Ndezvipi zvinoshandiswa nemucheche?
Kunze kwekunze, iyo fetal egg inowanzoshandurwa kuva mucheche. Nhengo dzomukati dzayo dzinowedzerawo kuoma. Iko zvino yakafanana ne diski inosanganisira masheya matatu emasero akaenzana. Mu embryology, ivo vanowanzozonzi ma embryonic sheets. Nenguva iyo inopa zvivako zvemasimba zvinokonzera kumagadziro ega ega uye nhengo dzomwana asati aberekwa.
Ikunze, kana kuti iyo inowanzonzi yakasara, ndiyo ectoderm. Pakarepo kubva pairi yakaumbwa zvakadai se:
- ganda integument;
- bvudzi;
- misumari.
Mukuwedzera, gira rekunze rinotora chikamu chakajeka mukuumbwa kwenheyo yehutano, iyo inoratidzirwa, mazino.
Pakati pepakati, iyo mesoderm, inosimudzira mapfupa, maitiro anogadzirisa, mishonga inopinza, zvinyorwa zvepabonde, zvepabonde uye zvekufamba.
Endoderm, iyo yepakati, ndiyo nheyo yekuumbwa kwehutachiva hwemuviri, chiropa, glands rekati secretion.
Pahutachiona husina maturo 4 mavhiki, pamucheto wekubatanidza kwema fetal egg kumuranda uterine, mutezo wemitsipa yeropa inotanga kuumba. Ndiyo iye anopa kumukira .
Zvingaita here kuti utange kubata pamuviri pazuva iroro iwe pachako?
HCG pamusana wekuberekwa kwekuberekwa kwekuberekwa kwechina kunosvika pakudzidza. Nokudaro, kusimbisa chokwadi chaiyo chekuita gesheni, mukadzi anogona kushandisa chirongwa chinowanzoitwa.
Kazhinji, kutungidzika kwehomoni ndeye 25-156 mMe / ml.
Ultrasound pamusana wechina wekudzivirira hutachiwana hunoitwa kuti uone chokwadi chekuita gumbo, kuongorora kwezviri mukati memucheche yekuberekwa. Kushandiswa kwe-high-resolution ultrasound midziyo inobvumira kubvisa kukanganisa kwakadai sa anembrionia, apo embryo isipo.
