Kuwo wonke owesifazane ovamile, ukuqaphela ukukhulelwa kwakhe kanye nenkathi yokulinda yokuvela kwengane izikhathi ezibuhlungu kakhulu. Kwenzekani kulo mzuzu emzimbeni wakhe? Ake sizame ukubheka esibelethweni ...
Isonto lokuqala
Kuze kube manje, umntwana unomqondo ongaphezu komzimba wangempela. Isibonelo salo (ngokuqondile, isigamu saleso sibonelo) singenye yezinkulungwane zamaqanda ezinsikazi "ezisendlini" yazo - ama-ovari. Ingxenye yesibili yesibonakaliso (obaba) ayinayo ngisho nesikhathi sokuma esivumelwaneni esivuthiwe - lokhu kuzokwenzeka cishe emavikini amabili. Silinde, mnumzane.
Isonto lesibili
Emzimbeni wesifazane, imijikelezo emibili ebalulekile yezinto eziphilayo ibonakala cishe ngesikhathi esifanayo: i-ovulation - ukubukeka kweqanda elivuthiwe elungele ukukhulelwa; futhi phakathi nomjikelezo we-endometric, udonga lwe-uterine lulungele ukufakwa kwesitokisi esakhiwe. Zombili imijikelezo zihlobene eduze komunye nomunye, ngoba izinguquko ze-endometrial zilawulwa ama-hormone afihlekile ku-ovary.
Isonto lesithathu
Iqanda nesidoda bahlangane ne-tube fallopian. Ngenxa yokuhlangana kwabo, i-zygote yakhiwa - iseli lokuqala nesibaluleke kakhulu kwengane engakazalwa. Zonke izinhlamvu eziyi-100 000 000 000 000 zomzimba wakhe zingamadodakazi we-zygote! Izinsuku ezintathu emva kokukhulelwa, umbungu unamaseli angu-32 futhi ufana nombhebhe wamabelebhisi omile. Ekupheleni kwaleli sonto, inani lamaseli lizokhula libe ngu-250, ukuma kuzofana nebhola elingenalutho elilinganiselwa ku-0.1 - 0.2 mm.
Iviki lesine
I-fetus isesiteji sokuqala sokuthuthukiswa, ukukhula kwayo kungaba kusuka ku-0.36 kuya ku-1 mm. Ukutshalwa kwe-blastocyst kwagxila ekujuleni kwengqamuzana yesibeletho, futhi isikhumba se-amniotic saqala ukwakha. Lapha esikhathini esizayo kuzovela i-placenta kanye nenethiwekhi ye-vascular enegazi lomama.
Iviki lesihlanu
Kuleliviki ingane elandela izinguquko ezinkulu. Okokuqala, ushintsho lwayo luyashintsha - manje ingane ayisekho njenge-disk flat, kodwa iningi elifana ne-cylindrical 1.5 - 2.5 mm ubude. Manje odokotela babezobiza ingane ukuthi i-embryo - kuleli sonto inhliziyo izoqala ukushaya!
Iviki lesithupha
Ukuqothulwa kobuchopho nemilenze kukhula ngokushesha. Inhloko ithatha izinkulumo ezijwayelekile, amehlo, izindlebe zivela. Ngaphakathi kwe-fetus, izinguqulo ezilula zezitho zangaphakathi zakhiwa: isibindi, amaphaphu, njll.
Iviki lesikhombisa
Kule nkathi efanayo yokukhulelwa, indlebe yangaphakathi yengane ikhiwa, indlebe yangaphandle ikhula, imilenze iyakhiwa, futhi kuvele ama-rudiments. Ingane ikhule - ubude bayo buyi-7 - 9 mm, kodwa okubaluleke kakhulu - ingane iqala ukuhamba!
Iviki lesishiyagalombili
Izingane ziye zaba njengomuntu omdala. Inhliziyo ishaya, isisu sikhiqiza ijusi esiswini, izinso ziqala ukusebenza. Inkontileka yemisipha ngaphansi kwethonya lemicabango evela ebuchosheni. Ngegazi lomntanakho, ungabheka ukuthi i-Rh yayo inguyiphi. Aminwe namajoyina akhiwe. Ubuso bonyana buzuza izici zayo, inkulumo ebusweni iqala ukukhombisa ukuthi kwenzekani endaweni yayo. Umzimba wengane uphendukela ekuthinteni.
Iviki lesishiyagalolunye
Ubude bendodana kusukela emqhele kuya esikhwameni buba ngu-13-17 mm, isisindo - cishe u-2 g. Kukhona ukuthuthukiswa okujulile kobuchopho - kuleli sonto liqala ukwakhiwa kwe-cerebellum.
Isonto leshumi
