Mayi, monga lamulo, amadziwa za mimba yake pamasabata 2-3, pamene alibe msambo. Zitsimikizirani kapena kukana kukayikira za mimba zingatheke ndi mayeso apadera, zowonjezera kuwonjezeka kwa griadotropin ya chorionic mu mkodzo (mu hCh m'magazi mungathe kudziwidwa muzipatala zapamwamba komanso zofufuza). Pa sabata lachisanu la chiberekero, kamwana kameneka kamasunthira kale ku chiwalo cha uterine, maselo ake akupitirizabe kugawa nawo mbali. Tiyeni tikambirane za zomwe zimachitika pa mimba mu masabata asanu, komanso kukula ndi kukula kwa mwanayo.
Masabata asanu ndi asanu - kukula ndi kukula kwa mwana
Pa sabata lachisanu la mimba, mwana wosabadwayo ali wofanana ndi silinda ya oblong. Kukula kwa fetus pa sabata lachisanu la mimba ndilo 1.5-2.5 mm. Maselo amagawikana kale osati misala, mutu ndi phazi zimatha kusiyana, malo a mapangidwe ndi miyendo (ziboliboli za kumtunda ndi kumapeto kwenikweni zimatsimikiziridwa), thumba ndi kumbuyo. Chochitika chofunika pa kukula kwa fetus mu masabata asanu ndiko kuyamba kwa mapangidwe a mtima ndi mitsempha yambiri ya magazi pamodzi ndi ziwalo za kupuma (mapapo ndi trachea). Pamapeto pa sabata lachisanu, mabala oyambirira a mtima amadziwika.
Pa mwana wosabadwa mu masabata 4-5 pali kupangidwira koyambitsa kansalu kameneka, kumene msana ndi msana zimatha. Mapeto ake a neural chubu amayamba kukula ndipo amachititsa kuti ubongo umapangidwe. Panthawi ya neural tube, zotchedwa seite zimapangidwira, zomwe zimakhala minofu ya minofu. Pa sabata lachisanu la chiberekero, kukula kwa chiwindi ndi kapangidwe kumapangidwa.
Mphungu pa sabata lachisanu la chitukuko ili mu yolk sac, kukula kwake ndi 1 masentimita, ndipo kukula kwa mwana wosabadwa sikuposa 2.5mm. Yolk sac ndi zigawo ziwiri zoteteza, zomwe zimapanga zakudya ndi maselo ofiira a mwana wosabadwa.
Fetal ultrasound pa sabata 5
Ultrasound ndi njira yolondola kwambiri komanso yamakono, yomwe ikukuthandizani kuti muone kukula kwa fetus mu masabata 5-6. M'njira iyi, ultrasound imachitidwa pokhapokha ngati dokotala akuchenjeza chinachake, sizowunika.
Pa sabata lachisanu la mimba, ultrasound ikhoza:
- onetsetsani kuti nthawi yayitali ndi chiwerengero cha mazira mu uterine;
- onetsetsani chigwirizano cha embryo, mutu ndi phazi kumatha;
- Kuyeza kukula kwa mwana wamwamuna - CTE ya mwanayo imatsimikiziridwa poyesa mtunda kuchokera ku korona kupita ku khosi mu masabata asanu, kukula kwake kudzakhala 1.5-2 mm;
- Ultrasound pa masabata asanu akhoza kudziwa kuti pali kuthekera kochotsa mimba.
Kumverera kwa mkazi pa sabata lachisanu la mimba
Pa sabata lachisanu lachisanu cha mimba, mayi akhoza kuyamba kumva maonekedwe oyambirira a toxicosis : kunyoza, kusanza, kulakalaka kudya kapena kusintha miyambo yowonjezera (mwina mungafune mchere kapena wokoma), kugona, kukwiya, kufooka (nthawi zambiri kumayenderana ndi kuthamanga kwa magazi). Chiwerengero cha mayi wamtsogolo sichinafikebe,
Kusintha kwa thupi la mkazi, ziwonetsero za toxicosis zimakhudzana ndi kusintha kwa mahomoni - kuwonjezeka kwa progesterone ndi chikasu cha mimba. 5 sabata imodzi ya mimba ndi imodzi mwa nthawi zovuta kwambiri pamene mkazi ayenera kudziletsa yekha ku zinthu zovulaza (kachilombo ka HIV, utsi wa fodya ndi mowa), momwe angasokoneze mapangidwe a ziwalo zoberekera ndi machitidwe.
