Dzino kapangidwe: anatomical subtleties zogwirizana liziyenda

The Cholinga chachikulu cha mano (monga munthu kapena nyama) kwa aliyense chinsinsi. Iwo - kukukuta chakudya (nyama komanso analanda ndi kugwira nyama). Matenda a mano ndi mawonekedwe awo ndi osiyana pang'ono malingana kugwira ntchito. Pali mitundu inayi: incisors, canines, premolars ndi molars. Anthu, woyamba mitundu iwiri kudula ntchito, ndi wotsiriza - tulo.

Kodi iwo ntchito

chiwerengero cha mano anthu - 32, ndi osiyana nyama (malingana ndi mtundu). Iwo zili mu mzere wa chapamwamba ndipo nsagwada m'munsi. dzino dongosolo kwa aliyense mafupa nsagwada onse mofanana, iwo wapangidwa ndi minofu ofanana. Aliyense wa iwo ili mu dzenje yake fupa anapanga m'munsi kapena chapamwamba chibwano, wotchedwa alveoli. Anatomically mano ali mabungwe otsatirawa: korona, khosi, muzu (chimodzi kapena kuposa). Korona - kumtunda kwa Kufikika kwambiri anayendera, projecting pamwamba chingamu lapansi. The khomo pachibelekeropo ndi yaing'ono woonda Division ili minofu zofewa makulidwe. Choncho, muzu - gawo kupita mu akuya bwino. mapeto ake nsonga ya dzino imatchedwa, thupi lake kugwa mu misempha ndi mitsempha ya magazi. Dzino kapangidwe (ngati canine kapena molar) kwambiri osati kunja mawonekedwe, komanso chiwerengero cha mizu (1 mpaka 3). Mawonekedwe wodula - athyathyathya ndipo lonse, ali ndi akadaulo. Canines yodziwika kukulitsa pang'ono, premolars ndi molars - kutafuna pamwamba ndinasintha m'goli.

Kufotokoza kapangidwe mkati mwa dzino, tisaiwale kuti zigawo minofu anakonza m'menemo. Wosanjikiza kuya - zamkati - ukufanizidwa ndi mtolo neuro-mtima. Dentin wazungulira, nthawi zina amatchedwanso fupa mano. Ndi wokongola olimba, koma akhoza kufewetsa atadziŵa tizilombo. Koma kufotokoza kapangidwe ka dzino mu wosanjikiza pamwamba, m'pofunika kuti si chomwecho pa korona ndi mizu. enamelled Choyamba (mochititsa olimba, zimene zinaphatikizapo 97 salt% mchere). Wosanjikiza kunja kwa muzu wapangidwa ndi simenti, imene, kuwonjezera pa mandimu salt ali ambiri ulusi kolajeni. Recent nsalu mu fupa, kulenga periodontal (ndiponso kuika dzino dzenje ake).

makhalidwe poyerekeza

Monga tanena dzino anthu ali ntchito zikuluzikulu ziwiri: kuchokera incisors ndi canines - kudula, mu premolars ndi molars - akupera. Mu nyama, yotsirizira awiri kuchita cholinga ofanana. Koma incisors ndi canines ndi osiyana. The ogwirira choyamba ntchito "kudula" zidutswa chakudya, mano - kupha ndipo akugwira wovulalayo. Front kudula mano a herbivores zamoyo ayenera kudula zomera, kufikira kwa chakudya. Canines kawirikawiri kwina. Ngati iwo alipobe, inu amene timapemphera chabe mwa amuna. iwo amagwiritsidwa ntchito azimenyana wina ndi mzake kwa mkazi kutsogolera sitepe (a paketi). Tosaoneka Kapangidwe ka mano, monga tafotokozazi, mu mitundu yonse ya nyama zamoyo ziri zofanana wamoyo.
