Izi ndi zoopsa "mu utero"

The nyumba loyamba lililonse la munthu - m'mimba mayi - nthawi kuchereza alendo ndi omasuka. Komabe, masabata 38 (pafupifupi 266 masiku), pakati pa mimba ndi kubadwa ndi kuopseza lalikulu, makamaka mu masabata oyambirira 8 kuposa wina aliyense pa moyo wawo wonse mpaka khumi ndi chinayi. Koma ngakhale chiopsezo kuthekera, ambiri mwa ana mu dziko lino mwangwiro wathanzi ndiponso m'nthawi yake.

Pachikhalidwe, madokotala kugawa intrauterine chitukuko cha magawo atatu otsatizana - trimester:

• 1 amatenga masabata 12;
• Chachiwiri - kwa masabata 12 mpaka 28;
• Chachitatu - milungu 28 mpaka tsiku la kubadwa kwa mwanayo.

Akatswiri ndi embryologists, nayenso amakonda kugawanitsa utero 3 wosiyana Nthawi: embryonic, embryonic ndi yoopsa.

Tonse kuyamba akhale zinthu zopanda, ali mawonekedwe a maselo awiri ophatikizidwa munali DNA 46, amene nawonso, ndi watanthauzo yaikulu kuchuluka kwa mfundo za moyo watsopano uyu anaima. N'zochititsa chidwi China amaona kuti kubadwa tsiku mimba, osati mwana wake. Mwambo umenewu ndi Dziwani kumathandiza chiwerengero cha mimba.

Pre-Natal chitukuko cha mwana ndi mlungu :

0-2 masabata. The gulu loyamba la dzira lidzayamba pambuyo maola 24-36 pambuyo umuna. Pa tsiku loyamba maola 40 pambuyo maselo woyambayo ali kugawa chomwecho. 3-4 tsiku zygote tichipeza maselo 12-16 ndi amatchedwa morula, kukula kwake ndi pafupifupi wofanana ndi singano. Patapita masiku 4, nagawira maselo anayamba kusiyanitsa nadzawasankhula mu awiri nyongolosi zigawo: mitundu kunja chipolopolo lotchinga Ndisanaumbidwe ndi - tsogolo nsengwa ndi kuchokera mkati ati apange Ndisanaumbidwe yoyenera. pofuna akupezeka mazira chubu, potero kupanga blastocyst. Iye ndiye wakudza chiberekero zipita M'mimbamo ake ndi amamangirira za uterine khoma endometrium wa - ndondomeko iyi akutchedwa implantation. Kumachitika mwa masiku 10-14 mayi atatenga pathupi. Pa nthawi imeneyi ikutha ndi embryonic ndi yoopsa chitukuko akalandire chithandizo akuyamba. Pafupifupi 60% ya blastocysts si Ufumuyo chiberekero choncho, samafuna nthawi embryonic. Ambiri a iwo yovuta matenda kakulidwe. Choncho, chikhalidwe salola kubadwa kwa anthu nonviable.

3-8 masabata. Umayamba pa embryonic chitukuko. Pa nthawi imeneyi, kaphatikizidwe wa mankhwala osiyanasiyana ogwetsa mayi chitetezo chokwanira, kuteteza kukana mwanayo minofu ya thupi zakunja chiberekero. Komanso, mwachangu apanga ndi timadzi anthu chorionic gonadotropin (tsiku limene mimba ndi matenda) - izo zimaleka msambo wa amayi. Komanso, kuchuluka mlingo kagayidwe kachakudya (10-25%), kupuma, magazi. Kuyambira ndi masabata 3 wa mwana wosabadwa ndi m'nyengo owonetsetsa kukula. The trimester chitukuko - m'nyengo morphogenesis, pamene pali tsamba la zimakhala anthu onse ndi ziwalo. Akatswiri a sayansi amanena kuti nthawi imeneyi ndi zapamwamba kwambiri ndi kothandiza njira kuti inu mukhoza kulingalira! Ngakhale yomanga ndi kukhazikitsidwa kwa makina ndi nawo zikwi za anthu ndi zinthu zamakono si zovuta ndondomeko, monga chitukuko intrauterine anthu!

