I-anatomy of development fetal kwi-trimester yokuqala
I-trimester yokuqala yokukhulelwa iqala ukusuka kwiiyure zokuqala emva kokukhulelwa. Uphuhliso lomntwana lulo lulandelayo. Ngethuba lokuqala lokukhulelwa, iqanda elichumayo liya kwahlula, ekuqaleni ngeeseli ezi-2, emva koko emva kweentsuku ezine. Ukuba uthetha lula, i-morulu yinto yokuba ngumntwana ozayo. UMorula uzama ukufikelela kwisibeleko nakwi-tube fallopian phambili emva kokukhulelwa kwiveki yokuqala. Umntwana ozayo ufumana kwi-stocks yeqanda lomama zonke izinto ezibalulekileyo, kwaye yonke le xesha, njengoko kunjalo, ayixhunyiwe kwi-intanethi.
Ngomhla wesixhenxe umntwana ozayo uza kufakwa eludongeni lwesibeleko esiswini somama kwaye agqitywe khona. Iimbumba ezimbini zenza iiseli zangaphakathi zeqanda lomntwana. Emva kwexesha elinye lenza i-amniotic cavity kunye ne-amniotic fluid. Ngethuba elifanayo, i-placenta ezayo ivela kumntwana wesisu, apho uya kudla khona kwaye afumane amanqindi omzimba ukulwa nezifo kuzo zonke iiveki ezingama-39.
Kwixesha lokuqala lokukhulelwa, umama kuphela onokubiza umntwana omncinci umntwana. Oogqirha, de kube ngeveki ye-8, lo mqondiso omncinci uya kuba yintsholongwane (embryo). Kungenxa yokuba ebudeni beeveki ezingama-2-3 i-young man's look looks like a scribbler encinci kwaye ayigqithisi ubukhulu be-2, 5 mm.
Kwiiveki ezintandathu emva kokuchumisa, ikusasa lomntwana lenza izinto zokuqala zokugaya, inkqubo yengqondo kunye nenkqubo yesantya. Kukho iingcambu ezi-4 - amehlo esizayo kunye neendlebe zentsana, kwaye umsila, oza kuphuma ngokukhawuleza. Phakathi komzimba kunye nentloko ibunjwa intamo. Ubukhulu bexesha elizayo umntwana ukhumbuza "ubhontshisi".
Kwiiveki eziyi-8 ubuchule bomntwana bunzima. I-embryo ikhula ukuya kuma-8 mm, kukho izikhokelo zokuphatha, imilenze, intloko. Iyeza elisemthethweni, ukususela ngeli xesha, liyiqonda njengeziqhamo. Impembelelo yengqondo iqala ukulungiswa kakade kwi-crumb. Ekugqibeleni, amaqhina nemilenze yenziwe, ubuso buzuza izinto eziqhelekileyo: umlomo, impumlo, amaqoma. Ixesha elizayo umntwana uqala ukuhambisa ngokuthe ngqo ukuphatha kunye nemilenze.
Ngeveki 9, iintso ziqala ukusebenza, ngokususa ngokuthe kancinci iintsana ezingenasidingo ezivela egazini. Kumdlali onyanisekileyo umntwana ujika kwiiveki ezi-12-13. Uvula kwaye uvale umlomo wakhe, ugoba aze agule imilenze kunye neengalo zakhe, adibanise aze angenakunqanda. Ngeveki 15 umntwana ukhula ukuya kwi-10 mm. Intliziyo yakhe encinci ibetha ngokukhawuleza, kwaye zonke izitho eziphambili sele zenziwe. Kakade, ukuba kunokwenzeka, unokufumana isondo somntwana wakho kwi-ultrasound, yiva uze ubone iimvumba. Kungekho ixesha elingaphambi kokuzalwa komntwana.
Iingcebiso zokuphuhliswa kakuhle komntwana
Kwikota yokuqala yokukhulelwa emzimbeni womfazi, ezininzi ziqala ukutshintsha. Yaye ihamba kunye nje ngamaxesha amnandi. Abasetyhini abaninzi bayatshutshiswa yi-toxicosis benesimo sengqondo sokubuthathaka, isisonguluko. Ngokukodwa xa ukhulelwe. Kukho ukungcola kwiindawo ezininzi zokutya. Ufanele uphumule ngaphezulu, vuka, ungenzi ukuhamba ngokukhawuleza, ukwenzela ukuba ungabangeli ukuhlaselwa kwesicongconi. Ngeli xesha ixesha lesidlo sasekuseni embhedeni akusiyo i-luxury, kodwa kuyimfuneko. Ikhukhi kunye ne-bran, i-cracker encinane, indebe ye yogurt okanye i-yogurt, i-apula-yilokho okufunekayo kusasa. Umsebenzi womathumbu ngenxa yokutshintsha kwe-hormone eyenzekayo, iyancipha, edla ngokubakhokelela ekubanjweni. Zama ukwenza iimveliso zakho zokutya eziqulethe i-fiber enkulu yokutya, ngaphandle kokutya okutyiwayo. Efanelekileyo kwimifuno, iziqhamo, i-bran. Zama ukutya encinane kwaye rhoqo. Ukuhamba kuya kunceda ukuphucula inkqubo yokutya.
Kwimeko yokukhulelwa, ukuziphatha komama ozayo kuya kutshintsha. Oku kubonakaliswe kwinto yokuba iimoya ihlala ishintsha kwiindawo zo lonwaba olupheleleyo kwizinto zokungaxilwanga nokungalindelekanga. Zonke ezi tshintsho zidibaniswa neenguqu zeemichiza esele ziqala kwi-trimester yokukhulelwa. I-progesterone yehommone ikhiqizwa kulo lonke ukukhulelwa ngobuninzi kwaye isebenze kwinkqubo yeentlanzi njengexinzelelo. Umncinci omncinci ungakuthatha ngaphandle. Kufuneka uhambe ngokuphindaphindiweyo, vumela umzimba wakho uphumle. Kufuneka ukwazi ukuba umntwana sele uziva efana nawe. Udinga ukudala umoya wokuzola, ukuze kungabikho nkxwaleko ekukukubambayo kunye nosana lwakho lungazi. Umntwana wakho wesikhathi esizayo ukhula ngokukrazula kunye nemida, kwaye ngokoqobo ngeyure.
Ukwazi ngokuphuhliswa kwentombazana ekuthomeni kokuqala kokukhulelwa, abantu baya kuqikelela ukuba baphathe intombazane ukusuka kwiintsuku zokuqala zokuba khona.
