Ngoko, phawula ukuba ixesha lokukhulelwa lilingana neeveki ezingamashumi amane okanye iinyanga ezili-10 ezincinci, nganye equlethwe iintsuku ezingama-28. Ukubala ukukhulelwa okufanayo kuqala ngosuku lokuqala lohambo lokuya esikhathini. Ngaloo ndlela, ukuphuhliswa komntwana ukususela kwithuba lokukhulelwa kungapheli iiveki ezingama-40, kodwa malunga nama-30 anesibhozo. Kodwa, nangona kunjalo, ekubeni kwakhiwa iqanda elitsha kunye nophuhliso lwalo luqala kancinci, kwaye emva kokuchumisa, ukuphuhliswa kwalo kuqhubeka, ngoko ukubala kuqala ukususela kwinyanga yokuqala.
Kodwa asiyi kuchaza inkqubo yokukhula kweqanda, kodwa siza kuqala "ibali" lethu ngexesha lokuchumisa. Ngoko, emva komzuzu wokuchumisa kwiseli, kukho kuphela iisuclei ezimbini kuphela, ezenziwa iqanda kunye nesidoda. Ukunyuka komnye nomnye, ezi nuclei zidibanisa, ngaloo ndlela zakha i-unicellular embryo, ebizwa ngokuthi yi-zygote.
Ukuphuhliswa kwe-intrauterine yomntu iqulethwe ngamaxesha amathathu: i-blastogenesis (iintsuku eziyi-15 zokuqala), ixesha lokutshatyalaliswa kwentuthuko ye-intrauterine (ngaphambi kweveki yeshumi elinesibini yokukhulelwa ) kunye nexesha lokutshatyalaliswa kwe-intrauterine.
Ngoko, emva kweeyure ezingama-30 ukususela kumzuzu wokuchumisa, isahlulo sokuqala se-zygote senziwa. Kwiintsuku ezilandelayo, kuphinda kuhlulwe esinye isahlulo. Ngomhla wesine, xa umntwana, njengomthetho, afinyelela kwisibeleko, yinto enamaqela angama-8-12. Kwiintsuku ezintathu ezalandelayo, umbungu uyangena kwi-uterine, kwaye apha inkqubo yokwahlukana ihamba ngokukhawuleza. Ngaphakathi kweyesithandathu umhla umbungu unamaqela angaphezu kwekhulu. Malunga nomhla wesixhenxe umbungu ulungele ukufakelwa kwisigumbi sokubeletha esilungiselelwe ngexesha elifanayo, esiyi-medium medium evolved and thickened. Kuthatha malunga neeyure ezingama-40 ukufaka imbryo! Ekupheleni kweveki yesibini yokuphuhliswa kwe-intrauterine, inxalenye engaphantsi kwe-embryo iyancipha, kuba inkqubo yokubeka i-orxial organ starts in it.
Ekupheleni kweveki yesine yokukhulelwa, uyazibuza ukuba kwenzekani kwinyanga yonke ... Ngoko ke, kukho iziganeko zokuthi ukhulelwe. Abanye besetyhini baziva imeko yabo entsha intuitively kancinci ngaphambili. Ngenxa yoko, i-malaise kunye neengxondorha zingabonakala, kunye nokwanda kwondlo okanye umnqweno wokutya into engavamile. Usana lwakho selusekho ngosuku lwesithathu emva kokuqumba kokuqala ukuvelisa iHCG (i-chorionic gonadotropin). Yonke imvavanyo yokukhulelwa evelele kule hormone. Kwiintsuku ezi-10 ukuya kwele-14 emva kokuchumisa, izinga le hormone likhuphukela kumda wobuchule bale mvavanyo. Ngeveki yesine umntwana ozayo (zygote) uba ngumbungu. Ekupheleni kweli veki, umntwana ufikelela kwisayizi ye-0.4-1 mm, ubungakanani beesanhlamvu ezincinci zesanti.
