mozungulira 3-4;

Amphaka amakula osakhazikika ndipo chachiwiri kuti musinthe chifuwa cham'mimba pafupifupi 3.5-4; Ali ndi zaka 4-4.5, lumo lachitatu likuyamba m'malo mwa bere; Mano a canine amakula pafupifupi miyezi 5 kuti asinthe mano a ana a canine;

Mphaka imakula mano pamutu pafupifupi miyezi iwiri; Pulogalamu yachiwiri ndi yachitatu ija imamera pa miyezi 4-6, ndipo pang'onopang'ono imasinthidwa ndi zikhomo zosakhazikika; MORORO yoyambirira yoyambirira imamera pa miyezi 4-5. Kuyika kwa dzino kumayiko za amphaka kuli pafupifupi miyezi 4-6. Munthawi imeneyi, atha kusowa chilako cha mano.

Mphaka itatha ndi chaka chimodzi, zokutira zake zimayamba kuvala; Pambuyo pa zaka 7, mano a Cat a Cat adayamba kukhala ndi zaka pang'onopang'ono, ndipo ziphunzitso za mandibolar zidazingidwa; Pambuyo zaka 10, mano akutsogolo a nsagwada ya mphaka atha kugwa, kuti musinthe zakudya zanu malinga ndi kusintha kwa te
