Ingane isithelo sothando lomuntu nowesifazane, futhi kuyamangalisa ukuthi amangqamuzana amabili ezocansi ahlangene, aphindwe, ashintshe futhi aphenduke isimangaliso esikhulu kunazo zonke emhlabeni. Umama ngamunye unesithakazelo ekuthuthukiseni i-intrauterine yomuntu ophethe ngaphansi kwenhliziyo yakhe.
Izikhathi zokuthuthukiswa kwe-intrauterine
Kunezinkathi eziningana zokuthuthukiswa kwe-intrauterine ye-fetus. Isikhathi sokuqala ukubunjwa kwe-zygote, ngenkathi isenzo socansi singena emzimbeni, bese singena esibelethweni nasesibhucwini sezintambo, lapho bahlangana khona neqanda kanye ne-spermatozoon enamandla kakhulu engena kuwo futhi ukuhlanganiswa kwe-nuclei yabo kwenzeka. I-zygote eholayo iqala ukwahlukanisa futhi iqhubekele emgodini we-uterine ngenxa yezingqinamba zamatayipi okhokho. Ngenxa yokuhlukaniswa kweqanda lesisu, amaqabunga ama-embryonic amathathu akhiwa, okuyinto izitho kanye nezicubu ezizokwenziwa kamuva. Ngosuku lwesishiyagalolunye nesikhombisa, umbungu ufakwa esibelethweni. Inkathi yesibili ibizwa ngokuthi i-fetal futhi ihlala kuze kube amasonto angu-12. Phakathi nalesi sikhathi, umbungu uhlanganiswa ne-villi, ezinye zazo zikhula zibe udonga lwe-uterine futhi ziguqulwa zibe yi-placenta. Inqubo yokwehlisa isiphetho izinyanga ezingu-4. Kusukela ngesonto lama-12 isigaba sokubeletha sokukhula kwentombazane siqala, ngoba kusukela manje embryo ibizwa ngokuthi i-fetus. Isikhathi sokutshala nokufakwa kwamapulangwe kubhekwa njengesikhathi esibucayi sokuthuthukiswa kwe-intrauterine, kusukela ngalezi zikhathi umbungu uzwela kakhulu kuma-agent abonakalisa
Ukuthuthukiswa kwe-intrauterine ngesonto
Phakathi nokukhulelwa konke ne-fetus, ushintsho olubalulekile lwenzeka okwenza ekubunjweni kwezitho kanye nokwahlukana kwezicubu. Izigaba ezibaluleke kakhulu zokuthuthukiswa kwe-intrauterine zimi kanje:
- emasontweni ama-4, i-embryo ifakwa esibelethweni;
- Amaviki angu-12 inqubo yokufaka inhlawulo iphela;
- ngeviki 13 ungakwazi ukunquma ubulili bomntwana ongakazalwa;
- ngeviki le-14 isitho sokuzwa sakhiwe futhi ingane isivele izwa izwi lomama, libona umculo;
- ngesonto lesithupha, ingane iqala ukuhamba;
- ngeviki 18, ama-reflexes ase-intrauterine akha. Ingane ingagwinya i-amniotic fluid, iphuze umunwe, ivale amehlo akhe ekukhanyeni okukhanyayo nokucasula okwenziwe nge-cornea iso;
- Ngesonto lama-20 umntfwana ufinyelela usayizi omkhulu ngokwanele, ukuthi umama wakhe uqale ukuzizwa evuselela;
- Ngesonto lama-24 ingane isakhiwe ngaphandle, kodwa izitho zakhe azange zikhule ngokwanele, futhi uma kwenzeka kuzalwa, ingane enjalo ayikwazi ukusebenza;
- ngesonto lama-25, isitho sombono kanye nomntwana sakhiwe, ngisho nokuba se-utero ekwazi ukusabela emthonjeni wokukhanya;
- ingane ezalwa ngesonto lama-28 ekuhlinzekeni kokunakekelwa kwezokwelapha okufanelekayo iyakwazi ukusinda. Kusukela ngesonto lama-28 ukukhula okujulile kwengane esiswini kuphawulwe futhi ukwakheka kwezitho zangaphakathi kuphele;
- kanye namaviki angu-37 okukhulelwa kubhekwa ukuthi uphelele futhi ingane isilungele ukuzimela ezizimele endaweni.
Ukufundwa kwentuthuko ye-intrauterine fetal - ultrasound
I-Ultrasound yindlela ewusizo evumela ukuthi uhlole ukuthuthukiswa kwe-intrauterine yengane amasonto. I-embryo iqala ukubonakala ngeviki lesi-5, lapho idlulela emgodini wesibeletho. Emasontweni angu-6-7 ungabona ukushaya kwenhliziyo. Emasontweni angu-9-13 no-19-22, ukulawulwa kwe-ultrasound kwenziwa, lapho ukwakheka kwezitho zangaphakathi, umsebenzi wabo nobukhulu babo kunqunywa. Uma kunesidingo, i-ultrasound ingabuyekezwa kaningi.
Kumele kukhunjulwe ukuthi ngesikhathi sonke sokuguquka kwesakhiwo sokukhulelwa kwenzeka kanye nokungalingani emzimbeni kamama (izifo, imikhuba emibi, umsebenzi womzimba) kungaphazamisa ukwakhiwa kwengane ezayo.