Ngeveki yesihlanu unokuqala ukuziva ukhathala okwandayo, ukwandisa uvakalelo lweentlanzi zamathambo. Ukuba isonto elidlulileyo umntwana uqulethwe ngeendlela ezimbini zeeseli, i-endoderm kunye ne-ectoderm, kwaye le veki iya kufakwa yesithathu-mesoderm. Kwixesha elizayo, i-ectoderm iya kuba yinkqubo yesantya, isikhumba, iinwele kunye ne-tooth e-mail. I-Endoderm iya kuphuhlisa ibe yindlela yokutya. I-Mesoderm iyisiseko samagulane, isisipha, igazi, iinkqubo zokuzikhusela nokuzala. Ekupheleni kweveki, iseli ye-nervous isivele ibonakala kwi-ectoderm, kunye ne-mesoderm - intambo ye-dorsal. Ukongezelela, ityhubhu yenhliziyo ifakwe. Ngemuva kwembungu, i-groove yenziwe, eyayihlanjululwayo, iyajika ibe yimboyi ye-neural. I-tube ye-neural kwinkqubo yophuhliso iba yinto, kunye nentambo yomgogodla kunye nenkqubo yesantya yonke. Ngako oko, kubaluleke kakhulu ngokukhawuleza kwangoko, nangona kwinqanaba lokucwangcisa ukukhulelwa, ukuqala ukuthatha i-folic acid, ekhuthaza ukusekwa okukhuselekileyo kwiphubhu yomntwana.
Isikhwama, i-embryo ngokwayo kunye nemimbrane ejikelezayo kunye ne-liquid ifana nesentimitha enye. Umntwana wakho ozayo uhlala kwi-1.5 mm kuphela kule ndawo encinane.
Abesifazane abaninzi ngeveki yesithandathu yokukhulelwa okokuqala ngqa batyelela umfazi wezinja ukuze baqiniseke "ngolu hlobo". Ukususela kwiveki yesithandathu iqala ixesha elibalulekileyo lokubeka kunye nokwenza izakhiwo zangaphakathi nezangaphandle zomntwana - organogenesis. Iphela kwiveki yeshumi, nangona, ngokwenene, ukuphuhliswa kwezitho zangaphakathi zentsana kuya kuqhubeka ngokuqhubekayo emva kokubeletha. Ngeveki yesithandathu umntwana uthatha isimo se-C. Le veki kukho amagatsha amancinci - ezi zixhobo kunye nemilenze yengomso, kunye nekhanda eliqhelekileyo kunye nemikhosi evelele kunye ne-thickenings, apho amehlo, indlebe kunye ne-spout ziya kuphuhliswa. Ngeveki yesithandathu, izitho ezininzi kunye nezicubu zomntwana wakho zibekiwe: isisu esisisiseko, amaqhekeza amathambo kunye neengqungquthela ze-axial squke, i-thyroid gland, iinjongo, isibindi, i-pharynx, kunye nezihlunu ezixhatshazayo kunye ne-squax. Ekupheleni kweliveki, ukuphela kwentloko ye-tube ye-neural ivala. Okwangoku ngoku umntwana wakho unobunzima beerayisi - i-4 millimeters. Intliziyo yakhe ibetha kwaye ibonakala ngokucacileyo nge-ultrasound.
Ngeveki yesixhenxe yokukhulelwa, abaninzi abafazi baqala ukuvakalelwa kwandiso lwe-nausea ekuseni, kwaye baphendule ngokukhawuleza kwiimpume ezahlukeneyo.
Ngeli xesha, intloko ikhula ngokukhawuleza ngenxa yokuphuhliswa okusebenzayo kwengqondo. Intloko ijikelezwe, iziseko zeso zibonakala. Umlomo uqala ukwenza. Kukho uphuhliso olusebenzayo lwenkqubo yokuphefumula yomntwana: izibonda ekupheleni kwetrachea ezixhamlayo zibe ngamasebe ezinqabileyo, eziza kuhlakulela ukuya kwi-bronchi ekunene nasekhohlo. Intliziyo iqala ukuhlukanisa ngamagumbi kunye nemithambo. Imifuno ivela, ifomu le-gallbladder kunye ne-spleen. Umntwana wakho sele sele efikelele kwisayizi se-pea, i-8 mm!
