Umntwana ukhula njani?
Kubalulekile ukuba uqaphele ukuba kwiinkcenkceshi kukho iziqulatho ezi-2: i- embryonic kunye ne-obstetric term. Ookuqala uvela ekukhulelwe, okwesibini ngowusuku lokuqala lwenyanga. Ngoko ke, kukho ukumahluko kweeveki ezimbini phakathi kwabo (ngokwemyinge).
Iqanda lezityalo kwiiveki ezi-4 ukususela ekukhulelweni lincinci, kwaye ubukhulu bayo abugqithanga u-5-7 mm ububanzi. Ukuba sithetha ngomntwana wexesha elizayo, ngoko ngeli xesha lingaphantsi, kuphela 2-3 mm.
Kwiiveki ezi-4 ukususela ekukhulelwe, i-embryo inokuhlukaniswa kwezicubu ezizayo. Ngeli xesha, kukho amaqabunga amathathu e-embryonic.
Uluhlu lwangaphandle - i-ectoderm, lunikeza, okokuqala, kwinkqubo yeentlungu zeza kusasa. Umgangatho ophakathi ngowama-mesoderm, kuthatha inxaxheba ebonakalayo ekubunjweni kwamathambo e-fetal, tiscues, kunye negazi.
I-Endoderm, ngokukhawuleza, ibe yinto ephakathi, iququzelele iinkqubo ezizimeleyo zezitho, izakhiwo ze-anatomical ezahlukeneyo. Umntwana ozayo emva kweveki ezi-4 ukususela ekukhulelwe sele sele ene-embryo yesimo senhliziyo. Njengoko iqhubela intliziyo ye-tube. Ukulungiswa kweentlawulo zayo kunokwenzeka ngoncedo lomshini we-ultrasound ngeli xesha.
Ngokwahlukileyo kuyimfuneko ukuthetha malunga nesakhiwo esibaluleke kakhulu se-anatomical njengepentecenta. Kule ngongoma ukuba iqalo layo liqala. Khumbula ukuba ukuvuthwa kokugqibela kubonwa kuphela ngeveki ye-20.
Umama ozayo uza kuziva njani?
Kwiimeko ezininzi, ngeli xesha umfazi ufumanisa imeko yakhe. Uvavanyo olwenziwa ngexesha elinjalo lubonisa umphumo omuhle.
Eli bhinqa lichaza ukubonakaliswa kweempawu zokuqala zokukhulelwa: ukukhubeka, ukuguquka kwemizwelo, ukuxakeka, isisulu sokuncwina ekuseni.
