Muchikamu chino tichakutaurira pamusoro pezvinhu zvekukura kwema fetal egg uye pamusoro peikukura kwechimiro ichi chinofanira kuva nemavhiki ekudzivirira, uye kupawo tafura iyo inogona kuonekwa maziso.
Tafura yehupamhi hwe fetal egg nemavhiki ekudzivirira
Munzira yakajairika yekugadzirisa nguva yemucheche, ukuru hwema fetal egg inokura nguva dzose uye inenge yakaenzana nematauriro anotevera:
- kusvika masvondo mana kusvika ku5, hupamhi hwemukati hwe fetal egg inenge 4 mm;
- kwemavhiki mashanu kusvika matanhatu kusvika matanhatu, hupamhi hwemuviri hwomuviri uyu hunosvika 6 mm, uye mushure memazuva matatu inosvika pakukura kwayo kusvika pa7 mm inoitika;
- kutanga kubva kumasvondo matanhatu, ukuru hwema fetal egg inowedzera kunyanya zvikuru. Pakati pepakati, panguva iyi yakareba iyo inenge 11-15 mm, asi mune dzimwe nguva inogona kusvika 18 mm;
- kwemavhiki manomwe-8, kukosha kwechiratidzo ichi kunenge 20-25 mm;
- anenge masvondo 8-9 ekudzivirira - 28-33 mm;
- Mavhiki 9-10 - anenge 34-42 mm.
Pakupera kwemavhiki gumi, uwandu hwema fetal yaiwanzosvika 5 cm, uye mushure mekunge nguva ino inoramba ichiwedzera ne 1-2.5 mm maawa makumi mana nemaviri.
Mamwe mashoko akazara pamusoro pemazuva ose ekuwedzera kwehuwandu muhukuru hweiyo fetal yaizobatsirwa netafura inotevera:
Ndinogona here kuziva nguva yekuzvitakura nehukuru hwe fetal egg?
Chimiro uye chiyero chema fetal egg, pamwe nekuvapo kwema embryo mairi, inofanira kutsanangurwa panguva yekuongororwa kwakaitwa ultrasound kuongorora. Kuteerera kune zvose izvi zviratidzo zvakakosha zvikuru, nokuti zvinogona kuratidzira zvose zviri nani kukura kwevana remangwana, uye kuvapo kwekutyora kwakakomba uye kune ngozi.
Kazhinji, uchishandisa tafura iri pamusoro apa, vanachiremba vanoona nguva yekutakura nehukuru hwe fetal egg. Zvechokwadi, iyi nzira haigone kupa mhinduro chaiyo kumubvunzo, apo kubata kwaitika, nokuti mukati maro ye fetal egg inowanzosiyana. Pakati pavhesi, kukanganisa kweiyo nzira yekugadza nguva yekuita gestational inenge mavhiki mashanu kusvika ku2-2.
Ndicho chikonzero chekutarisisa nguva chaiyo yekumirira kwechecheche, kwete chirevo ichi chete chinoshandiswa, asiwo zvimwewo, kunyanya, checcyx-parietal ukuru hwembryo. Mukuwedzera, kana uchitara kuwanda kwemavhiki maererano neetafura inobva paukuru hweiyo fetal egg, zvakare funga nezvehuwandu hweHCG muropa remamangwana amai.
