Owesifazane, njengombuso, ufunda ngokukhulelwa kwakhe emasontweni amabili, uma engena esikhathini. Qinisekisa noma uphike izinsolo zokukhulelwa kungenziwa nge-test ekhethekile, ukuzwela ukwanda kwe-gonadotropin ye-chorionic emcinini (ku-hCh egazini kungathathwa kuphela kuma laboratories akhethekile emtholampilo nokuxilonga). Ngeviki lesi-5 lokukhulelwa, umbungu usuvele uthuthele emgodini we-uterine, amangqamuzana ayo aqhubeka nokuhlanganyela ngenkuthalo futhi ahlukanise. Ake sikhulume ngezici zenkambo yokukhulelwa emavikini amahlanu, kanye nokuthuthukiswa nobukhulu be-fetus.
Amasonto amahlanu ukukhulelwa - ukuthuthukiswa nobukhulu be-fetus
Ngeviki lesihlanu lokukhulelwa, i-fetus ifana ne-cylinder oblong. Ubukhulu be-fetus evikini lesi-5 lokukhulelwa kuvame ukuba yi-1.5-2.5 mm. Amaseli asevele ehlukanisiwe, hhayi ikhanda, ikhanda nezinyawo ziphela ziqala ukuhluka, izindawo zokwakhiwa kwezimbambo nemilenze (ama-edge of the upper and lower extremities anqunywa), isisu nomhlane. Umcimbi obalulekile ekuthuthukiseni ukukhulelwa emasontweni amahlanu kungukuqala kokubunjwa kwenhliziyo nemithambo yegazi emikhulu kanye nezitho zokuphefumula (amaphaphu kanye ne-trachea). Ekupheleni kweviki lesihlanu ukusika kokuqala kwenhliziyo kubhalwe.
Ebuswini emasontweni angu-4-5 kukhona ukwakheka okusebenzayo kwebhubhisi ye-neural, lapho umgogodla nomgogodla uyobe usuqala khona. Ukuphela komgogodla we-neural tube kancane kancane futhi kwakha ukwakheka kwengqondo. Ngesikhathi se-neural tube, okuthiwa ama-somites akhiwa, okuyizinto eziyinkimbinkimbi yezicubu zomzimba. Ngeviki lesi-5 lokuthuthukiswa kombungu, ukubunjwa kwesibindi nama-pancreas akhiwa.
I-embryo evikini le-5 yentuthuko ikhona esikhwameni se-yolk, ubukhulu obuyi-1 cm, kanti ubukhulu be-fetus abukho ngaphezu kwe-2.5 mm. I-yolk sac yizigaba ezimbili zokuzivikela, phakathi kokukhiqizwa kwezakhi kanye namaseli abomvu obomvu okwakhiwa.
I-fetal ultrasound ngesonto 5
I-Ultrasound iyindlela enembile kakhulu futhi yesimanje, ikuvumela ukuba ubone ukuthuthukiswa kwe-fetus emavikini angu-5-6. Kuleli gama, i-ultrasound yenziwa kuphela ezimweni lapho udokotela exwayisa into ethile, akuyona ukuhlola.
Ngeviki le-5 lokukhulelwa, i-ultrasound inga:
- anqume isikhathi sokubeletha kanye nenani lemibungu emgodini we-uterine;
- hlola okunamathiselwe kombungu, ikhanda nezinyawo ziphela;
- ukukala usayizi we-coccyx-parietal we-fetus - i- CTE ye-fetus inqunywa ngokulinganisa ibanga ukusuka komqhele kuya ku-coccy emavikini angu-5, ubukhulu bayo buzoba yi-1.5-2 mm;
- I-Ultrasound emavikini angu-5 inganquma isongo esivele sikhona sokukhipha isisu.
Imizwa yowesifazane evikini lesi-5 lokukhulelwa
Ngesonto lesi-5 lokukhulelwa, owesifazane angase aqale ukuzizwa ukubonakaliswa kokuqala kwe-toxicosis : isicashu, ukuhlanza, ukunxusa ukudla noma ukushintsha imikhuba yokudla (kungase kufuneke usawoti noma ubumnandi), ukulala, ukuthukuthela, ubuthakathaka (okuvame ukuhambisana nomfutho wegazi ophansi). Isibalo somama esizayo asishintshe okwamanje,
Izinguquko emzimbeni wesifazane, ukubonakaliswa okubonakalayo kwe-toxicosis kuhlotshaniswa noshintsho emlandweni we-hormonal - ukwanda okwenziwe kwe-progesterone ngomzimba ophuzi wokukhulelwa. Iviki eli-5 lokukhulelwa ingenye yezikhathi ezibucayi lapho owesifazane kudingeka azivikele ezicini eziyingozi (ukutheleleka kwegciwane, ukubhema ugwayi kanye nophuzo), njengoba kungaphazamisa ukwakheka kwezitho zesisu kanye nezinhlelo.
