Okubili kuyinjabulo kabili kumama. Noma kunjalo, ukukhulelwa namawele kungaba nezinombolo eziningi ngisho nezinkinga, futhi okuningi kunamanje kuncike ukuthi amawele aholela ekuhlukaneni kwe-zygote eyodwa ngesonto lesibili lokukhulelwa, noma kuzoba nokukhulelwa kwamaqanda amabili ahlukene noma ukuhlukana kwangaphambili.
Izinhlobo zamawele
Amawele amabili anezinhlobo ezine eziyinhloko ezingase zivele ngenxa yokuhlukahluka kokubili kokukhulelwa. Ukuhluka okuqala kokukhulelwa, okune-subtype eyodwa, ukukhulelwa kwama-ovules amabili ngesikhathi esisodwa. Ngenxa yalokho, iwele le-bichorial diamiotic lizalwa, elinama-chorions ahlukene kanye nama-omnions ahlukene (atholakala kuma-placentas ahlukene nakwamasaka amniotic ahlukile). Izingane ezinjalo zingaba nobulili obuhlukile kanye nokubukeka okuhlukile.
Ngaphezu kwalokho, kunenye indlela yokukhulelwa. Emzimbeni womama, isithelo esisodwa kuphela se-ovum, esakhiwa yi-spermatozoon eyodwa, kodwa ngenxa yokuhlukanisa, sakha amaqanda amabili egcwele ngesikhathi esisodwa. Kuye ngosuku olwahlukana ngalo, enye yezinhlobo ezintathu zamawele. Bangase babe ne-chorion ne-omnion ehlukile, kodwa kuphela uma ukuhlukana kwenzeka ngokoqobo emahoreni okuqala angu-48-72 ngemva kokukhulelwa. Uma ukukhulelwa kwenzeka ngemuva kwesikhathi, bangase babe nomdwebo ovamile kanye nama-omiononi ahlukene noma i-chorion evamile kanye ne-omnion evamile. Ezimweni ezimbili zokugcina, amawele abizwe ngokuthi namanje i-odnoyaytsevymi, azoba ngokobulili obufanayo futhi azofana njengamaconsi amabili amanzi, hhayi nje ngaphandle, kodwa futhi iqoqo lama-chromosomes.
Amawele e-Bihorial
Ochwepheshe bakholelwa ukuthi amawele we-biamnotic impilo yomama, kanye namawele ngokwawo, okuyinto ehlukile kunazo zonke ukuthuthukiswa kwemicimbi. Ngokuvama, kuthatha cishe u-25-30% wezinombolo zamawele. Izingane zithuthuka ngokwehlukana komunye nomunye, zidla kusuka e-placenta ehlukene, ngakho-ke zinikezwa kangcono nakho konke okudingekayo ekukhuleni nasekuthuthukisweni. Amawele anjalo ngokuvamile ane-umehluko omncane wesisindo futhi azaliswa cishe egcwele. Banezinkinga ezingezansi zokuthuthukiswa kanye nezinkinga ezimbalwa ngesikhathi sokubeletha.
Ngaphezu kwalokho, ukukhulelwa okunjalo kunengozi encane yokukhathazeka kumama. Kwezinye izimo, uma izinsana zombili zilala kahle, izazi zingavumela umama ukuba abelethe ngokwabo, ngezinye izikhathi kwenzeka ukuthi abantwana bazalwa ngisho nangokwehluka kwezinsuku ezimbalwa. Yiqiniso, izingane ezincane ezisencane ziwumthwalo omkhulu, kodwa futhi zijabulisa kakhulu. Njengomthetho, ukuzalwa kwe- double dichorial kuzuzwe njengefa, ngakho uma umama emndenini usuvele enezinama, khona-ke amathuba okuthi athatha amawele e-dichoric ayanda. Amawele e-Monochorionic angabonakala kunoma imuphi umndeni futhi athembele kuphela endleleni yokuhlukaniswa kwezinsana. Ezinye izinto azidlali lutho lapha.
Ukuze unqume ukuthi yiliphi uhlobo lomama i-dichoric noma i-monochorionic, lingenziwa kwisifundo esikhethekile, isibonelo, ngesikhathi se-biopsy ye-chorionic noma i- amniocentesis . Ku-ultrasound evamile, thola lo mbuzo
Namuhla, izazi ziyazi kahle ukuthi ziphi amawele, zinganqunywa kuchwepheshe we-ultrasound, ukuthi umama we-placenta uphindwe kabili noma ongashadile, futhi ukhulume ngokuthi izingane zikhula kanjani nokuthi zinenkinga ekukhuleni. Uma kunesidingo, umama angabelwa izidakamizwa ezikhethekile ezisekelayo, ezomsiza ukuthi akhulume kuzo zombili izingane.