Ngeveki yesibhozo yokukhulelwa, ungasebenzisa i-ultrasound ukulandelela ukuhamba kokuqala komntwana wakho. Ngeli xesha, i-auricles, spout kunye nomlomo ophezulu sele sele uvela. Kukho izandla kunye neminwe kubo, kodwa izitho ezingezantsi ziza kuphuhlisa kamva. Ekupheleni kweliveki, imbungu ibude obude be-13 mm, xa ilinganiselwa kwisithsaba sekhanda ukuya kwisiseko senkomo. Olu bukhulu luyi-prawn echibi.
Ngeveki yesithoba , iinguqu eziphambili kwiingalo nasemilenzeni ziyakubonwa. Iminwe imiselwe, nangona kunjalo, isancinci, inqabile kwaye ikhunjulwe. Amagqabi amelwa ngamathambo enqabileyo, kodwa ukwakheka kweethambo zethambo kuqala kwiingalo. Ngokuhlolwa kwe-ultrasound, unokwazi ukuguqa kwamadolo kunye neengqungquthela, njengokungathi umntwana uyabanika. Ngeli xesha, iinkophe zivela, intamo iqhutywe, intloko ayikho enye efana neyokuqala, icinezelwe kwisifuba. Kancinci, indima ye-placenta iyaqulunqwa: inika ukutya kokusana okuvela kuwe kwaye ikunika iimveliso zentengiso yomsebenzi obalulekileyo. Umntwana wakho ukhulile kakhulu, ngoku ubude bakhe bu-18 mm, njengamantongomane.
Iveki yeshumi yokuphuhliswa kwe- intrauterine yiveki yokugqibela yexesha lokubambiswa kwe-intrauterine. Emva kweveki kuze kube sekuzalweni ngokwaso, umntwana kwisigama sesigxina kuthiwa ngu-fetus, kodwa oku kuogqirha. Kuba kuthi, uvela kwangoko umntwana, inkunzi kunye nenye into ...
Ngeli xesha, iminwe ehlukeneyo ngenxa yokunyamalala kweembrane phakathi kwabo. Kuyacaca ngokunciphisa, kwaye ekuqaleni kweveki yeshumi elinanye iyanyamalala ngokupheleleyo, umsila. Umntwana ufumana ubuso bomntu. I-genitalia yangaphandle isabonakali, kodwa abafana sele beqala ukuphuhlisa i-testosterone.
Iveki yeshumi elinanye. Ngoku inhloko yomntwana ilingana noqingatha ubude bomzimba wakhe. Amehlo omntwana asasazwa ngokubanzi, iindlebe ziphantsi, kwaye imilenze isancinci kakhulu xa ifaniswa nobude bomzimba. Ukususela kwiveki yeshumi elinanye, iintso ziqala ukusebenza: zivelisa umchamo. Isibindi ngoku senza u-10% kwisisindo somzimba wonke. Ubude bomntwana bu-5 cm kunye nobukhulu be-8 amagremu.
Kukholelwa ukuba sele sele ivela kulo xesha lokuphila kwangaphambi kokubeletha umntwana uvakalelwa kakhulu oko umama azizwayo. Ezinye iingcali zithembele kwimbono yokuba "iziseko zomntu sele zibekiwe".
Iveki yeshumi elinesibini yithuba apho umntwana ozayo sele esele esakhelwe ukukhula okuqhubekayo nophuhliso. Kwakukho ibhukumaka yazo zonke izitho kunye neenkqubo-eyona nqanaba eliphambili lophuhliso lwe-intrauterine. Izitho zomzimba zesini kunye namabhinqa ziya kwahlula kuphela emva kweveki ezimbalwa. Nge-ultrasound, ungayigcina loo "maqhinga acrobatic" ayenzayo. Kwaye akumangalisi: umntwana usebenza kakhulu, kodwa kusekho indawo ezininzi zokuhamba. Ukukhula komntwana ekupheleni kweli veki kuku malunga no-6 cm kunye nobukhulu-14 amagremu. Kwaye akukho ubukhulu bepea encinane, kodwa inkukhu enkulu yenkukhu!