Pa nthawi imeneyi, ndi kuchuluka kwa mimba mowiriza zokhudzana pamaso vuto aakulu chromosomal. Ndi mkulu Mwina wa padera chifukwa zinthu zosafunika mu chiberekero mkazi. 1 Only 6 mazira adzapulumuke masabata 8. Nthawi imeneyi, Ndisanaumbidwe ndi yovuta kwambiri kwa oipa kuchokera kunja, kotero mkazi ayenera kusamala kwambiri ndi kupewa kumwa, kumwa mowa, kusuta fodya.

Kumapeto kwa nthawi ili bwanji kafukufuku wakapangidwe kazachilengedwe wa mwanayo ndi kovuta.

Mu masabata 3 Ndisanaumbidwe ndi lalikulu kuposa choyambirira nthawi 10 chikwi.

Pa sabata 3 chitukuko anapanga chubu ubongo - ubongo ndi msana zinachitika anayamba umbilical chingwe ndi latuluka.

Sabata 4 - pakugona mtima. Pakutha masabata 4, iwo amayamba kumenya mosiyana kholo la. Anayamba kupanga maso. Ubongo chubu yatsekedwa. wosabadwayo kukula kugunda ndi pafupifupi 1 mamilimita patsiku.

Sabata 5 - kale zotheka kuwona manja ndi mapazi a mwanayo.

Mlungu 6 - anayamba kupanga kumaliseche. Pa zolephera mu stepi ino mwina mapangidwe anthu ndi maonekedwe a amuna ndi akazi. Mu nthawi imeneyi Ndisanaumbidwe ndi kale kuonekera pa ultrasound.

7 sabata, mapangidwe vuto anthu monga vuto. Inasinthira mafupa.

Ndi mlungu 8 anamaliza mapangidwe ziwalo zikuluzikulu. A chitukuko mofulumira ubongo.

Kuyambira masabata 9 panayambira nthawi yomalizira ya chitukuko yoopsa. Ndi masabata 13 a umayi akuyamba trimester lachiwiri la mimba. Mu nthawi imeneyi mwana limaoneka ngati wangobadwa kumene okha ang'onoang'ono. Ngakhale mutu akadali yakusatetezeka lalikulu. thupi anaweramuka ndi lengthened. Mayi woyembekezera akuti mphamvu. Ngakhale sizili kuthekera, chitukuko zina, monga ulamuliro, ndi bwino. Pa nthawi imeneyi ubongo wayamba ntchito.

Zapambuyo pake sinditi kusintha yakuti wa mwana wosabadwayo kukula kukula, kuwongolera ziwalo zake, kwa sabata 16, mayi kale akuona kayendedwe ake masabata 20 kuyamba kukula tsitsi.

Ndi miyezi 7 wosabadwa kale kupuma zokha, kupukusa chakudya, kwathunthu ukugwirira ntchito dongosolo excretory. Mu chochitika cha kubadwa msanga mwana akhoza kukhala ndi moyo paokha.

Iwo imatsimikizirika kuti pa miyezi 3 yomaliza ya chitukuko akalandire chithandizo, mwanayo kale amathandiza kuti m'dzikoli. Limayenda mwachangu, hiccups kulira. Yopangidwa mphamvu yakuti: kununkhira, kulawa, kuona, kumva. Ndi masabata 16 a mwanayo sagwirizana mawu (mawu chimasiyanitsa) kuwala.

Chifukwa, tsiku mwana 266 potsiriza amalandira mutu pansi udindo ndipo ndi wokonzeka pobereka.

5% ya anati mowiriza yoopsa kutha mimba mochedwa (pambuyo masabata 22).

Yoopsa chitukuko mlungu ndi mlungu - Chofunika kwambiri: mayi - kuzindikira njira mu thupi lake ndi kuopsa nawo, madokotala - kuwayang'anira chitukuko cha mwana wosabadwayo, ndi kwa anthu onse - kumvetsa kuti kuyambira lingaliro akuyamba mofulumira ndi chovuta kwambiri ndondomeko ya kumanga moyo watsopano, si wosazindikira nkhuni.
