Amphaka ndi agalu a abwenzi ambiri samaleredwa kuyambira ubwana, ndiye ndikufuna kudziwa kuti ali ndi zaka zingati? Kodi ndikudya chakudya cha ana amphaka ndi agalu? Kapena kudya chakudya cha galu wamkulu ndi mphaka? Ngakhale mutagula chiweto kuyambira muli mwana, mudzafuna kudziwa zaka zingati. Kodi ndi miyezi iwiri kapena itatu? Mzipatala, nthawi zambiri timadziwa zaka za ziweto kudzera m'mano.

Pali kusiyana kwakukulu pakati pa mano chifukwa cha zakudya zosiyanasiyana ndi zizolowezi zodyetsera, kugwiritsidwa ntchito kosiyana kwa zidole zokukuta mano ndi zokhwasula-khwasula, choncho nthawi zambiri, mano adzakhala olondola kwa ana agalu ndi amphaka, pamene kupatuka kungakhale kwakukulu kwa akuluakulu. agalu. Zoonadi, zomwe zimatchedwa kupatuka zimakhalanso zapakatikati. Galu wazaka 5 amadya mafupa nthawi zonse, ndipo dzino limakhala lofanana ndi la galu wazaka 10. Koma simungakumane ndi galu wazaka 10 wokhala ndi mano ofanana ndi galu wazaka zisanu. M'mbuyomu, ndinakumana ndi mwini ziweto yemwe anabweretsa tsitsi lagolide lotchedwa 17 zaka. Ndicho chinthu chachikulu. Imafunika kudziwa zaka ndi thupi lake isanayambe kulandira chithandizo. Akuti ali ndi zaka 7 mukatsegula pakamwa kuti muwone mano. Kodi n’kulakwa kukumbukira zaka za agogo ake?

Inde, mukakhala achichepere, mutha kudziwanso matenda ambiri a ziweto powona mano awo, monga ngati alibe kashiamu komanso ali ndi mizere iwiri ya mano. Choncho ndikofunika kuphunzira momwe mungayang'anire chitukuko cha mano ndikuweruza zaka ndi thanzi lawo.

Galu amayamba kukula mano 19-20 patatha masiku kubadwa; Pa masabata 4-5, ma incisors a m'mawere oyambirira ndi achiwiri ndi ofanana (ma incisors); Pamene masabata 5-6, incisor yachitatu imakhala yofanana; Kwa ana agalu a masabata 8, ma incisors amakula bwino, ndipo mano otsekemera amakhala oyera ndi owonda komanso akuthwa;

M'miyezi 2-4 ya kubadwa, ana agalu anayamba kusintha pang'onopang'ono mano odula, ndipo choyambira choyamba chinayamba kugwa ndikukula ma incisors atsopano; Wachiwiri ndi wachitatu incisors ndi canines m'malo ali ndi zaka 5-6 miyezi; Ali ndi miyezi 8 mpaka miyezi 12, mano onse amasinthidwa ndi mano okhazikika (mano osatha). Mano okhazikika ndi oyera komanso owala, ndipo incisors amakhala ndi zotuluka zakuthwa. Ngati pali chikasu, zikutanthauza kuti pali tartar;

Pamene galu ali ndi zaka 1.5-2, nsonga yaikulu ya mandibular incisor yoyamba (incisor) yatha, ndipo imakhala ndi nsonga yaing'ono, yomwe imatchedwa kuti nsonga zowonongeka; Ali ndi zaka 2.5, chikhomo chachiwiri cha mandibular incisor (dzino lapakati) chinatha; Ali ndi zaka 3.5, nsonga ya maxillary incisor inatha; Ali ndi zaka 4.5, chikhomo cha dzino lapakati pa maxillary chinatha; Awa ndi mapeto a unyamata wa galu. Kusintha kwa dzino panthawiyi sikukhudzidwa kwambiri ndi msinkhu kusiyana ndi chakudya, kotero iwo pang'onopang'ono amakhala olakwika.