Iveki yeshumi elinesithathu yiveki yokugqibela yekota yokuqala yokukhulelwa. Le veki intlungu yomntwana ikhona ngokupheleleyo kwisibilini esiswini. Umntwana uziva kakhulu kummandla wamanzi - i-amniotic fluid. Isondlo kunye ne-oksijini ayifumana ngentambo yomthamo kwisixa esaneleyo sokukhula nophuhliso. Ubude bomntwana bu malunga no-7 cm, kwaye ubunzima buyi-30 gram.
Ngeveki yeshumi elinesine, i- cartilage, apho i-skeleton yengomso yomntwana, yayiphenduka ibe ngamathambo. Izandla zinobude obulinganayo nobude bomzimba, kodwa imilenze ekukhuleni kwayo isalahlekile emva kwayo. Umntwana sele sele ekhwelisa kwaye enamunwe ngomnwe, kwaye uyawa. Ubude bomntwana bu malunga no-8.5 cm, ubukhulu-45 grams.
Iveki yeshumi elinesihlanu. Umthamo wokunyakaza kweengcambu zomntwana uba mkhulu kakhulu kunexesha elidlulileyo lophuhliso. Ikhumba lomsana lomntwana ludlulisa imithwalo yegazi emicinci. Izibambo zinyanzelisiwe zibe ngamanqindi amancinci. Amathambo ayaqhubeka nokukhula, kunye nomnatha wethambo. Ubude bomntwana ngu-10 cm kwaye bunzima i-78 gram.
Ngeveki yeshumi elinesibhozo ngoncedo lwe-ultrasound, unokwazi ukubona indlela umntwana ehamba ngayo amehlo akhe. Intloko igcinwe ephakamileyo ngenxa yokuba intamo ikhule kakuhle. Izindlebe sele zisesigxina sabo sokugqibela, amehlo abo aya kutshintshwa kwiziko. Le veki, imilenze ibe yelingana nobude bomzimba. Qala ukhula i-nogatochki encinane. Usana lunesisindo sika-110 grams, ubude balo buyi-12 cm.
Iveki yeshumi elinesixhenxe. Umzimba womntwana uhlanganiswe ne-primarygo flugo -gogo. I-lubricant yasekuqaleni, eveliswa ngeengqungquthela ezikhethekileyo, ikhusela ulusu lomntwana kummandla wamanzi. Le veki, isiseko seminwe yeminwe ezayo, echazwe ngokusemthethweni, isetyenziswe. I-placenta izalisekisa ngokusemthethweni umsebenzi wayo oyintloko: inika umntwana nge-oksijini kunye nesondlo kwaye ithatha imveliso yezinto eziyimveliso ebalulekileyo. Ekupheleni kweveki umntwana ukhula u-13 cm kwaye ulinganisa malunga ne-150 grams.
Iveki yeshumi elinesibhozo . Umntwana wakho usemncinci kwaye uncinci, amafutha angaphantsi angakabonakali. Nangona kunjalo, yonke imihla, zonke iimpawu zobuso zibonakala ngokucacileyo. Usana sele selukwazi ukuva izandi ezivela kumanzi amniotic, nangona uvaphula ngokungafaniyo. Okwangoku, inani lemibuzo yamathambo, i-ovaries ezayo, kwiiyunithi zamantombazana zi malunga nezigidi ezi-5, kodwa eli nani liza kuncitshiswa libe yizigidi ezi-2 ngokuzalwa, kwaye inxalenye encinane yale nombolo iya kukhula ngexesha lobomi.
Ubude bomntwana buyi-14 cm kwaye bunzima 200 amagremu.
