Mwedzi wokutanga wekuita pamuviri: kukura kwemukati wemavhiki nemazuva mumufananidzo nemavhidhiyo

Vazhinji vevakadzi mumwedzi wokutanga wekudzivirira havazivi kunyange nezvemamiriro avo anofadza. Chimiro uye chiyero chemuviri zvinenge zvisingashanduki. Zvisinei, zvose metamorphoses pane iyi izwi mukati, uye kwete kunze. Kubudirira kwembryo kunoenda mumatanho akawanda. Iko embryo zvishoma nezvishoma inoumba, kuchinja vhiki rese. Hazvibviri kuinyatsozviongorora, asi zviri nyore kufungidzira mumifananidzo kuti upenyu hutsva hunoberekwa sei.

Mucheche, mucheche, kana fetus: inogadzira sei

Nguva yekuita nguva inotarwa kubva panguva yekupedzisira yekuenda kumwedzi. Muchiitiko ichi, kubata pamuviri uye mavheti anotangira anoitika anenge mazuva 14 gare gare. Vhiki yekutanga inoratidzwa nekuyerera kwekuenda kumwedzi. Muchiitiko ichi, muviri wemukadzi unochinjwa kune chinzvimbo chawo chitsva. Pamamwe mazai akawanda, chete 1 inotanga kubvaruka. Mucheche yeuyo mutezo inopera zvishoma nezvishoma. Rutsva rutsva runoumba panzvimbo yezvimedu zvakarambwa. Sezvo zvakadaro, hakuna hutumbi huripo. Kunyange pa ultrasound haisi nguva dzose kugona kutsvaga kuchinja uku.

Chikamu chechipiri chinoratidzwa nekuonekwa kweii, iyo inogona kunzi mutungamiri. Inogadziriswa mumhando yehuturi iyo iripo pane ovary. Kuguma kwechitubu ichi ndiko kubuda kweivulation. Ivo vesicle inoputika, mushure mokunge zhi pacharo rinosiya mimba yemimba yemukadzi. Zvakare, hazvikwanisi kunzi chibereko, sezvo chiri chimiro chiduku zvikuru, sezvinoonekwa kubva pamufananidzo, achipinda mu fallopian tube. Kwemazuva maviri mwana wemangwana anochengetwa ipapo. Mushure mezvo, zvinoramba zviripo kuti kumirira spermatozoa. Kune mavhidhiyo akawanda emarangariro pamusoro pekuti "musangano" wavo unowanikwa sei. Pasi pane umwe wavo.

Kukura kwe fetus: mifananidzo yemazuva ake okutanga

Kusvikira mwedzi miviri, pamuviri unonzi embryonic, nokuti fetus iri mumamiriro embryo. Kubudirira kwemukati, iyo inogona kuteverwa kuburikidza nemifananidzo yakaratidzwa nemifananidzo, zvinoreva musangano we ovum uye mbeu. Chigumisiro chekubatana kwavo nhizha tsvuku, iyo inonyanya kukosha mumwedzi wokutanga.

Kunyorera! Icho chiri chikamu chichena kuti estrogen uye progesterone inosunungurwa, iyo inosungirwa kuchengetedza fetus.

Kushanda kwemuviri uyu kunosanganiswa ne toxicosis. Kazhinji, mushure mokunge mutoro wose wekuchengetedza mwana wemunguva yemberi inopfuurira kusvika ku-placenta, zvose zvinoratidzika zvisinganakidze zvemwedzi yekutanga yemamiriro ezvinhu anofadza kupfuura. Izvi zvinosanganiswa nevhiki 14-16.

Kana zviri zvezvisikwa zvemuitiro wezvinofadza mazuva 15-28, zvinosanganiswa nehutachiona hwembryo mukati mehupamhi hwemukati wechipupuriro cheuterine cavity. Panguva imwechete pa ultrasound, zviri nyore kutsvaga mitsara yevana remangwana.

Mufananidzo wemazamu kwevhiki: 1 nevhiki mbiri

Zuva roga roga rekumbryonic rinonakidza. Mushure mezvose, embryo inowana zvinhu zvakasiyana nemwana chaiye, pasinei nokuti dumbu, sekutonga, rinotarisa sekare uye harisi kupa hupenyu hutsva hunobva mairi. Vhiki yekutanga inobatanidza nehutano hwehutano. Iko kubatanidzwa kwechikadzi chesero nemurume. Sokutonga, zvinhu zvose zvinotenderera mu fallopian tube, mumagetsi ayo. Muvhidhiyo iri pasi apa unogona kutevera zvinyanzwisisiro zvemukati wemukomana.

Ngwarira! Maawa mashomanana chete mumazuva 1-7 akakwana kuti sero revakadzi rinogadziriswa riparadzanise pamushanyo wepamusoro mukufambira mberi kweiometri, mushure mokunge inopinda mubereki kuburikidza ne fallopian tube.

Mushure mekuparadzaniswa, muviri wakakosha unoumbwa. Kunze, zvinotarisa chimwe chinhu chakafanana nemabhiriji, sezvaunogona kuona pane imwe yemifananidzo. Panguva ino, embryo mune gynecology inowanzonzi morula. Pazuva 7, rinowanzotorwa muchibereko. Mamwe masero anoumba nhengo uye umbilical cord. Kubva kune mamwe masero, nhengo dzomukati nematukisi emucheche zvichawedzera. Vhiki yechipiri yemwedzi wekutanga wekudzivirira inoratidzirwa nekudzika kwemafuro e morula mukati mehutu hwemuviri. Iyo fetus inowedzera mumazuva 8-14:

• placenta;
• umbilical cord;
• the neural tube.

Mufananidzo wevana mudumbu nemazuva: masvondo matatu ne4

Pasinei nokuti chiitiko pamusi wechitatu wekuzvitora chinotarisa, mazuva gumi nemaviri ekubudirira anokosha. Iyi nhanho inobatanidza nekuumbwa kwezvinyorwa zvekutya, kushambadzira, kuporesa, kunyanya, kugadzirisa zvirongwa. Mumufananidzo iwe unogona kuona kuti mwana wechauya anoita sei. Bhuku rakafara mapaundi. Icho chiri munzvimbo ino iyo fetus ichazove nayo musoro. Zuva 21 ndiko kutanga kwekusimbiswa kwete kungoita uropi.

Kunyorera! Panguva ino yemwedzi wokutanga wekudzivirira, mwoyo unotanga kurova.

4 vhiki nemufananidzo uye tsanangudzo

Mumazuva 22-28, sezvinogona kutongwa kubva pamufananidzo uye video, fetus iri inonyatsoonekwa pane ultrasound. Nguva yacho inobatanidza nekuenderera mberi kwebhukiti uye kukura kwezvikamu. Kune zvivako:

• chiedza;
• chiropa;
• itsvo;
• the spine.

Moyo unotanga kushanda zvakawanda. Iko kune mahwendefa edu, uye nezuva rechipiri neural tube inogadzirwa.

Pakupera kwekutanga kwekuvandudzwa kwemuviri wevakadzi, musana uye musisimu inoumbwa. Uyewo madiki anowanikwa mumusoro, ayo anozove maziso.
