I-Aatomical yeSayensi yeNzululwazi ye-Aatomical ye-Aatomical ye-Aatominel ye-Aatomive ye-Aatomive yeMibungu yeMidlalo yeLabhoratri yeLabhoratri

Iimodeli ezili-10 zisetwe ukubonisa ubudlelwane phakathi kwenkqubo yophuhliso ye-fetus kunye nesibeleko ku-Okthobha ukukhulelwa. Iqanda libizwa ngokuba likhulelwe okanye lichumile kwiiveki ezi-2 emva kokuchumisa; Iiveki ezi-3-8 emva kokuchumisa zibizwa ngokuba yimibungu; Ukusukela ekupheleni kweveki ye-8, ibizwa ngokuba yiFutus; Iiveki ezisi-8; I-BLOGO imalunga ne-3cm ixesha elide kwaye sele iqalisile ukuthatha ubume bomntu, ngentloko enkulu, amehlo abonakalayo, iindlebe, impumlo kunye nomlomo. Ukuqulunqwa kwentliziyo yokuqala kunye nokudunyiswa kunokufunyanwa ngovavanyo lwe-Ultrasound. Kwiiveki ezili-12, i-fetus yi-7 ~ 9cm ubude kwaye inobunzima obuyi-20g. I-Exogogous Orthogonia yenzekile, kukho imisebenzi ebuthathaka kwilungu, kunye namaziko e-ossals avele kumathambo amaninzi. Kwiiveki ezili-16, i-fetus imalunga ne-10 ukuya kwi-17cm ubude kwaye inobunzima obuyi-100 ukuya kwi-120g. Inolusu olubomvu, olugudileyo nolubonakala olubonakalayo ngenani elincinci leenwele ze-vellis. Ngaphaya kophuhliso lwethambo, uvavanyo lwe-X-Ray lunokubona isithunzi sethambo, ngaphandle kwangaphandle kunokuhlulahlula umntu nomntu obhinqileyo. Uviwo lwesisu lunokuva intliziyo evakalayo yentliziyo, abafazi abakhulelweyo banokuziva benza umlando. Kwiiveki ezingama-20, i-fetus yi-18 ~ i-27cm ubude, inobunzima obungama-300g, ulusu lunciphile, i-facpared i-1/3 yomzimba, kukho ukukhula kweenwele , kwaye umsebenzi wokuginya uqalisa. Iiveki ezingama-24 ubude bomzimba wesibeleko se-28 ~ 34cm, ubunzima be-600 ~ 300G, inqatha le-subcutaneous yaqala ukufaka, isikhumba se-winkles. Kwiiveki ezingama-28, i-fetus yi-35 ~ 38cm ubude kwaye inobunzima obuyi-100 ~ 1200g. Umzimba wonke ucekeceke, ulusu lubomvu, kukho amanqatha athambileyo emnqweni (ye-toe) ayifikeleli kumnwe (toe). Kwabafazi, iLabia Majora iqulethe iLabia Minira kunye neClitoris, nakumadoda, ama-testicles avele aye kwi-scrotum. Ngenxa yamanqatha engaphantsi kwamafutha amaninzi, i-wrinkles yobuso, njengendoda endala. Ukuba ezelwe, banokukhala, baginya, kwaye bahambisa imilenze yabo, kodwa babuthathaka kwaye bafuna ukhathalelo olukhethekileyo lokuphila. I-32-vanus i-32cm i-40cm ubude, inobunzima obuyi-1500 ~ 17G, ulusu lubomvu olubomvu, iinwele zobuso ziwile, kwaye zinokuphila emva kokhathalelo olufanelekileyo. Kwiiveki ezingama-36, i-fetus ingama-45 ~ 46cm ubude kwaye inobunzima obungama-2500g. I-subcutaneus yamafutha, i-wrinkles yobuso inyamalala, umnwe (i-toe) ifikelele kwi-Nail yomnwe (i-toe). Emva kokuzalwa, ukukhwaza kunye nokuncancisa kunethuba elihle lokusinda. I-fetus ivuthwe kwiiveki ezingama-40, kunye nobude be-50cm kunye nobunzima bama-3000 ~ 3300g. Ulusu lupinki, amanqatha aphantsi aphuhliswe kakuhle, uninzi lwe-fetus luphelile, kwaye iinwele ziyi-2 ~ 3cm ubude. Isikhonkwane somnwe sidlulile kwincam yomnwe. Intshukumo yelungu elisebenzayo, isithsaba esikhulu, ukucofa okuqinileyo. Ubude bomzimba wesibeleko kunye nobunzima obuthile ngokuthe ngcembe ngenyanga yokumitha, ukulungiselela imemori, le fomathi ilandelayo isetyenziswa ukubala: ngaphambi kweeveki ezingama-20 ubude beenyanga zokumitha (cm), emva kweeveki ezingama-20 ze Ubude bokumitha = inani leenyanga zokukhulisa × 5 (cm).