Ukususela ngeveki elishumi elinesithoba ekukhuleni komntwana kuqala ukuhla kancane kancane. Ngoku inkqubo yokubeka i-fat-cutaneous begins, eyenziwa njengomthombo obalulekileyo wokushisa intsha. Ukuphuhlisa imiphunga, ukhule i-bronchioles, kodwa ixesha lokuba inkqubo yokuphefumula yomntwana ayikwazi ukusebenza ngaphandle koluncedo lomzimba kamama.
Nangona ukuba amehlo omntwana avaliwe, sele sele akwazi ukuhlukanisa ukukhanya ebumnyameni. Ekupheleni kweli veki, umntwana usukhule ufike kwi-15 cm kwaye ulinganisa u-260 amagremu.
Iveki yeshumi. Umntwana wakho sele esazi ukunyunyuza, ukunamathela ngomunwe, ukudlala ngentambo yomgca, kunye namakhwenkwe akwazi ukudlala neepenis. Amantombazana asele ayenze i-uterus, ibhinqa isesigxina sesakhiwo. Ngoku umntwana ulinganisa iigremu ezingama-320 kwaye ubude buyi-16 cm.
Iveki engamashumi amabini anesibini ekuphuculweni kwe-intrauterine. Ingane inokugwinya i-amniotic fluid. Iingqungquthela zobisi kunye namagxina asisigxina sele zenziwe. Ukunyakaza komntwana kuya kusebenza ngakumbi. Usana lukhule lwaba ngu-17.5 cm kwaye lunzima u-390 grams.
Iveki engamashumi amabini nesibini. Usana luyaqhubeka lukhula iinwele entloko yakhe, kubonakala ukugqithisa. Ingulube ejongene nombala weenwele, iza kuqala ukudala kamva. Oomama abaninzi sele beziva ukunyuka komntwana. Ubunzima bomntwana ngu-460 amagremu, ukuphakama - 19 cm.
Iiveki ezingamashumi amabini ezithathu. Ukuba ngaphambili umntwana wakhula kakhulu, ngoku uyaqala ukwandisa ukunyusa. Umntwana ubona amaphupha. Oku kuboniswa ukuhamba ngokukhawuleza kwamehlo, ukukhumbuza isigaba sokulala esisebenzayo kumntu omdala. Ndiyabulela kule ntshukumo esebenzayo yamehlo, ukuphuhliswa kwengqondo kukhuthazwa. Ukuba uphulaphule isisu esisulelwe nge-tube, ungayiva intliziyo yesana. Ngoku umntwana usenomyinge we-540-550 amagremu ngokuphakama kwe-20 cm.
Iiveki amabini anesine. Inkqubo ye-muscular kunye nezitho zangaphakathi zomntwana ziphuhliswa. Ukuba umntwana uzalwe ngoku, uya kusebenza, nangona uya kufuna iimfuno zokuhlala ezikhethekileyo. Kuze kube ngeli xesha, imiphunga ayizange isebenze okwamanje, kodwa ngoku iinqununu zogqitywa zenziwa kwiiphelo ze-capillaries, ezahlukana nefilimu encinane evela kwi-alveoli. Ngoku, umntu oqhagamshelana naye, oqhagamshelana nomsebenzi, uveliswa, ngenxa yokuba ifilimu encinci yenziwe kwiindonga zamathambo e-capillary, kutheni abangenamathele ndawonye phantsi kwefuthe lokuphefumula.
Umntwana wakhula waba ngu-21 cm kwaye ulinganisa u-630 amagremu.
Iveki engamashumi amabini anesihlanu. Ngomathumbu wengane, iifesi zangasese ziyaqhubeka zize ziqokelele, ezibizwa ngokuba yi-meconium. Ukuba unengqondo, ukunyuka kwengane kunokusenokuzivelela ngabangaphandle, ukubeka isandla kwisisu sakho. Ubude bomntwana sele bufikelele kwi-28 cm, kwaye ubunzima buyi-725 grams.
