Uphuhliso lomzimba

Kwiinyanga ezili-9 ukusuka ekukhulelwe kuze kube sekupheleni kokukhulelwa, umntwana ukhula. Abaqeshwanisi bahlula ixesha lokukhulelwa kwixesha labama-embryon and fetal. Ukuphuhliswa kombungu kunye ne-fetus yinkqubo eninzi eyinkqubo, enomdla kungekhona kuphela koogqirha, kodwa nakwabamama bokamva. Abafazi abakhulelweyo bafuna ukwazi kangangoko kunokwenzeka ukuba umntwana wabo ozayo ukhula njani.

Amanyathelo okuphuhliswa kombungu womntu

Ixesha le-embryonic lihlala malunga neveki ezili-8, lidlula kwiinqanaba eziliqela.

1. Ngosuku lokuqala ukucwiliswa kweqanda kunye nesidoda senziwa.
2. Emva koko ulandela inkqubo yokuchotshoza, ehlala iintsuku eziliqela. Ngethuba lokuphuhliswa kombungu, nganye iseli yahlula kwaye ngenxa yoko, kubizwa ngokuba yi-blastula. Kuvela kwiiseli zakhe ukuba i-trophoblast, oko kukuthi, i-placenta ezayo, kunye ne-embryoblast-umntwana ozayo-iya kubonakala ngenxa yoko.
3. Phantse iveki emva kokukhulelwa, ukuqaliswa kokuqalisa, okuza kuqhubeka malunga neentsuku ezimbini.
4. Kwiintsuku ezingama-7 ezalandelayo, i-disk germination yenziwe. Ukususela kwi-ectoderm (uluhlu lwangaphandle lwe-embryoblast), ulusu kunye nenkqubo ye-nervous iyaqala ukuphuhlisa. Ukusuka kwinqanaba elingaphantsi, okanye i-entoblast ithuthukise indlela yokugaya, indlela yokuphefumula. Phakathi kwala macala amabini i-mesoblast, leyo leyo, eyenza i-squelem, imisipha, inkqubo yokujikeleza.
5. Ukususela kwiiveki ezintathu ukuphuhliswa kwazo zonke iistim ze-embrym yoluntu iqala. Kwaye ekuqaleni kwenyanga yesithathu, iintsholongwane zonke izitho zangaphakathi zenziwe.

Ngaphezulu, i-embryo sele ibizwa ngokuba ngumntwana.

Ixesha elibalulekileyo lophuhliso lombindi

Kulo lonke ixesha lokugaya, umama okhuselekileyo kufuneka ahlawule ingqalelo kwimpilo yakhe. Emva koko, imeko yomntwana ixhomekeke ngoku. Kodwa kukho izigaba ezithile xa ibhinqa lifuna ukuqaphela.

Ngoko esinye sezigaba ezinjalo kwisigaba se-embryonic yithuba lokumiswa, okungenakwenzeka ngenani lezizathu, umzekelo:

• ngenxa yokuzilolonga umzimba, kunye nokuphakamisa izisindo;
• ngenxa yeenkqubo zokugulisa kwi-uterus;
• ngenxa yokuchasana nezinto ezinobuthi, iziyobisi, iibisiki;
• ngenxa yezifo ezithile.

Umzuzu obalulekileyo obalulekileyo obalulekileyo wokuphuhliswa kunye nokukhula kwebridi lixesha ukusuka kwiiveki ezi-5 ukuya kwezi-8. Ukususela ngelo xesha zonke izitho ezibalulekileyo zenziwa, kunye nentambo yomlomo, ngoko kuyimfuneko ukuzama ukuqinisekisa ukuba akukho miphumo enobungozi eyenziwa kwimizimba yomfazi okhulelweyo. Ngaphandle koko kunokuyingozi kakhulu imeko yempilo yeemvuthu.
