Inyanga yokuqala yokukhulelwa: ukuthuthukiswa kombungu wamaviki nezinsuku esithombeni nakwividiyo

Abaningi besifazane ngenyanga yokuqala yokukhulelwa abazi kahle ngesimo sabo esithakazelisayo. Ukuma nobukhulu besisu akuguquki. Kodwa-ke, yonke imetamorphoses kuleli gama ingaphakathi, hhayi yangaphandle. Ukuthuthukiswa kombungu kuhamba ngezigaba eziningana. I-embryo ihamba kancane kancane, ishintsha njalo ngesonto. Ngeke ukwazi ukulandelela ngokuzimela, kodwa kulula ukucabanga ngezithombe ukuthi impilo entsha izalwa kanjani.

I-embryo, i-embryo, noma i-fetus: iyakha kanjani

Isikhathi sokubeletha sibalwa kusukela ngesikhathi sokuya esikhathini sokugcina. Kulesi simo, ukukhulelwa kanye nokuvuthwa kwangaphambili kwenzeka cishe ezinsukwini ezingu-14 kamuva. Isonto lokuqala likhishwa ukugeleza kokuya esikhathini. Kulesi simo, umzimba wesifazane ulungiswa esikhundleni sakhe esisha. Emaqanda amaningi, u-1 kuphela uqala ukuvuthwa. Ubuso obunamaqabunga obubeleko buthakathaka kancane kancane. Amafomu esendlalelo esisha kusayithi lezicubu ezilahliwe. Njengalokhu, akukho embryo okwamanje. Ngisho naku-ultrasound akusi njalo ukulandelela lezi zinguquko.

Isigaba sesibili sibonakala ngokubonakala kweqanda, okungathiwa umholi. Igxile enhlobonhlobo ye-bubble ekhona kwi-ovary. Ukuphela kwalesi sigaba ukugeleza kwe-ovulation. I-vesicle bursts, emva kwalokho iqanda ngokwayo lishiya isisu somzimba wesifazane. Futhi, akukwazi ukubizwa ngokuthi izithelo, ngoba isakhiwo esincane kakhulu, njengoba siboniswa esithombeni, singena emgodini we-fallopian. Ngezinsuku ezingu-1-2 umntwana ozayo uzogcinwa lapho. Emva kwalokho, kuhlale nje ukulinda i-spermatozoa. Kunezinhlelo eziningi zamavidiyo mayelana nokuthi "umhlangano" wabo uvela kanjani. Ngezansi omunye wabo.

Ukuthuthukiswa kwe-fetus: izithombe ezinsukwini zakhe zokuqala

Kuze kube izinyanga ezimbili, ukukhulelwa kubizwa ngokuthi i-embryonic, ngoba ingane isesimweni sombungu. Ukuthuthukiswa kombungu, okungahle kulandelwe ngezithombe ezinikezwe nezithombe, kusho umhlangano we-ovum nesidoda. Umphumela wokuxhumeka kwawo yindawo ephuzi, ebaluleke kakhulu ngenyanga yokuqala.

Encwadini! Kusemkhawulweni ophuzi ukuthi i-estrogen ne-progesterone ikhishwa, okuyiyona enomthwalo wokulondoloza ingane.

Ukusebenza kwalo mzimba kuhlotshaniswa ne-toxicosis. Ngokuvamile, ngemuva kokuba yonke imithwalo yemfanelo yokulondoloza ingane yesikhathi esizayo idlulela ku-placenta, zonke izibonakaliso ezingathandeki ezinyangeni zokuqala zesimo esithakazelisayo sidlula. Le nqubo ihlotshaniswa namaviki angu-14-16.

Ngokuqondene nezimo eziphawulekayo zenkambo yezimo ezithakazelisayo ezinsukwini ezingu-15-28, zihlotshaniswa nesingeniso sombungu ebusweni obukhulu bendwangu yamangcwaba ye-uterine cavity. Ngesikhathi esifanayo kwi-ultrasound, kulula ukulandelela imingcele yengane ezayo.

Ama-embryo wesithombe amaviki: amasonto angu-1 nama-2

Nsuku zonke zesikhathi semibryoni siyathandeka. Phela, umbungu uthola izici ezikhethekile kumntana wangempela, naphezu kokuthi isisu, njengombuso, ubukeka njengangaphambili futhi singanikeli impilo entsha evela kuwo. Isonto lokuqala lihlotshaniswa nenqubo yokukhulelwa. Kukhona ukuhlanganiswa kweseli lesifazane nesidoda. Njengomthetho, konke kugeleza ngaphakathi kwe-tube fallopian, emnyangweni wayo we-ampullar. Kuvidiyo engezansi ungakwazi ukulandela okuvelele kokusuka kombungu.

Nakani! Amahora ambalwa kuphela ezinsukwini ezingu-1-7 anele iseli lesifazane elikhulelwe ukuba lihlukanise ngesivinini esikhulu ekuthuthukisweni kweJiyomethri, emva kwalokho kungena kwesibeletho ngokusebenzisa i-tube fallopian.

Ngemuva kokuhlukaniswa, kwakhiwa isakhi esikhethekile. Ngaphandle, kubonakala into efana ne-blackberry, njengoba ungabona kwenye yezithombe. Kulesi sigaba, umthambo wesifo sokubeletha uvame ukubizwa ngokuthi i-morula. Ngosuku lwesikhombisa, ivame ukufakwa esibelethweni. Amanye amangqamuzana enza i-membrane ne-umbilical cord. Kwamanye amangqamuzana, izitho zangaphakathi nezicubu ze-fetus zizoqhubeka. Iviki lesibili lenyanga yokuqala yokukhulelwa kuboniswa ukufakwa okunamandla kwe-morula ngaphakathi kwesikhumba esiswini sombeletho. I-fetus iqala ngezinsuku 8-14:

• i-placenta;
• intambo ye-umbilical;
• i-neural tube.

Isithombe sezingane esiswini ngezinsuku: amaviki amathathu nesine

Naphezu kokuthi isisu ngesonto lesithathu lokukhulelwa libukeka, izinsuku ezingu-15-21 ekuthuthukisweni zibaluleke kakhulu. Lesi sigaba sihlotshaniswa nokwakheka kwezingxenye zezinzwa ze-nervous, circulatory, respiratory, excretory, digestive. Esikhathini isithombe ungabona ukuthi ingane ezayo ibukeka kanjani. Amafomu e-plates amaningi. Kule ndawo lapho ingane ingaba nekhanda ngokuhamba kwesikhathi. Usuku 21 luqala ukuthuthukiswa kobuchopho hhayi kuphela.

Encwadini! Kulesi sigaba senyanga yokuqala yokukhulelwa, inhliziyo iyaqala ukushaywa.

Iviki 4 ngesithombe nencazelo

Ezinsukwini ezingu-22-28, njengoba zikwazi ukwahlulelwa esithombeni nakumavidyo, i-fetus ibonakala ngokucacile kwi-ultrasound. Isikhathi sihambisana nokuqhubeka kwebhukimakhi kanye nokuthuthukiswa kwezitho. Kukhona izici:

• ukukhanya;
• isibindi;
• izinso;
• umgogodla.

Inhliziyo iqala ukusebenza ngenkuthalo. Kukhona amafolda e-trunk, futhi ngosuku lwama-25 i-neural tube yenziwa ekugcineni.

Ekupheleni kwesikhathi sokuqala sokuvuselelwa komzimba wesifazane, umgogodla kanye nesimiso semisipha zakhiwa. Futhi ama-dimples avela ekhanda, kamuva abe amehlo.
