Ubufakazi bokuthi umntwana unamandla kaningi kunomama wakhe, ashaqele noma ubani ...
Isimiso sokubeletha sitshela abesifazane ukuthi izingane zingabantu abanobuthakathaka futhi ngakho-ke zidinga ukunakekelwa nokuvikelwa njalo ezweni elingaphandle. Kodwa-ke, isayensi isicabanga ngendlela ehlukile: ngokuqinisekile, ososayensi ngeke batusa ukuba bahlole ukutholakala kwabo ezinganeni zangempela, kodwa akungabazeki ukuthi baqinisile.
1. Uma ubeka ingane esiswini sikamama, uyasiphuza esifubeni sakhe ngaphandle kosizo
Akukhona nje omama abancane, kodwa futhi izingane zabo ziphazamiseka yizinkanyezi ezinikezwe imvelo ngokwazo. Izinsana ngokwazo zidonsa esiswini sikamama, ngoba ziyakhangwa iphunga lezinsipho - "uphawu" olunamandla kunawo wonke olwaziwa kubo. Kufana nephunga le-amniotic fluid lapho umntwana esesiswini, ngakho kuhlotshaniswa nokufudumala nokududuza. Ngendlela, uma i-amniotic fluid isala ezingalweni zomntwana, uqala ukuncelisa iminwe yakhe.
2. Iningi lezinsana likwazi ukudoba nokudilika
Amaphesenti ama-95% ane talenta yokuzwa emanzini akubi nakakhulu kunomhlaba. Ngesikhathi sokubhukuda, inani lezinhliziyo liyancishiswa ngama-20%, futhi ukugeleza kwegazi kwehla - lezi zinguquko zibonisa ngokucacile ukuthi ingane ayesabi amanzi. I-Dive reflex isisiza ukulondoloza umoya-mpilo ngenhliziyo nangokwengqondo, abantu abadala abadobayo abafundela iminyaka. Lekhono lisiza ingane ukuba iphile isikhashana ngaphansi kwamanzi. Kodwa okumangalisa nakakhulu ukuthi ngemva kokufinyelela ezinyangeni ezingu-6, wonke amakhono angenhla aphahleka ngokuzumayo.
3. Esibelethweni sikamama, izingane zikhula amadevu nezinwele emzimbeni, ezidlayo
Ingane ngayinye esibelethweni sikamama ikhula amadevu nezinwele emzimbeni, lapho kuqala ukuqala kokukhulelwa. Okokuqala, izinwele zivela ngenhla kwendlebe, kanti ngenyanga ezayo zikhula kuwo wonke umzimba. Lesi sici sibizwa ngokuthi iwegogo - futhi siyanyamalala amasonto ambalwa ngaphambi kokuba sibe khona. Izinwele ziphuma futhi zitholwa yisithelo, ngaphandle kokuhlala emathunjini.
4. I-fetus ivuselela umzimba womama ngesikhathi sokukhulelwa
Uma ngesikhathi sokubeletha kwengane umama athola noma yikuphi ukulimala, le fetus yenza ukugxila kwamaseli ase-stem ukuyibuyisela. Ukukhubazeka okuncane kwamalungu angaphakathi nakho kulungiswa ingane ngaphandle kokungenelela odokotela nemithi. Isibonelo, uma umama eqala ukwehluleka kwenhliziyo ngesikhathi sokukhulelwa, lo wesifazane uphinde abuyele ngokushesha.
5. Kuze kube ngo-1905, izinsana zaqhutshwa ngaphandle kwe-anesthesia
Ngaphambili, izinsana kwakudingeka zibe namandla nakakhulu, ngoba akekho oye wacabanga ngokubanika i-anesthesia ngesikhathi sokuhlinzwa. Ekupheleni kwekhulu le-XIX-XX, odokotela babecabanga ukuthi izingane ezisanda kuzalwa azikho inkumbulo eyaziwayo, okuqeda isidingo sokusungula i-anesthetic. Isizathu salo mithetho eshaqisayo yokuqhuba imisebenzi kwakuyizifundo zezilwane: izikhanyiso zesayensi zazikholelwa ukuthi izingane azibonakali ubuhlungu, nje kuphela emzimbeni we-spinal.
6. Unesimiso sokuphefumula esihlukile
Izingane ezisanda kuzalwa zinekhono abantu abadala abangaphupha ngalo: angaphefumula futhi agwinye ngesikhathi esifanayo. Izingane zinezinyanga ezingu-9: eduze konyaka kuqala ukwakheka kwamapayipi okugcoba nokunciphisa i-larynx futhi leli khono lilahlekile. Ngaphezu kwalokho, izingane ziphefumula kabili njengabantu abadala. Abawazi nokuphefumula ngomlomo - ikhono litholakala kamuva, ngesikhathi sokucinana kokuqala kwesisu.
7. Izenzo ezisanda kuzalwa kumama njengomuthi
Ingane ayilimazi empilweni yomama futhi ayibangeli ukuthembela kwakhe, kodwa nakanjani ikhulula izinzwa zayo ezimnandi. Ukuxhumana okuqondile nengane yakho kwenza ukuba kuqhume ukuxilongwa kwe-oxytocin emzimbeni wakhe - i-hormone ejabulisayo, i-muscle ephumuzayo futhi inciphise ubuhlungu obukhulu.
8. iminwe yengane ayishiyi noma yimaphi ama-prints
Ngomunye umuntu omdala omunwe ngomunwe uqobo: umelela umzila we-fat. Futhi ezinganeni, umsebenzi we-secretory wehlisiwe, ngakho-ke akunakwenzeka ukususa iminwe egcwele yeminwe. Ngesizathu esifanayo, izingane ezincane emanzini ngokushesha zikhuni isikhumba.
9. Ingane engasanda kuzalwa ingaphakanyiswa emoyeni ngombono wokubamba
Uye wahlakulela ukusizwa kwemvelo, okuyivumela ukuba aphendule ngokushesha ekuthinteni. Ingane iyabamba yonke into ewela entendeni yakhe futhi iyilungise. Ososayensi bathi bangakhuphuka ngaphezu kwesikhalazo ngenxa yalesi sicabangela, kodwa ungasikhuthazi ukuphinda uyiphindise ekhaya: izingane zingakwazi ukukhululeka ngokuzumayo.
10. Izingane ziqala ukufunda ulimi nokukhuluma komama ngisho nangaphambi kokuzalwa kwabo
Ukufakazela ukuthi ukukhala kwezingane akunawo ubuzwe nokugcizelela okuphikisana nakho. Ngesikhathi esesesibelethweni, usana lusebenzisa isigqi kanye nesimo somlomo wolimi olusuka kumama, futhi uma sizalwa, siyikopishe ngendlela yaso. Esikhathini sesayensi, lo mkhuba ubizwa ngokuthi "ingoma yokukhala" kuphela.