Iveki engamashumi amabini anesithandathu. Ulusu lolusana lube lubomvu kwaye lubomvu. Nangona i-fat-cutaneous fat continues to accumulate, umntwana usaluncinci. Ngenxa yobukho be-amniotic ngokwaneleyo kunye nobukhulu obuncinane bomntwana, bukwazi ukufuduka. Umntwana usabela kwizandi zangaphandle, kunye neenguqu kwiimeko zomzimba womama. Ulwimi lusele lusele i-taste buds, ngenxa yokuba sele sele ikhona kweli nqanaba lokuphuhliswa kwe-intrauterine ukukhetha okukhethwa kwintlobo ethile, ngokomzekelo, uthando lomnandi. Ngoku umntwana usinda malunga ne-820 amagremu kwaye unokuphakama kwama-23 cm.
Iveki ezingamashumi amabini anesixhenxe. Oku kukuqala kwekota yesithathu yentuthuko ye-intrauterine yendoda encinci. Zonke iinkqubo zesebe sele zenziwe kwaye zisebenza ngokusebenzayo, ngexesha elifanayo ziyaqhubeka nokuphuhlisa ngokufanelekileyo kwindawo efanelekileyo. Iinyanga ezidlulileyo ezintathu zithuba lokukhula okukhulayo nokuphuhliswa kwengqondo yomntwana.
Iveki engamashumi amabini anesixhenxe. Umntwana ngeli xesha lokukhulelwa sele sele likhule ukuya kwi-35 cm! Ngoku i-900-1200 gram. Ngenxa yokuba izicubu ezinamafutha angaphantsi komntwana zisaphilile kakuhle, isikhumba sakhe sinobonakala obunzima. Umzimba wonke wengane uhlanganisa iinwele zeenja. Kwaye kwentloko, iinwele zifikelela ubude be-5 mm. Iifutshane zabantwana zithenda kwaye zithenda. Maxa wambi umntwana ovula amehlo akhe. Ngamakhwenkwe, ngeli xesha, amacwecwe avela kwisisu esisiswini asikaze afike esiqwini, kwaye amantombazana anemibhobho enkulu engakhange ihlanganiswe nabancinci.
Iveki engamashumi amabini anesithoba. Uqala ukusebenza nokuphuhlisa umzimba womzimba womntwana. I-Enamel ibonakala kwiintsholongwane zamazinyo ezizayo. Ubungakanani bentsholongwane yenhliziyo yengane i-120-130 ibhokhwe ngomzuzu. Umntwana uhlamba, ngelixa umama evakalelwa ngumsindo. Umntwana ozelwe ngeli xesha angaphila ukuba kukho imeko efanelekileyo. Usana lukhule luya kuma-37 cm kwaye lunzima u-1150 g.
Iveki yeshumi. Ingane iyayazi indlela yokusabela ekukhanyeni okukhanyayo okukhanyayo ngesisu. Imiphunga yomntwana iyaqhubeka nokuphuhliswa, ngenxa yo "kuphefumula" kwesifuba. Ngoku umntwana ulinganisa malunga ne-1300 g kunye nokwanda kwe-37.5 cm.
Iveki-eveki yokuqala. Uluhlu lwamanqatha phantsi kwesikhumba luba lukhuni, ngoko isikhumba sekhanda asisekho njengamanzi njengamaxesha adlulileyo. I-membrane yepupilla ayikho. Ezinye iintsana sele zijikezele ikhanda phantsi kweli xesha. Ingane ikhule ibe ngu-39 cm kwaye ilinganisa 1.5 kg!
Iveki yesibini nesibini. Zonke iistim kunye nezitho ziqhubeka nokuphuhlisa, kubandakanywa nenkqubo yesifo somntwana. Amacembe avela ebusweni bobuchopho. Abafundi banako ukunciphisa kwimeko yokukhanya okutshatyalaliswayo ngesisu somama.
Iiveki engamashumi amathathu nesithathu. Kule nqanaba lokuphuhliswa kwe-intrauterine kwisisu somama kukho indawo eyaneleyo yokunyakaza, kodwa nantsi into encinci, kwaye iya kuba yinkimbinkimbi kakhulu. Ingane isele iphendule intloko yayo, njengoko kungekudala kungekuze kubekho indawo eyaneleyo yokwenza i-somersault ebalulekileyo "yokuphuma". Umntwana unokuphakama kwe-41 cm kunye no-1900.
