Intshayelelo: Amazinyo ezinja neekati
Izinja neekati ziphakathi kwezona zilwanyana zasekhaya zidumileyo ehlabathini. Njengezilwanyana ezitya inyama, zinamazinyo akhethekileyo alungele ukubamba nokukrazula amaxhoba azo. Kweli nqaku, siza kuphonononga i-anatomy yamazinyo enja kunye nekati, inani lamazinyo analo, umahluko, imisebenzi kunye nokhathalelo lwamazinyo.
I-anatomy yamazinyo enja
Izinja zineentlobo ezine zamazinyo: incisors, canines, premolars, kunye ne-molar. Ii-inciors zisetyenziselwa ukuluma kunye nokusika, ii-canines zokubamba kunye nokukrazula, i-premolars yokutyumza, kunye ne-molars yokugaya. Umhlathi ongasentla wenja unamazinyo angama-20 ewonke, ngelixa umhlathi ongezantsi unamazinyo angama-22.
Amazinyo ezinja anengcambu ende enika uzinzo kunye nokomelela. I-enamel, eyona maleko yangaphandle yezinyo, yeyona nto inzima emzimbeni. I-pulp, eyona nxalenye yangaphakathi yezinyo, inemithambo-luvo kunye nemithambo yegazi eyondla izinyo.
I-anatomy yamazinyo ekati
Iikati nazo zineendidi zamazinyo: incisors, canines, premolars, kunye nemolars. I-incisors isetyenziselwa ukuluma kunye nokusika, ii-canines zokubamba kunye nokukrazula, i-premolars yokutyumza, kunye ne-molars yokugaya. Nangona kunjalo, banamazinyo ambalwa kuneenja.
Umhlathi ongasentla wekati unamazinyo ali-16 xa ewonke, ngelixa umhlathi ongezantsi unamazinyo ali-14. Amazinyo ekati anesakhiwo esifanayo nezinja, ezinengcambu ende, i-enamel, kunye ne-pulp. Noko ke, ingcambu yezinyo lekati imfutshane kuneyenja, nto leyo eyenza ukuba lingazinzi.
Zingaphi izinja ezinazo izinja?
Izinja ezindala zinamazinyo angama-42 ewonke, angaphezu kweekati. Njengoko kuchaziwe ngaphambili, umhlathi ophezulu unamazinyo angama-20, kwaye umhlathi ongezantsi unamazinyo angama-22. Amantshontsho kwelinye icala, anamazinyo angama-28, athi endaweni yawo amazinyo asisigxina xa eneenyanga ezine ukuya kwezintandathu ubudala.
Zingaphi amazinyo iikati ezinazo?
Iikati ezindala zinamazinyo angama-30 ewonke, angaphantsi kwezinja. Umhlathi ongasentla unamazinyo ali-16, kwaye umhlathi ongezantsi unamazinyo ali-14. Amantshontsho ekati anamazinyo angama-26, athi endaweni yawo amazinyo asisigxina xa sele eneenyanga ezine ukuya kwezintandathu ubudala.
Umahluko phakathi kwamazinyo enja nawekati
Nangona izinja kunye neekati zineentlobo ezifanayo zamazinyo, ziyahluka ngobukhulu kunye nokumila kwazo. I-canines yezinja zide kwaye zikhombe ngakumbi kuneekati, ezenza kube ngcono ukubamba kunye nokukrazula amaxhoba. Okwangoku, ii-canines zeekati zifutshane kwaye zigobile, ezinceda ukuba zilume kwaye zibulale ixhoba lazo ngokukhawuleza.
Izinja nazo zinemolars eninzi kuneekati, nto leyo eyenza kube ngcono ekusileni ukutya. Iikati, kwelinye icala, zine-molars ezimbalwa kodwa zine-premolars ezibukhali, ezisetyenziselwa ukusika inyama yexhoba labo.
Imisebenzi yamazinyo enja nawekati
Amazinyo ezinja neekati abalulekile ukuze ziphile njengezilwanyana ezitya inyama. Zisebenzisa amazinyo azo ukuze zibambe, zibulale kwaye zitye amaxhoba azo. I-incisors isetyenziselwa ukuluma kunye nokusika, ii-canines zokubamba kunye nokukrazula, i-premolars yokutyumza, kunye ne-molars yokugaya.
