Ukuthuthukiswa kombungu

Kungakapheli izinyanga ezingu-9 kusukela ekukhulelwe kuze kube sekupheleni kokukhulelwa, umntwana uqala. Izifo zokuhlukumezeka zihlukanisa isikhathi sokukhulelwa esikhathini sokubambisana nesibungu. Ukuthuthukiswa kwe-embryo kanye ne-fetus kuyinkimbinkimbi yenqubo eminingi, engenasithakazelo hhayi odokotela kuphela, kodwa nakumama ozayo. Abesifazane abakhulelwe bafuna ukwazi ngangokunokwenzeka ukuthi ingane yabo yesikhathi esizayo ikhula kanjani.

Izindlela zokuthuthukiswa kombungu womuntu

Inkathi ye-embryonic ihlala cishe amasonto angu-8, idlula ngezigaba eziningana.

1. Usuku lokuqala ukukhulelwa kweqanda ne-sperm kwenzeka.
2. Bese kulandela inqubo yokuchoboza, okuhlala izinsuku eziningana. Phakathi nalesi sikhathi sokuthuthukiswa kombungu, iseli ngalinye lihlukaniswe futhi ngenxa yalokho, kubhekwa okuthiwa i-blastula. Ivela kumaseli akhe ukuthi i-trophoblast, okungukuthi, i-placenta yesikhathi esizayo, kanye ne-embryoblast-ikusasa lomntwana-izovela ngokulandelana.
3. Cishe ngesonto ngemuva kokukhulelwa, ukuqala ukuqala, okuzohlala izinsuku ezimbili.
4. Ezinsukwini ezingu-7 ezilandelayo, kukhishwa i-disc germin. Kusukela ku-ectoderm (ungqimba lwangaphandle lwe-embryoblast), isikhumba nesistimu yezinzwa kuqala ukuthuthukisa. Ukusuka engqimba engezansi, noma entoblast ithuthukise indlela yokugaya, umzila wokuphefumula. Phakathi kwalezi zigaba ezimbili yi-mesoblast, okuyinto eyenza i-squele, imisipha, isimiso sokujikeleza.
5. Ukusuka kwamasonto amathathu ukuthuthukiswa kwazo zonke izinhlelo zesibungu somuntu kuqala. Futhi ekuqaleni kwenyanga yesithathu, amagciwane azo zonke izitho zangaphakathi akhiwe.

Ngaphezu kwalokho, umbungu usuvele ubizwa ngokuthi i-fetus.

Izikhathi ezibucayi zokuthuthukiswa kombungu

Kuyo yonke isikhathi sokubeletha, umama olindelekile kudingeka anakekele ngokukhethekile impilo yakhe. Phela, isimo somntwana ngokuqondile sincike kulokhu. Kodwa kunezigaba ezithile lapho owesifazane kudingeka aqaphele.

Ngakho-ke esinye sezigaba ezinjalo esigabeni sama-embryonic yisikhathi sokufakelwa , okungeke kwenzeke ngezizathu eziningana, isibonelo:

• ngenxa yokuzivocavoca umzimba okusebenzayo, kanye nokuphakamisa izisindo;
• ngenxa yezinqubo ze-pathological in the uterus;
• ngenxa yokuchayeka izinto ezinobuthi, izidakamizwa, ubuthi;
• ngenxa yezifo ezithile.

Umzuzwana obalulekile obalulekile obalulekile wokuthuthukiswa nokukhula kombungu uyisikhathi esivela emavikini ama-5 ukuya kwangu-8. Kusukela ngaleso sikhathi zonke izitho ezibalulekile zakhiwa, kanye nethambo ye-umbilical, ngakho-ke kuyadingeka ukuzama ukuqinisekisa ukuthi akukho miphumela eyingozi emzimbeni wesifazane okhulelwe. Uma kungenjalo kungalimaza kakhulu isimo sezempilo semvuthu.
