Amasonto ayishumi nambili okukhulelwa yisikhathi esibalulekile sowesifazane, njengoba lokhu sekuphela kokuqala kwekota. Phakathi nalesi sikhathi, i-placenta ikhiqiza i-progesterone eyanele, futhi ngokuqedwa komsebenzi we-hormonal, umzimba ophuzi kancane kancane wehla. Ngalesi sikhathi, i-trimester yokuqala ihlolwe (kusuka emavikini angu-11 kuya kwangu-13 nezinsuku ezingu-6), ukukhomba iqembu eliyingozi ngenxa yezinto ezingavamile, kanye ne- ultrasound yokuqala ekukhulelweni . I-Ultrasound emavikini angu-12 wokubeletha, ukuthuthukiswa kwe-fetus kubonisa ngokunembile kakhulu, ikakhulukazi i-exponent.
Ukulinganisa okubalulekile, okunezinye zezindinganiso eziyinhloko, yi-CTE ye-fetus emavikini angu-12. Lesi sibonakaliso sisetshenziselwa ukunquma ubukhulu be-fetus futhi sibone isikhathi sokukhulelwa ngokuhambisana nesisindo esilinganiselwe. Ubukhulu be-coccyx-parietal yamaviki angu-12 buba ngu-5.3 cm. Uma ukuthuthukiswa kombungu kuhamba ngezinsuku ezingenazinkinga, futhi kwanda ngo-1 mm ngosuku, umama womuntu wamaviki angu-12 uyasheshisa izinga lokukhula kuya ku-1.5-2 mm ngosuku. Odokotela batusa ukulinganisa i-CTE ye-fetus emavikini angu-11 noma angu-12.
Kumele kukhunjulwe ukuthi ubukhulu besayizi we-coccygeal-parietal buxhomeke esikhathini sokukhulelwa kuze kube usuku, ngakho-ke iphutha elivamile liyizinsuku ezintathu kuya kwezine. I-CTE ejwayelekile yomsindo we-embryo ngu-51 mm. Ngokuphambuka okuncane, ungakhathazeki - ukususwa okujwayelekile kusuka ku 42 kuya ku-59 mm kunokwenzeka.
Ukuqhathanisa, sikhombisa i-CTE ye-fetus emavikini angu-11: inani elijwayelekile lingama-42 mm, ukwehluka okuvunyelwe kujwayelekile kuyama-34-50 mm. Uma uqhathanisa lezi zikhombisi, ungabona ukuthi kubaluleke kangakanani usuku ngalunye oluyi-ultrasound.
Embryo amasonto angu-12
Kumama ozayo ngokuqinisekile kuyathandeka ukuthi kubukeka kanjani nokuthi izithelo zingenzani emavikini angu-12. Phakathi ne-ultrasound, umama angabona indlela ingane yakhe inamathela ngayo umunwe, futhi uzwe izinsimbi ezingu-110-160 ngomzuzu ukushaya inhliziyo encane. I-kid ishukumisela futhi ijika ngesigqila sesisu, isifuba sehla futhi siphume ngesikhathi sokuphefumula. Futhi, isithelo sesivele sinamandla okugcoba, vula umlomo wakho bese uguqula iminwe yakho.
Ngokuphathelene nezinkomba zokuthuthukiswa, kufanele kubone ukuvuthwa kwe-thymus gland, okubangela ukukhiqizwa kwama-lymphocytes ngomzimba nokuthuthukiswa kokuzivikela. I-pituitary gland iqala ukukhiqiza ama-hormone athinte ukukhula komntwana, umzimba we-metabolism nomsebenzi wokuzala womzimba. Isibindi se-embryo siqala ukukhiqiza i-bile, esizosiza ekugayeni kokudla. Uhlelo lokugaya isilungele ukugaya i-glucose.
I-embryo isisindo esingama-9-13 amagremu amasonto angu-12, isithelo sisuka futhi sihlezi. Ubude kusukela emgqeni kuya ku-sacrum cishe ku-70-90 mm. Inhliziyo ye-embryo ngalesi sikhathi ineamakamelo amane: i-atria amabili nama-ventricle amabili, futhi ukuphindaphindeka kwezinto ezihlukeneyo kuyahlukahluka kusuka ku-150 kuya ku-160 ukushaya ngomzuzu. I-sky clouds ithoma ukwakha, amazinyo amazinyo obisi, kanye ne-larynx, ama-vocal cords akha.
Le nkathi yentuthuko yabafana ibaluleke kakhulu. Esikhathini sokusebenza okusebenzayo kwe-testosterone, okukhiqizwa izigulane zobulili zabafana, izitho zangaphandle zobulili ziqala ukwakha - ipeni kanye ne-scrotum. Uma kwenzeka ukwephula lo msebenzi, i-hermaphroditism ingabonwa.
Umama uzizwa kanjani emasontweni angu-12 okukhulelwa?
Esikhathini esijwayelekile sokukhulelwa nokuthuthukiswa komntwana, owesifazane okhulelwe kufanele athole kusuka ku-1.8 kuya ku-3.6 kg. Izinga lokuthola isisindo liphakathi kuka-300 no-400 amagremu ngesonto. Uma uthayipha isisindo ngaphezu kokuvamile, udinga ukunciphisa inani lama-carbohydrate alula (amaswidi, amakhukhi, i-halva, njll).
Abesifazane abaningi bakhathazekile ngokubukeka ngalolu suku lwamabala aqoshiwe ebusweni, entanyeni, esifubeni, nasekubukeni komugqa omnyama kusuka enkabayeni kuya e-pubis. Noma kunjalo, akufanele ukhathazeke, lezi zibonakaliso ezijwayelekile, futhi maduzane bazozalwa kabusha.
I-embryo emavikini angu-12 uye waphumelela ngendlela yokuphila yama-embryonic futhi emva kwamasonto angu-12 kuthiwa yi-fetus. Esihlokweni sethu, umama wesikhathi esizayo uzothola ulwazi oluningi oluwusizo ngaye, ukuze ukwazi kangcono ngekusasa lakhe elizayo.