Amazinyo akwadlala indima kunxibelelwano nakwindlela yokuziphatha ekuhlaleni. Ngokomzekelo, izinja zisebenzisa amazinyo azo ukubonisa ukuba ndlongondlongo, ukudlala okanye ukuzithoba. Iikati zona zisebenzisa amazinyo ukuzilungisa kunye namaqabane azo.
Indlela amazinyo akuchaphazela ngayo ukutya kwezinja kunye neekati
Amazinyo ezinja kunye neekati achaphazela ukutya kwazo ngeendlela ezininzi. Ngokomzekelo, izinja ezinamazinyo alahlekileyo okanye aphukileyo zinokuba nobunzima bokutya ukutya okunzima, okunokubangela ukungondleki. Ngokufanayo, iikati ezineengxaki zamazinyo zinokukuphepha ukutya ngokupheleleyo, oku kunokukhokelela ekulahlekeni kwesisindo kunye neminye imiba yezempilo.
Izinja kunye neekati nazo zineemfuno ezahlukeneyo zokutya. Izinja zi-omnivores, nto leyo ethetha ukuba zingatya zombini inyama kunye nokutya okusekelwe kwizityalo. Nangona kunjalo, amazinyo abo alungele ukutya inyama, nto leyo ethetha ukuba bafuna ukutya okuneprotheyini eninzi. Iikati, kwelinye icala, zii-obligate carnivores, okuthetha ukuba kufuneka zitye inyama ukuze ziphile.
Ukhathalelo lwamazinyo ezinja neekati
Ukhathalelo lwamazinyo lubalulekile kwimpilo nakwintlalontle yezinja neekati. Ukuhlanjwa rhoqo, ukuhlafuna amazinyo, nokucoca amazinyo ngobuchule kunokuthintela iingxaki zamazinyo ezinjengokwakheka kwetartar, isifo seentsini nokubola kwamazinyo.
Abanini bezilwanyana ezifuywayo kufuneka babeke iliso kwimpilo yamazinyo yesilwanyana sabo kwaye bafune ukhathalelo lwezilwanyana ukuba baqaphela naziphi na iimpawu zeengxaki zamazinyo ezifana nokuphefumla kakubi, ukuvuza, okanye ukuhlafuna ubunzima.
Iingxaki zamazinyo eziqhelekileyo kwizinja kunye neekati
Iingxaki zamazinyo zixhaphakile kwizinja kunye neekati, ngakumbi njengoko zikhula. Ezinye zeengxaki eziqhelekileyo zamazinyo ziquka:
- Izifo zePeriodontal
- Ukubola kwamazinyo
- Isifo seentsini
- Amazinyo aphukileyo okanye angekhoyo
Ezi ngxaki zinokubangela intlungu, usulelo, kunye neminye imiba yezempilo ukuba ayiphathwanga. Abanini bezilwanyana zasekhaya kufuneka bafune ukhathalelo lwezilwanyana ukuba baqaphela naziphi na iimpawu zeengxaki zamazinyo.
Ukuqukumbela: Sesiphi isilwanyana esinamazinyo amaninzi?
Ukuqukumbela, izinja zinamazinyo amaninzi kuneekati. Izinja ezindala zinamazinyo angama-42 ewonke, ngelixa iikati ezindala zinamazinyo angama-30. Nangona kunjalo, inani lamazinyo alibonisi ukuba impilo okanye ukomelela kwamazinyo esilwanyana. Ukunyamekelwa kwamazinyo rhoqo kunye nokubeka iliso kunokuthintela iingxaki zamazinyo kunye nokuqinisekisa impilo kunye nokuphila kakuhle kwezinja kunye neekati.
Iingcamango zokugqibela malunga nezinja kunye namazinyo ekati
Izinja kunye neekati zinamazinyo akhethekileyo alungele indlela yokuphila yenyama. Amazinyo azo adlala indima ebalulekileyo ebomini, ekunxibelelaneni nasekuziphatheni kwabo. Ukhathalelo lwamazinyo lubalulekile kwimpilo nakwintlalontle yezinja neekati, kwaye abanikazi bezilwanyana zasekhaya kufuneka bafune ukhathalelo lwezilwanyana ukuba baqaphela naziphi na iimpawu zeengxaki zamazinyo. Ngokukhathalela amazinyo esilwanyana sasekhaya, abanikazi bezilwanyana bangaqinisekisa ukuba abahlobo babo abanoboya baphila ubomi obonwabisayo nobunempilo.
