Nsuku zonke isisu somfazi okhulelwe sikhula, kwaye ngokufanelekileyo, umntwana oza kutsalwa uza kuzalwa ukhula. Yonke imihla ayidluliyo-iyakhula, imilenze, izitho zikhula, izipikili, amazinyo kunye neenwele zivela. Ukwamukelwa "ukukhula" komntwana kuthathwa njengeiveki. Ngoko, imimmies, iveki emva kweveki, zihlala zikulindeleke, zilawula ukuphuhliswa ngoncedo lwe-ultrasound kunye nazo zonke iintlobo zokuhlalutya.
Umbungu kwiiveki ezingama-19 ubudala
Makhe sibone ukuba yintoni i-embryo enokuyenza kwiiveki ezingama-19, yintoni impawu enayo, yintoni ubungakanani kunye nobukhulu bomntwana obusweni kwiiveki ezingama-19. Njengomthetho, kwi-trimester yesibili, ngeveki yesi-14 ukuya ku-26 kuyacetyiswa ukuba ufumane i- ultrasound ye-fetus . Nge-ultrasound kwiiveki ezingama-19 zokukhulelwa, kuyacaca ukuba indawo yomntwana engagqitywanga, kuba ihlala ishintsha isikhundla sayo, kwaye le nto ivakalelwa kakuhle ngumfazi.
Iiveki ezingama-19 zokukhulelwa - ubukhulu bomntwana
Ubukhulu bomntwana ngeveki 19 buya kwanda. Sinika ixabiso eliqhelekileyo le-fetometry (ubungakanani) bomntwana wesibhozo ezingama-19 ngee-ultrasound ngokuqhelekileyo:
- ubungakanani biparietal (iiveki ze-BPR ezingama-19) ngu-41-49 mm;
- ubungakanani be-occalital (LZ) buyi-53-63 mm;
- Umda we-headal fetal (OG) u-142-174 mm;
- umjikelezo wesisu esiswini (OJ) si-114 -154 mm.
Ngeeveki ezingama-19 zesisu, ubunzima bomntwana obushushu bungama-250 g, ubungakanani bepricetal parietal malunga ne-15 cm.
Yintoni isiqhamo kwiiveki ezingama-19?
Kule minyaka, umntwana sele sele edale ixesha lokulala nokuvuka, kwaye bahambelana nolawulo lwentsana - iintsuku ezingama-18 zokulala zifaka iiyure ezingama-6 zokuvuka. Imihlathi yakhe ibunjwa, kukho iindawo ezinokwakheka kwamanzi kunye namazinyo asisigxina. Kwi-ultrasound, uyabona indlela umntwana ekhupha ulwimi lwakhe aze avule umlomo wakhe. Ngalesi xesha umntwana sele sele ekhuselekile ngokuphakamisa intloko kwaye angayijika. Iminwe ezandleni zinyathela imilenze, intambo yomlomo - ngoko umntwana ufunda indawo yakhe yokuhlala.
Ubungakanani besisu ngesonto eli-19 lokukhulelwa
Kwiiveki ezi-19 ukuya kwe-20 phantsi kwe-uterus ikhona kwiminwe emibili ejikelezayo engezantsi kwintonga. Iqhubeka ikhula kwaye iphakama phezulu, ubunzima besibindi kwiiveki ezingama-19 zi malunga ne-320 g. Ingabinwe kwizinga le-1.3 cm ngaphantsi kwendoda. Ngeli xesha, isisu sele sakhulile kakhulu; inokubonwa ngeso lesiso, nokuba likhulelwe kwiingubo. Ubungakanani besisu ngesonto le-19 landa kakhulu, malunga ne-5 cm ngeveki.