Popeza galuyo anali ndi zaka 5, incisor yachitatu ya mphumi ya m'munsi ndi canine cusp anali atavala pang'ono (osati flattened), ndipo incisors woyamba ndi wachiwiri anali amakona anayi; Ali ndi zaka 6, chikhomo chachitatu cha maxillary incisor chinali chovala pang'ono, ndipo mano a canine anali osasunthika komanso ozungulira; Ali ndi zaka 7, mandibular incisors agalu akuluakulu ankavala muzu, ndipo malo opera anali ozungulira; Ali ndi zaka 8, mandibular incisors agalu akuluakulu amavala ndipo amapita patsogolo; Pa zaka 10, kuvala pamwamba pa mandibular chachiwiri incisor ndi maxillary incisor anali longitudinal ellipse; Agalu akulu nthawi zambiri amakhala zaka 10-12, ndipo nthawi zambiri mano amakhala osagwa, zomwe nthawi zambiri zimakhala zovuta;

Galu wamng’ono akakhala ndi zaka 16 amakhala ndi moyo wautali, kapena ndi galu wokalamba. Ma incisors amagwa, mano a canine sakwanira, ndipo omwe amadziwika kwambiri ndi mano achikasu osagwirizana; Ndili ndi zaka 20, mano a canine adagwa, ndipo mkamwa munalibe mano.

Poyerekeza ndi agalu nthawi zambiri amaluma zinthu zolimba kuti akukuta mano, zomwe zimapangitsa kuti zikhale zovuta kuweruza zaka chifukwa cha kutha kwa mano. Mano amphaka amakula nthawi zonse ndipo amatha kugwiritsidwa ntchito ngati njira yabwino yowonera zaka.

Mano a canine amphaka ndi aatali, amphamvu komanso akuthwa. Mano a canine ali ndi muzu wa dzino ndi nsonga ya dzino. Pamene patsekeke pakamwa kutsekedwa, mano chapamwamba agalu amakhala pa posterolateral mbali ya m`munsi mano canine. Pali kusiyana kumbuyo kwa dzino la canine. Premolar yoyamba ndi yaying'ono, yachiwiri ya premolar ndi yayikulu, ndipo yachitatu ndi yayikulu kwambiri. Ma premolars apamwamba ndi apansi onse amapangidwa ndi nsonga zinayi za mano. Dzino lapakati ndi lalikulu, lakuthwa, ndipo limakhala ndi zotsatira zong'amba thupi, choncho limatchedwanso dzino logawanika.

The mphaka amakula mawere ake oyamba incisor 2-3 milungu kubadwa; Chachiwiri ndi chachitatu incisors ndi canines amapangidwa mozungulira 3-4;

Amphaka amakula ndi incisors yoyamba ndi yachiwiri kuti alowe m'malo mwa incisors m'mawere pafupifupi miyezi 3.5-4; Ali ndi zaka 4-4.5 miyezi, incisor yachitatu imakula m'malo mwa incisor ya m'mawere; Mano a canine amakula m'miyezi isanu kuti alowe m'malo mwa mano a canine;

The mphaka kukula mano premolar pafupifupi 2 miyezi; Wachiwiri ndi wachitatu deciduous premolars amakula pa miyezi 4-6, ndipo pang'onopang'ono m'malo premolars okhazikika; Mphuno yoyamba ya posterior imakula pa miyezi 4-5. Waukulu dzino m`malo zaka amphaka ndi za 4-6 miyezi. Panthawi imeneyi, amatha kutaya chilakolako chifukwa cha dzino likundiwawa.

Mphaka ikatha chaka chimodzi, incisors yake yapansi imayamba kuvala; Pambuyo pa zaka 7, mano a canine anayamba kukalamba pang'onopang'ono, ndipo ma incisors a mandibular anakhala ozungulira; Pambuyo pa zaka 10, mano akutsogolo a nsagwada zakumtunda za mphaka amatha kugwa, kotero mutha kusintha zakudya zanu molingana ndi kusintha kwa thupi.
