Mitundu yamano ndi iti?

Mano anu ndi amodzi mwamphamvu kwambiri m'thupi lanu. Zimapangidwa kuchokera ku mapuloteni monga collagen, ndi mchere monga calcium. Kuphatikiza pa kukuthandizani kudya ngakhale zakudya zovuta kwambiri, zimakuthandizaninso kuyankhula momveka bwino.

Akuluakulu ambiri ali ndi mano 32, otchedwa okhazikika kapena mano achiwiri:

• Zojambula 8
• Mankhwala anayi, omwe amatchedwanso cuspids
• Ma premolars 8, omwe amatchedwanso bicuspids
• Ma molars 12, kuphatikiza mano 4 anzeru

Ana ali ndi mano 20 okha, otchedwa oyambira, osakhalitsa, kapena mano amkaka. Amakhala ndi mano 10 omwewo pachibwano chapamwamba komanso chakumunsi:

• Zojambula 4
• Mankhwala awiri
• 4 molars

Ana amakonda kutaya mano awo oyambira azaka zapakati pa 6 ndi 12. Kenako amasinthidwa ndi mano osatha. Ma molars nthawi zambiri amakhala mano oyamba okhazikika omwe amabwera. Anthu ambiri amakhala ndi mano awo okhazikika ali ndi zaka 21.

Pitirizani kuwerenga kuti mudziwe zambiri zamitundu yosiyanasiyana ya mano, kuphatikiza mawonekedwe ndi magwiridwe ake.

Mfundo yofunika

Mano anu 32 ndi ofunikira poluma ndi kugaya chakudya. Mufunikiranso mano anu kuti akuthandizeni kuyankhula momveka bwino. Ngakhale mano anu ali olimba, sangakhale moyo wonse pokhapokha mukawasamalira bwino.

Kuti mano anu azikhala bwino, tsitsani ndi kutsuka pafupipafupi, ndikutsatira kuyeretsa mano miyezi isanu ndi umodzi iliyonse.
