Ukwakheka ezinyweni womuntu kanti ezinye nezinye izitho umlomo

Muva nje, enhle izinyo isakhiwo umdwebo ingatholakala ehhovisi cishe njalo wamazinyo. On the ezimibalabala isithombe zaveza multilayer kuyinkimbinkimbi isakhiwo, njengoba izinombolo ezincane imakwe izingxenye ezihlukahlukene zomzimba. Nokho, akuwona wonke umuntu ongase akwazi ngokushesha ukuphinda wonke amazinga izinyo kanye nezici zabo zisebenza kahle. Lesi sihloko kulabo musa kakazi, futhi kulabo ungakhumbuli kahle isakhiwo ezinyweni womuntu. Ukuze ekuhlaziyeni ibhekwa isethulo idatha ku le ngalo ingaphakathi ngomlomo bebonke.

Ngakho, liyini isakhiwo emlonyeni womuntu? Yiqiniso, okokuqala lapho ucabangela lesi sifunda yokwakheka kufanele uchaze izindebe. Ziyakwazi ongavamile ku ukuthi isikhumba umngcele red akuyona ngempela esikhumbeni, futhi has a lot of izici ezifanayo kanye le mucosa. Yena wets yena ngeke bakwazi, Ngakho-ke, ngezikhathi ezithile ukhotha izindebe zakhe ngempela futhi ngokwemvelo. Kungenjalo aqhephukile. Futhi, kukhona omunye hhayi Kwakona owaziwa mayelana izihlathi - njengoba izibonelo amaseli kungaba bestravmatichno susa kubo, khona-ke asuka izingcezu esihlathini ka mucosa ukucacisa abasubathi chromosomal ubulili. Ngezinye izikhathi imiphumela emangalisayo.

Ngo ingaphakathi ezihlathini ahlelwe nezindlala encane lwamafinyila. Bona secrete a uketshezi amaprotheni. Ulimi siqukethe imisipha striated, izitho elise kwalo mouthfeel - uhlobo 3 papillae. Ngesikhathi impande yolimi imfundo ekhethekile - idlala lingual. Kuyinto uhlaka amasosha omzimba womuntu, futhi kubaluleke kakhulu ekulweni nezifo. Isakhiwo emlonyeni yomuntu okunengqondo ngokujulile.

Amazinyo ahlelwe ezimbili zezitokisi ezingu-izinsini (ngokuvamile), lapho arc engenhla kancane sibe sikhulu kunesihlalo ephansi, ngakho amazinyo aphezulu bite lesifanele kancane idlulela aphansi. Manje sitshele mayelana isakhiwo izinyo indoda. Kumiswa enkulu ingxenye izinyo is a uhlobo olukhethekile ezicutshini, lime ephelele - dentin. I projecting ngaphezu gum we izinyo limbozwa okuqinile izicubu EPITHELIAL ngokuthi koqweqwe lwawo ngokukhethekile. Le ngxenye izinyo efihlekile, embozwe olunye uhlobo kwezicubu, ngokuthi usimende.

Indawo lapho ijoyina ebusweni (umqhele) futhi kufihlwe (izimpande) we ngezinyo, ngokuthi wesibeletho. Line, ezixhunywe koqweqwe lwawo kanye usimende, yaqanjwa umugqa wesibeletho.

izinyo ngasinye siqukethe umgodi ngaphakathi, ngokuthi uginindela. indawo ebanzi kusuka phezulu izinyo yigama ekamelweni uginindela endaweni empandeni - canal impande. Kuyinto kule ndawo bamazinyo bathi, lapho ukutshelwa iziteshi uphawu. Okuqukethwe kulo mkhakha - uginindela - has a lot of yezinzwa kakhulu futhi imithambo yegazi. Kuyinto kule ndawo inikeza imisebenzi esemqoka izinyo. Isendlalelo uginindela ozungezayo amaseli akhethekile - odontoblasts. Bona ngokukhethekile ekuthuthukiseni dentin. BanjengamaJuda amaseli akha ithambo lomuntu. Ukwakheka ezinyweni womuntu ufana ngezindlela eziningi isakhiwo amathambo.

imithambo yegazi kanye nezinzwa, okuyinto banakekele ngezinyo, uyifake ngokusebenzisa aphansi foramen apical, esemgwaqweni phezulu impande ezinyweni ngamunye.

Njengoba amazinyo anamekwe ithambo? Nge Imicu yotshani okuyisipesheli aqukethe ezicutshini. Lezi izinyanda abizwa umsipha periodontal noma periodontal nje. Basuke eyakhiwa collagen ethandele, nomunye ekupheleni, afakwa ku izidakamizwa intercellular ithambo alveoli (ikhefu ekhethekile ushingamu ukuze izinyo), futhi ngakolunye uhlangothi - ku dentin izinyo.

Lapho izinyo kuqhuma inqubo, ushingamu iqinile maqondana koqweqwe lwawo, futhi umugqa wesibeletho akusho aphume ashone olubonakalayo. Kodwa izinsini abadala "ezikhoselweni" bese kuba kusabonakala dentin. Yiqiniso, lokhu kwenza amazinyo ongabantu yobudala ehloniphekayo kusengozini.

womuntu izinyo isakhiwo akunzima kakhulu, kodwa umonakalo kunoma yiliphi izinga kuyingozi. Ngakho-ke kuyadingeka ukuba bagcine zonke izinyathelo yokuhlanzeka, futhi nje ukuxubha amazinyo akho akwanele, sisenalo a Floss ekhethekile ukuhlanza izikhala phakathi kwawo.
