Mukadzi, sekutonga, anodzidza nezvekudzivirira kwake pamasvondo maviri, kana asingakwanisi kuenda kumwedzi. Tsimbisa kana kuti kuramba kusafungidzika kwekuzvitora kunogona kuitwa nemuedzo unokosha, unoziva kuwedzera kwechirionic gonadotropin mumuguta (mu hCh muropa rinogona kutsanangurwa chete mumakiriniki edzimakirini uye anoongororwa mabhuku). Pavhiki yechishanu yehutumbi, embryo yakatotamira kune uterine cavity, masero ayo anoramba achigoverana nekushingaira. Ngatitaurei pamusoro pezvinhu zvekudzivirira kwepamuviri mumavhiki mashanu, pamwe chete nekuvandudzwa nekukura kwe fetus.
5 masvondo masikati - kukura uye ukuru hwe fetus
Pavhiki yechishanu yekuzvitakura, fetus inofanana neylinda yakareba. Kukura kwema fetus pavhiki yechishanu yekuzvitakura kunowanzowanikwa 1.5-2.5 mm. Masekete anenge atova akaparadzaniswa kwete nechisimba, musoro netsoka zvinotanga kupesana, nzvimbo dzekugadzirisa mashizha nemakumbo (rudiments yepamusoro nepamusoro marefu inotsanangurirwa), mimba uye kumashure. Chiitiko chinokosha mukukura kwe fetal mumavhiki mashanu ndiko kutanga kwekuumbwa kwemwoyo nemidziyo yeropa huru pamwe nemitezo yekufema (mapapu uye trachea). Pakupera kwevhiki yechishanu kukwidzwa kwekutanga kwemoyo kunoratidzwa.
Pamusoro pekuberekwa mumasvondo mana kusvika ku5 kune kushingaira kwekugadzirisa kwe-neural tube, kubva kwairi iyo musana uye musana wemugwagwa zvichazogadzirwa. Kupera kweganda reNeural tube zvishoma nezvishoma kunowedzera uye kunopa kuumbwa kweuropi. Muchikamu chemuNeural tube, zvinodanwa kuti somites zvinoumbwa, izvo zvinowanikwa mumasumbu. Pavhiki yechishanu yekukura kwemucheche, rudiments yechiropa nepascreas inoumbwa.
Iyo embryo pavhiki yechishanu yekufambisa iri mu yolk sac, iyo yakareba iyo masendimita 1, uye ukuru hwema fetus hausi ma 2.5 mm. Iyo yolk sac ndeyekudzivirira kwechipiri, pakati payo ndiko kugadzirwa kwemakemikari uye masero matsvuku eropa nokuda kwembryo inoumba.
Fetal ultrasound pavhiki 5
Ultrasound ndiyo nzira yakarurama uye yemazuva ano, ichikubvumira kuti uone kukura kwe fetus mumavhiki mashanu kusvika matanhatu. Muchirevo ichi, ultrasound inowanikwa mumamiriro ezvinhu apo chiremba ari kuratidza chimwe chinhu, haisi kuongorora.
Pavhiki yechishanu yekuzvitakura, ultrasound inogona:
- chengetedza nguva yekuita kwemazuva uye nhamba yemambrus muuterine cavity;
- chengeta kusungirirwa kwemukati, iyo musoro uye tsoka dzinoguma;
- kuti aenzane nehoccyx-parietal ukuru hwemucheche - iyo CTE ye fetus inotsanangurwa nekuyera kure kure kubva korona kuenda kune coccyx mumavhiki mashanu, hupamhi hwayo huchava 1.5-2 mm;
- Ultrasound pamasvondo mashanu anokwanisa kusarudza kutyisidzira kwekubvisa pamuviri.
Manzwiro emukadzi pavhiki yechishanu yekuzvitakura
Pavhiki yechishanu yekuzvitakura, mukadzi anogona kutanga kunzwa kunzwa kwokutanga kwe toxicosis : kusuruvara, kurutsira, kuwedzera kudya kudya kana kuchinja kudya (zvinogona kudiwa munyu kana kutapira), kurara, kusagadzikana, kushaya simba (kazhinji kazhinji kunobatanidza neropa rezasi). Chimiro chemai vemazuva ano hachina kuchinja,
Kuchinja mumuviri wemukadzi, zvichiita zviratidzo zve toxicosis zvinosanganiswa nekushandurwa kwemashure ehomoni - kuwedzerwa kwekugadzirwa kweprogesterone nehutano hwemuviri. 5 vhiki yekuzvimba ndeimwe yezvinonyanya kukosha apo mukadzi anofanira kuzvidzivirira kubva kune zvinokuvadza (utachiona hwehutachiona, utsi hwefodya nedoro), sezvo zvinogona kuvhiringidza kuumbwa kwenhengo dze fetal uye zvirongwa.
