Iviki leshumi nambili lokukhulelwa libhekene nokunciphisa ukukhula komntwana. Kusukela kule nkathi, ukuphakama kwakhe kuzolinganiswa kusukela kumqhele kuya ezithende, kanti ngaphambi kokuba kwenziwe kusukela emqhele kuya komsila. Manje isisindo esingu-380 amagremu futhi sinokuphakama okungaba ngu-26.7 cm. Lezi idatha ezilinganiselwe, futhi zingashintsha kancane kuye ngezici ezithile. Imilenze yengane iyanweba, futhi umzimba wakhe uthatha isilinganiso esifanele. Ukunyakaza kwe-Fetal emavikini angu-21 kuba okubonakala kakhudlwana, futhi kungabhekwa umama kuphela, kodwa futhi nezihlobo.
Ngalesi sikhathi ingane isivele idala ama-eyelashes, amashiya. Angakwazi ukukhanya. Uma isisu sesinebulili besilisa, ama-testicles asevele adlulile, futhi emasontweni ambalwa azothola emgodini we-pelvic abe yi-scrotum.
Kusukela ngesonto lama-21 lokuthuthukiswa komntwana, usengakuthola kakade. Ungafunda izincwadi kuye noma ufake umculo othulile. Ngale ndlela uzolungisa izintandokazi zomculo wengane yakho. I-fetus esontweni lama-21 yokukhulelwa iqala ukuzwa ukunambitheka kokudla okudliwe ngumama. Lokhu kwenzeka ngokugwinya amniotic fluid . Ngakho-ke, kusukela manje usungakha izintandokazi zokunambitheka kwengane.
Norm of anatomy fetomy ngesonto 21
Ukuthuthukiswa kwe-fetus emavikini angu-20-21 kuhlolwa yi-ultrasound. Imingcele ye-fetus ngesonto 21 imvumela ukuba ahambe ngokukhululekile ngaphakathi kunina futhi angabonwa ngokugcwele. Kulesi sigaba sokuthuthukiswa kubalulekile ukunquma imingcele yesilinganiso senhliziyo yentombazane, umsebenzi wokwakha, ubukhulu bomzali, ubude be-hip, isisindo somzimba, ububanzi besifuba, ubukhona nokuthuthukiswa kwezakhiwo zobuchopho.
I-fetometry ye-fetus ngesonto lama-21 kufanele ibe nalokhu okulandelayo
- ubukhulu bekhanda bomzali kule nkathi buvela kumashumi amane nesithupha kuya kwamamitha amahlanu namashumi ayisithupha;
- usayizi we-frontal-occipital uphakathi kwamashumi ayisithupha kuya kwamashumi ayisithupha nambili;
- ikhanda eliyihloko - 166 - 200 mm;
- umjikelezo we-fetus ungama-144 - 187 mm.
Phakathi nalesi sikhathi, isisu se-fetus sinqunywa, ukuba khona kwezitho zangaphakathi, isakhiwo sobuso kanye namasipha. Manje ubonakala enomzimba omncane, futhi umsebenzi wakhe oyinhloko ukuthuthukisa imisipha nokuqoqa amafutha. Ukuze wenze lokhu, umama olindelekile kufanele adle ngokugcwele.
