Umfazi, njengomgaqo, ufunda ngokukhulelwa kwakhe kwiiveki ezingama-2-3, xa engenayo ukuya esikhathini. Qinisekisa okanye ukhanyele uxolo lokukhulelwa lunokwenziwa ngolu vavanyo olukhethekileyo, oluvakalayo ukwandisa kwi-chorionic gonadotropin emcinini (kwi-hCh egazini inokumiselwa kuphela kwii-laboratories ezizodwa kunye neengcali zokuxilonga). Kwiveki yesi-5 yokukhulelwa, i-embryo sele isishenxise kwisigxina se-uterine, iiseli zayo ziyaqhubeka nokuhlanganyela ngokuzimeleyo kwaye zahluke. Masithethe ngeempawu zendlela yokukhulelwa kwiiveki ezi-5, kunye nophuhliso kunye nobukhulu bomntwana.
Iiveki ezingama-5 zokukhula-uphuhliso kunye nobukhulu bomntwana
Ngeveki yesihlanu yokukhulelwa, umntwana ufana ne-cylinder oblong. Ubungakanani bentsholongwane kwiveki yesi-5 yokukhulelwa kuvame ukuba yi-1.5-2.5 mm. Iiseli sele zidibene ngokwahlukileyo, intloko kunye neenyawo ziphela ziqala ukuhluka, indawo zokubunjwa kweempahla kunye nemilenze (iindawo eziphezulu kunye nezantsi ezisezantsi zizimisele), isisu kunye nomva. Isiganeko esibalulekileyo ekuphuculweni komntwana kwiiveki ezi-5 kukuqala kokubunjwa kwentliziyo kunye nemithambo yegazi emikhulu kunye nezitho zokuphefumula (imiphunga kunye ne-trachea). Ekupheleni kweveki yesihlanu ukucinywa kokuqala kwentliziyo kubhalwe.
Kwi-intsuku ezi-4 ukuya ku-5 kukho umthamo osebenzayo webhubhu ye-neural, apho umgudu nomgudu womgogodla uya kwakha. Ukuphela kwesigxina se-neural tube kuya kwandula kwaye kubangela ukubunjwa kwengqondo. Kwindlela ye-tube ye-neural, okubizwa ngokuba yi-somites yenziwe, eyona yimizimba yamathambo. Kwiveki yesi-5 yokuphuhliswa kwembungu, i-rudiments yesibindi kunye ne-pancreas zenziwe.
I-embryo kwiveki yesi-5 yentuthuko i-yolk sac, ubukhulu bayo buyi-1 cm, kwaye ubukhulu bomntwana abuyi ngaphezu kwe-2.5 mm. I-yolk sac i-2 yolondolozo, phakathi kweyiphi imveliso yezondlo kunye neeseli ezibomvu zegazi ezibumba.
I-fetal ultrasound ngeveki 5
I-Ultrasound yindlela echanekileyo kunye neyobuhla, ukuvumela ukuba ubone ukuphuhliswa komntwana kwiintsuku ezi-5-6. Kulo thuba, i-ultrasound iyenziwa kuphela kwiimeko xa ugqirha ekwazisa into ethile, akuyiyo ukuhlola.
Kwiveki yesi-5 yokukhulelwa, i-ultrasound inakho:
- ukugqiba ixesha lokugaya kunye nenani leembrusi kwisigxina se-uterine;
- ukuvavanya isinamathiselo sembungu, ikhanda nentloko iphelile;
- ukulinganisa ubungakanani be-coccyx-parietal yomntwana - i- CTE yemfusu imiselwe ngokulinganisa umgama ukusuka kwithsaba ukuya kwi-coccy kwiiveki ezi-5, ubukhulu bayo bube yi-1.5-2 mm;
- I-ultrasound kwiiveki ezi-5 kunokunquma isongelo esasikhona sokukhupha isisu.
Imiva yowesifazane kwiveki yesi-5 yokukhulelwa
Kwiveki yesi-5 yokukhulelwa, umfazi angakwazi ukuqala ukubonakaliswa kokuqala kwe-toxicosis : isicongconi, ukuhlanza, ukunxilisa ukutya okanye ukutshintsha iindlela zokutya (unokufunwa usawoti okanye ubumnandi), ukulala, ukugwenxa, ubuthathaka (ngokuqhelekileyo kudibene nokuxinzelelo lwegazi). Isibalo somama esizayo asizange sitshintshe,
Utshintsho kumzimba womfazi, ukubonakaliswa kwe-toxicosis kunokubakho ukutshintshwa kwimiba ye-hormonal - ukwanda kweprogesterone ngomzimba ophuzi wokukhulelwa. Iiveki ezi-5 zokukhulelwa ngenye yezona zihlandlo ezibucayi xa ibhinqa lifuna ukuzikhusela kwiimeko ezinobungozi (ukusuleleka kwintsholongwane, ukutshaya utshayi notywala), njengoko kunokuphazamisa ukubunjwa kwamalungu omzimba kunye neenkqubo.