Iveki yesine neyesine. Ukuba ngokukhawuleza kukho ukuzalwa kwangaphambi kokuzalwa, umntwana uza kuzalwa asebenze, kodwa uya kuthathwa njengengaphambi kokudala kwaye afune unonophelo olulodwa lwexesha elide. Iiveki ezintandathu eziseleyo zokuphuhliswa kwe-intrauterine ibakala elibalulekileyo ekulungiseleleni ukuzalwa.
Ulusu lomntwana seluqhelile kwaye lulophuzi, ngenxa yokuqokelela kwamanqwanqwa angaphantsi, okwangoku angama-8% omlinganiselo womntwana. Usana lukhule ngo-43 cm ubude kwaye lunzima u-2100 g.
Iiveki ezingamashumi amathathu anesihlanu. Umntwana uye wakhula i-marigolds, kwaye unokukwazi ukuziqhayisa. Ezinye iintsana zizalwe zizalwe. Umntwana uyaqhubeka nokunyusa. Ngoku ulinganisa i-2300 g ngokunyuka kwama-44 cm.
Iveki engamashumi amathathu nesithandathu. Umntwana, njengomthetho, wawa phantsi. Ukuba akazange akwenze oko, akunakwenzeka ukuba uya kukwazi ukukrazula. Izinwele ze-Pushkin emzimbeni onqabileyo, kodwa iinwele entloko zandisiwe. Iinqwelo zeendlebe zeendlebe kunye ne-spout ziyahlanganiswa. Amaqanda amakhwenkwe asele e-scrotum. Ubukhulu bomyinge womntwana ngu 2.5 kg kunye nobude buyi-45 cm.
Iiveki ezingamashumi amathathu nesikhombisa. Phuhliso imiphunga ihamba ngokugcwele, yonke into ilungele ukuphefumula ngokuzimeleyo. Umntwana ufumana ama-grams angama-30 ngosuku. Umntwana ozelwe ngeli thuba lokukhulelwa angakhwaza, ukutshatyalaliswa kunye nokutsala okuyiyo. Ngoku kufuneka aqikelele umlinganiselo we-2700 g ngokuphakama kwe-46 cm.
Iveki engamashumi amathathu nesibhozo. Umntwana ulungele ukuzalwa. Ukuba uthe wazalwa ngalo mhla, ngoko-ke uya kubala u-2900 grams kwaye abe nokuphakama malunga ne-48 cm. Ngalesi sikhathi, umntwana usoloko ehla enkundleni ye-pelvic, kwaye uvakalelwa kukuba kukuva ukuphefumula okungcono.
Iiveki engamashumi amathathu nesithoba. Ingane yakho emathunjini isele ixinile, amadolo akhe axinzekile. Izinwele zasePushkoe zahlala kuphela kwindawo yokubhinqa. Intloko yomntwana ihlanganiswe ngeenwele ezinokufikelela kwi-2-3 cm ubude. Ukuphakama kwengane ngu-49 cm, kunye nobukhulu buka-3150 g.
Iveki eveleleyo. Ukunyakaza komntwana kuncitshiswa ngexesha lokuzalwa. Iingqayi zebhokhwe zixutywe nge-meconium, iifesi zangasese eziluhlaza okomnyama, ezi ziyi -gogo, izilinganiso zesidumbu, i-amniotic fluid - yonke into eyigxile kwinkqubo yophuhliso lwangaphakathi. Ubunzima bemyinge yexesha elizeleyo eliza kuzalwa li-3-3.5 kg, kwaye ubude buyi-48-52 cm.
Ngoko "sidlulile" kunye nawe i-odyssey engaqondakaliyo kunye nokuthakazelisayo yokuphuhliswa kwe-intrauterine yomntwana kwiiveki. Ukususela kwiseli elincinci kwiinyanga ezithoba, indoda encinci ekhulayo ivulekele - uvuyo olukhulu kumama noyise. Inhlanhla, umntwana, inhlanhla!
