Vhiki yechisere yekutakura inoreva 2 trimester. Kune mukadzi, izvi zvinoreva kuguma kwe toxicosis uye kuonekwa kwemuviri. Pamucheche pavhiki yechi17 yekuzvitakura, zvinenge zvikamu zvose uye zvigadziriro zvatove zvakagadzirwa, asi zvinoramba zvichivandudza. Muchikamu chedu, zviitiko zvekukura kwe fetal pavhiki 17 uye kuchinja mumuviri wemai anouya zvichafungidzirwa.
Mavhiki masere ekuberekwa - chimiro, uremu uye chiyero che fetus
Kuti uone urefu hwemucheche, edza iyo inonzi inonzi coccygeal-parietal size. Kubwinya kwe-coccyx-parietal (CT) yemukomana pamasvondo makumi maviri nemasere inokwana masendimita 13. Kurema kwemucheche pamasvondo makumi maviri nemashanu ndiko 140 magiramu.
Munguva iyi, maitiro ezvirwere zvekuzvidzivirira anogadzirwa uye anotanga kushanda mumwana, iyo inopferon uye immunoglobulin inogadzirwa, iyo inodzivirira mwana kubva kune utachiona hunogona kupinda mumuviri waamai. Izvo fetus pamasvondo gumi nemashanu anotanga kuonekwa uye kuvaka mazamu asina mafuta uye mafuta uye chepakutanga marisi. Basa ravo guru nderokuchengetedza, uye mafuta anoisa pasi anotora chikamu chinoshanda mukati mehutano hwe thermoregulation.
Mwoyo wemwana wakatove wakagadzirwa nemavhiki makumi mapfumbamwe, asi unoramba uchivandudza. Iropitation ye fetus pamasvondo gumi nemashanu inowanzo mukati me 140-160 kurohwa paminiti. Chiitiko chakakosha panguva iyi yekuzvitakura ndiko kuumbwa uye kutanga kwekushanda kwezvipembenene zve endocrine: pituitary uye grenal glands. Irotical cortical ye adrenal glands panguva iyi inotanga kusunungura glucocorticoid hormone (cortisol, corticosterone).
Iyo fetus yemukadzi inoita chibereko. Pavhiki yechi17 yehutumbi, fetus iri kuisa meno okugadzikana, ayo anowanikwa pakarepo mushure mazino emukaka. Nhengo yekunzwa inowedzera panguva iyi, embryo pamasvondo 17 anotanga kusiyanisa inzwi, rinopindura mazwi evabereki.
Manzwiro emukadzi pamasvondo gumi nemashanu
Chirwere chechipiri chepamuviri vakadzi vanoonekwa sevanonyanya kufarirwa apo chekutanga kuoraxicosis inonyangarika, uye mudumbu hausi mukuru. Zvisinei, pamasvondo gumi nemanomwe ekuberekwa, ukuru hwemuviri kwave huri kunyanya kuwedzerwa nechibereko chepamuviri, zvikurukuru muvakadzi vashoma, izvo zvichatsausa chimiro. Muchembera panguva ino inopfuura kumusoro kwembilicus pa17 cm Mukadzi panguva ino haagoni kusapfeka jeans kana mupfupi mutsvuku. Zvipfeko zvinofanirwa kunge zvakasununguka zvakakwana kuti zvisapedze mwana.
Pavhiki yechi17 yehutumbi, mukadzi anogona kutanga kunzwa kunzwa kusingafadzi mukati mechiberekwa, izvo zvinobatanidzwa nekuwedzera kwake nokukurumidza. Kana manzwiro aya achiunza kusagadzikana, zvino izvi zvinofanira kuudzwa kune chiremba wako.
Chibereko pamasvondo 17 chinosvika kukura zvakakwana zvakakwana, kuitira kuti amai vanouya vanotanga kunzwa vachikurudzira. Mafungiro emucheche pamasvondo gumi nemashanu anotanga kuisa marara ose uye vamwe vakadzi vepakutanga. Munguva iyi, mukadzi acharamba achishungurudzika nechishuvo chekurota, izvo zvinobatanidzwa nekudzvinyirira kwechibereko chinokura pachikanda.
Kutora kuongorora mumavhiki 17 ekuzvitakura
Nzira huru ye fetal examination panguva ye17 vhiki yekuzvitakura is ultrasound. Iyo ultrasound ye fetus pamasvondo gumi 17 haisi
Amai vane ramangwana panguva ino vanofanira kupfuurira kutungamirira mararamiro ane hutano: vadzivirira utachiona, kushushikana, kudya zvakanaka, kazhinji kuva mumhepo itsva. Mukuwedzera, zvakakosha kutaura nemwana wako weramangwana, teerera kumimhanzi yakadzikama, nokuti iri panguva ino iyo mwana anotanga kunzwa zvose.
