Ngakhale kuti ali ndi matenda osokoneza bongo ndipo amakhulupirira kuti pakatha milungu iwiri mimba isanakwane (mimbayo siimakhala ngati mimba), kamwana kameneka kamayamba kale kukhala moyo wake ndikukula mogwirizana ndi nthawi yake. Ndipotu, kuyambira maola oyambirira a mimba, dzira la fetal lakhala likudziŵa.
Pambuyo pa umuna wa dzira, umene umachitika mu falsipian tube, zygote - dzira la umuna limayamba kugawidwa . Pambuyo pokonza njira yopyolera podutsa, patsiku lachinayi dzira la fetus limasanduka blastocyst. Mu chiberekero cha chiberekero, blastocyst ikuyandikira malo omangidwe a dzira - kulowetsa mu chiberekero, izi zimatha pafupifupi masiku awiri. Mazira nthawiyi amakhala pa chiberekero cha chiberekero komanso mothandizidwa ndi chorionic villi mwamphamvu kwambiri m'chiberekero.
Mphuno yaumunthu ili ndi masabata awiri
Mphuno yaumunthu, yomwe ili ndi zaka ziwiri, ili mu bubulu la Graaf. Iye sanasinthe kwambiri pokhapokha atatenga mimba, adayambitsa kale ziwalo zowonjezereka-amnion, chorion, yolk sac, zomwe amapereka zonse zofunika kuti apite patsogolo. Pa masabata awiri, mwana wosabadwayo amapanga mtima wa selo ndi cytoplasm. Pamapeto pa masabata awiri, kamwana kameneka kamakhala dzira lokhwima, lomwe lili ndi phokoso lopangidwa ndi cytoplasm, chigoba chowala kwambiri, ndipo "chokongoletsedwa" ndi korona wa maselo a epithelial.
Kutenga masabata awiri - kukula kwa fetal
Monga momwe kafukufuku amasonyezera, kukula kwa mwana wosabadwa pa sabata 2 sikukwanitsa kuyeza, komanso kulemera kwa mwana mu masabata awiri. Kukula koyamba, komwe kumatsimikiziridwa - 0.15 mm, kunalembedwa sabata lachitatu la mimba, ndi kulemera - 1 g - kokha pa sabata 8.
Kukula kwa fetus mu masabata awiri

Pansi pa zovuta kuti chitukuko cha msinkhu wa zaka zapakati pa masabata awiri chisamangidwe, sichidzaikidwa ndipo chidzabwera ndi kusamba. Ndipo mkaziyo sadziwa konse kuti ali ndi pakati. Zinthu zoterezi zingakhale zochititsa mantha, zochitika pamaganizo, mankhwala.
Kodi mwanayo amawoneka bwanji ngati masabata awiri?
Kuti mudziwe, ndikwanira kupanga ultrasound yomwe siidzawonetsera momwe mawere akuyang'anirako, komanso kuti adziwe kutalika kwa mimba. Ngakhale kuti mwana wosabadwayo sanawonedwepo , panthawi ya ultrasound n'zotheka kudziwa mlingo wa mtima.
Mimba imakhala ikudziwika kwa masiku 14, ziwalo zake zofunikira zimapangidwa, mtima wake ukhoza kumveka. Uyu sali kamwana kokha. Uyu ndi mwana wanu wam'tsogolo, yemwe adzabadwire mu masabata 38.
