Iyo fetus inoramba ichikura nesimba, mapfupa ayo anowedzera simba. Izvo zviyero zvakaenzana zvemucheche pamasvondo gumi nemasere ndeye 230 gramu. Iko kuverenga kwehuremu kunoitwa maererano nehupamhi hwakatemwa ne fetometry.
Fetometry ye fetus pamasvondo gumi nemana
BDP fetus (biparietal size) pamasvondo 18 e ultrasound iri 37-47 mm. Ukuru hwepamberi-occipital (LZ) inenge 50-59 mm. Mutsara wemusoro wemucheche ndeye113-161 mm, uye musikana wechipfu pane 102-144 mm. Izvi zvinoreva kuti pamasvondo gumi nemasere ekuberekwa kwehutachiwana hukuru hwemucheche ndeyekukura kwepuro duku kana peari.
Ukuru hwemwana masvondo gumi nemana
Pamasvondo gumi nemana, ukuru hwemarefu mapfupa emucheche inenge inotevera:
- femur - 23-31 mm;
- mapfupa erutsoka ruduku - 23-31 mm;
- humerus - 15-21 mm;
- forearm bone is 17-23 mm.
Kukura kwekurera - masvondo 18 ekuzvitakura
Munguva iyi, fetus inoenderera mberi kugadzira meconium - ganda rekutanga, rinosanganisira zvakasara zveamniotic fluid iyo isina kuve yakagadzirwa kuburikidza nekupedza, pamwe chete nemichina yekuvharidzira yegadziriro yekudya. Kutanga kokutanga kwemeconium kunoitika kazhinji mushure mokuberekwa kwomwana. Kana meconium inowanikwa mumamniotic fluid, izvi zvinoratidza hypoxia yakasimba ye fetus - iyo yenzara yekushaya oxygen.
Mukadzi wacho atoona zvakajeka kufamba kwe fetus. Uye anofamba zvikuru - anosunungura maoko ake nemakumbo, anoyamwa zvigunwe, anosvinudza maziso ake nehombodo dzake. Zvose izvi zvinogona kuonekwa pamusana pekukura kwema fetus, inoitwa pamasvondo gumi nemasere.
Pakati pezvinhu zvakakosha zvehutano izvo zvisingagoni kutaridzirwa kune ultrasound, ndeyokukudziridza kwe fetal nerve system. Iye zvino mishonga yake yakafukidzwa ne myelone - chinhu chinokosha chinogonesa kutapurirwa kwemasero emagetsi pakati pemitsipa. Panguva imwecheteyo mitsipa pachayo inowedzera uye yakawanda yakarayirwa, yakaoma uye yakawanda.
Kuwedzera uye kunzwa - kunowedzera kuoma. Kunyange iye zvino mwana anokwanisa kunzwa manzwiro emoyo wemadzimai vangu, huccups yake. Anopindura kumhanya kwekukurumidza nekuzvidya mwoyo, paanenge achikurira zvakaoma uye achirova.
Muhutano dzakadaro nzvimbo dzakanyanya senzvimbo dzekuona, kunwa, kunhuwa, uye kubata kunoumbwa. Newe mwana iwe unogona kutotaurirana, kumuimbira nziyo dzinyararire, urove dumbu rako - iye achazvinzwa nekuda kwako uye achaita sei nazvo. Nzira dzako dzisina kunaka dzinonzwa sei - kutya, kuzvidya mwoyo, kuchema, kuchema. Edza kuti usavaedza, asi ingofarira nzvimbo yako uye upe mwana wako rugare uye rudo.
