I-fetus ikhula kanjani?
Phakathi nesonto lokuqala, ngaphezulu kwezinsuku ezintathu emva kokukhulelwa, iqanda kancane kancane liqhubekela phambili emgodini wesibindi. Ngesikhathi esifanayo, kuqhutshwa izinqubo ze-fission, futhi ukuqoqwa kwamaseli amakhulu kwakha kusukela ku-zygote, kufana nebhola elima. Cishe ngemva kwezinsuku ezingu-3 ngemuva kweqanda lingesibelethweni, liya endaweni yokunamathiselwe. Ngenxa yalokho, kuvela ukuthi inqubo ebalulekile njengokufakelwa kwemvelo kwenzeka ngosuku lwama-7 emva komhlangano wamaseli wesilisa nabesilisa abesilisa nabesifazane (okungenani 10). Kungenxa yokufakelwa ukuthi inqubo yokukhulelwa iqala.
Sekuvele ngesonto lesibili, i -gonadotropin ye-chorionic iqala ukhiqizwa yi- embryo, into eyenziwa ngama-hormonal eyenza isignali emzimbeni wesifazane ngokuhlelwa kabusha, ngokuphathelene nokuqala kokubeletha.
Ngamanje, ukunikezwa kwezakhi ezakhiwa iqanda kwakuphelile, ngakho-ke uthola umbungu kusuka emzimbeni womama. Lokhu kwenziwa ngamaqembu angaphandle amaseli, ama-naps.
Ngesikhathi esifanayo, ukwakheka okunjalo okwakhiwa kwe-anatomical njengoba i-placenta iqala.
Emasontweni amathathu ikusasa ingane isivele isamukela izakhi ngomzimba wegazi. Kulesi sigaba, ukuhlukaniswa kwamangqamuzana emagqabulini okuthiwa ama-embryonic okwenza izicubu, izitho nezinhlelo zenyama encane kubonakala ngokucacile.
Kukhona ibhukimakhi ye-chord - eyandulela ikholomu yomgogodla, imithwalo yegazi ivela. Ekupheleni kwesonto, inhliziyo iqala ukushaya, manje iyishubhu encane, ikhiqiza ukunyakaza kwezinkontileka, okuyinto ekuthuthukiseni iguqulwa ibe yinhliziyo engamakamelo amane.
Iviki eledlule lwenyanga yokuqala yokukhulelwa kubonakala ngokubonakala komntwana wezinkuni zamehlo, ama-pencil of emapeni nemilenze esizayo. Ngaphandle, i-embryo ibukeka sengathi i-auricle, ejikelezwe ukuqoqwa okuncane ketshezi. Akuyona into ngaphandle kwe-amniotic fluid. Ngalesi sikhathi, inqubo yokubeka izitho zangaphakathi iqala: isibindi, amathumbu, izinso, uhlelo lwe-urinary. Ngesikhathi esifanayo, ubukhulu bombungu ngokwawo bubuncane kakhulu. Ngokwesilinganiso, ngalesi sikhathi asidluli ku-4 mm.
Umama wesikhathi esizayo uzizwa kanjani?
Isisu asitholakali ngenyanga yokuqala yokukhulelwa, futhi kubonakala sengathi kuvamile, ngoba ezungezile, ngezinye izikhathi umama ngokwakhe, akazi lutho ngesimo sabo. Njengomthetho, uyayibona ngesikhathi sokubambezeleka, okubonakala emva kwamasonto angama-2-2,5 kusukela ngesikhathi sokukhulelwa.
Isibeletho ngenyanga yokuqala yokukhulelwa, ngokuphambene nalokho, siqala ukwanda ngokweqile, siyancipha, siba buhlungu. Konke lokhu kuxhunyaniswe nokuhlelwa kabusha kwe-hormonal komzimba womama owaqala emzimbeni.
Ukunikezwa ngenyanga yokuqala yokukhulelwa ngokuvamile kuvamile, ungrowth. Kulezo zimo lapho kunegazi, elihambisana nokuhlupheka esiswini esingaphansi, kubalulekile ukubonana nodokotela. Kumele uqaphele ukuthi abanye besifazane bangakwazi ukuphawula ekuqaleni kwenyanga eyi-1 isabelo segazi esingavunyelwe, esanyamalala ngemuva kosuku. Lokhu akulutho kodwa umphumela wokufakelwa.
Igazi lomama olindelwe ngenyanga yokuqala yokukhulelwa libuye lenze izinguquko. Ukuhlushwa kwe-hormone hCG kwanda ngokushesha, ngakho ekupheleni kwenyanga ukuhlola kubonisa 2 amaqembu akhanyayo, acacile ngokucacile.
Ngokuhamba kwesikhathi, lo wesifazane uyaqala ukuzwa ukukhulelwa okuzayo: ukuhlukumeza, ukucasula, ubuhlungu esifubeni, ukwanda kwamanzi, - lokhu kuyinto encane nje lapho wonke umama ozayo azobhekana nayo.
