Isikhupha sesikhupha isakhiwo esifana nesikhwama leso inesibopho sokuhambisa izakhamzimba kumbungu ngesikhathi sokukhulelwa. Akufanele siyididanise nesaka lokukhulelwa. Yize bobabili benesibopho sokuhlinzeka izakhi ngokulinganayo, isikhuphasha sizoyeka ukunikeza imisebenzi yaso kuze kube yilapho i-placenta ikhule ngokugcwele ngakho-ke izonyamalala.
Isikhwama se-yolk ivela ngaphakathi kwesikhwama sokukhulelwa futhi ayiqali ukubonwa kuze kube yisonto lesi-5 lokukhulelwa. Kuboniswe ngomumo oyindilinga omnyama futhi ingabonakala nge-ultrasound yangasese. Kubaluleke kakhulu ukuzama ukubona ngeso lengqondo ukwakheka kwayo njengoba udokotela wezifo zabesifazane ezonquma ukuthi ngabe ukukhulelwa kuhamba kahle yini.
Siyini isikhwama se-yolk?
Kuyisijobelelo esiyimbumba esihlanganiswe nombungu. Yakheke njengesaka eliyisiyingi futhi inesimo esimnyama, lapho singakuthola khona ngaphakathi kwesikhwama sokukhulelwa. Itholakala ngokunembile ixhunywe ekuvuleni kwenkaba emathunjini ombungu.
Lesi sakhiwo kungabonakala kahle ku-ultrasound futhi lapho kudingwa ngudokotela. Uma ibonakala futhi inesimo esiningiliziwe, kuzokhombisa ukuthi ukukhulelwa kuqhubeka ngokujwayelekile. Izokhula cishe ngo-1mm ngeviki kuze kufike ku-6 noma ku-7mm.
Ludlala indima enjani?
Umsebenzi wawo kuzoba uku hlinzeka ngomsoco nomoya-mpilo odingekayo ukuze umbungu ukhule. Kepha awunawo lowo msebenzi kuphela, kepha uzokhiqiza amangqamuzana egazi ukuze i-placenta yakheke ngokuphelele.
Umsebenzi wakho wesikole omningi uzoba uku ukuqeda imfucuza ekhiqizwayo (kufaka phakathi isikhutha), kuze kwakheke i-placenta futhi uzophatha ukudala amaseli ezocansi (ama-gametes). Lawa maseli azothuthela maqondana nama-gonads okuqala ombungu ukuze izitho zawo zocansi zikhule.
Kungakho ayihlali sonke isikhathi sokukhulelwa. Ngase-trimester yokuqala, i-life sac izonyamalala, ngoba izoqeda ukufeza le misebenzi ngakho-ke ngeke isabonakala nganoma yiluphi uhlobo lwe-ultrasound. Cishe isonto le-13 yilapho lizonyamalala ngokuphelele futhi yonke imisebenzi yayo izothathelwa indawo yi-placenta.
Izinhlobo zamasaka e-yolk:
- Echogenic isikhuphasha sac: yilapho ingabonakala kahle ngaphambi kwe-ultrasound.
- Isikhuphasha esingajwayelekile: Kulapho ingenaso isimo esejwayelekile futhi ikhombisa ukuthi umbungu kungenzeka awukhuli kahle, yingakho isisu singenzeka.
- Isikhwama se-yolc esibekiwe: kulapho kunokubalwa ngakho-ke ukufa kwe-intrauterine kwenzeke.
Ngokuya ngohlobo lwayo, kungatholakala uhlobo lokukhulelwa
Ukuma nobukhulu bayo ngokusebenzisa i-ultrasound bazosinika izinkomba ezidingekayo ukunquma ukuthi umbungu uqhuba kanjani inkambo yawo. Ukukhipha isisu kungenzeka uma ngemuva kweviki lesihlanu lokukhulelwa isaka lingafinyeleli kububanzi obungu-3mm. Kungenzeka futhi uma isaka likhulu kuno-9mm, futhi noma lifinyelela ku-15mm linokumila okweqile futhi umbungu awubonakali.
Okunye ukukhubazeka ukuthi isikhwama sokukhulelwa kanye ne-yolk sac ayixhunywanga esibelethweni futhi phezulu. Uma kuyicala lokuba engxenyeni engezansi, lokho sekuvele kungubufakazi bokuthi ukukhulelwa akufinyeleli ekugcineni. Uma kubhekwa amasaka ama-yolk amabili ngesikhathi se-ultrasound, kuzokhombisa ukuthi ukukhulelwa kuningi.
