Ngesikhathi esifanayo, zangaphandle azifani nalolu hlobo lwezinto ezibonakalayo phakathi kokukhulelwa. Kuze kube manje, lezi ziyi-bulges ezincane kuphela ezivela kumaqembu athile amangqamuzana.
Yini ingane ezayo ebonakalayo evikini lesithathu lokukhulelwa emva kokukhulelwa?
Ngokuvamile, kubonakala sengathi i-concha encane yezindlebe, okuyilapho inani elincane lamanzi likhona. Lokhu kwamanzi amniotic, okwenyuka esikhathini, ivolumu yayo ekhula.
Ubukhulu bombungu manje abudluli ku-1.5-2 mm. Kungenziwa kuhlolwe kuphela ngosizo lomshini we-ultrasound onesinqumo esiphezulu.
Kwenzekani ngesikhathi esifushane kangaka?
Phakathi namasonto amathathu, i-embryo inemifantu yokuphefumula, ebukeka ibhedu kakhulu. Kodwa-ke, bona ngokwabo yizifo zesikhathi esizayo sokuphefumula komntwana.
Ngesikhathi esifanayo, iqembu elihlukile lamaseli lihlukanisa, lapho isimiso sezinzwa semivuthu siqala ukwakha ngemva kwesikhashana. Esikhathini esifanayo ngesikhathi esifanayo, izintambo ze-spinal cord kanye nobuchopho zakhiwa.
Ekupheleni kwekhanda, i-eye fossa iqala ukwakha, amehlo omntwana wengomuso. Zisezincane kangangokuthi zingabhekwa ngokuphakama okuphezulu. Noma kunjalo, umbala, ukusika sekuvele kuchaziwe, ngoba lokhu kwenzeka ngisho nangesikhathi sokuhlanganiswa kwamaseli wesondo.
Qala ukuvela izinhlaka zamalungu, okuzokwakha uhlelo lwe-endocrine yengane esikhathini esizayo. Le-pancreas ne-gland yegciwane. Emasontweni amathathu kusukela ekukhulelwe, amangqamuzana egazi lokuqala avela embungwini. Yilabo okuthiwa ama-precursor of amaseli egazi, i-erythrocytes. Kakade ngosuku lwama-19, ithubhu yenhliziyo iqala ukuzisika. Inhliziyo ikhiwa kuyo ngokuqondile ngokuphelela.
Yimiphi izinguquko umama ozayo ophawulayo?
Lesi sikhathi ncamashi lapho abesifazane abaningi bezwa ngesimo sabo esithakazelisayo. Izinga likaHCG esontweni lesithathu lokukhulelwa kusukela ekukhulelweni lifinyelela kulezo zimiso ezanele ukuxilongwa. Ezimweni eziningi, ngisho nokuhlolwa okusheshayo okusheshayo kunika umphumela omuhle. Ngokuvamile, ukuhlushwa kwe-hCG ngalesi sikhathi cishe ku-1100-31500 mIU / ml. Kumele uqaphele ukuthi le parameter yedwa ayikwazi ukuphatha inani lokuhlonza, futhi ithathwa kuphela njengenkomba. Ngakho-ke, ukungafani ekuhloliseni ihomoni kudinga isifundo sesibili, kuyilapho siqinisekisa umphumela - ukuhlolwa okwengeziwe.
