Amasonto angu-12 wokukhulelwa kubaluleke kakhulu ekuthuthukiseni umntwana: i-trimester yokuqala iphela, i-placenta isakhiwe ngokuqinile, ingozi enkulu yokudala isisu esinzima nokukhipha isisu sekuvele sekuvele. Sifunda ukuthi isithelo singaziqhayisa kanjani emasontweni angu-12 nokuthi ukuthuthukiswa kwayo kwenzeka kanjani ngalolu suku.
Anatomy of the fetus amasonto angu-12
Emasontweni angu-12, umbungu womuntu, noma kunalokho umntwana, ekugcineni usuqalile futhi ufana nendoda encane encane. Zonke izitho zisezindaweni zazo, kodwa iningi lazo lingakasebenzi, kuphela okubaluleke kakhulu futhi okubaluleke kakhulu okusebenzayo. Ngakho-ke, inhliziyo yenhliziyo emine ikhala ngesilinganiso sezinsimbi ezingaba ngu-150 ngomzuzu, isibindi siqala ukukhiqiza i-bile esidingekayo ekugayeni amafutha, isisu senza ukusikeka komzimba, nezinso zikhiqize umchamo.
Ubuchopho be-fetal bamaviki angu-12 bufana nobuchopho obuncane bomuntu omdala: yonke iminyango yayo yakhiwa, futhi ama-hemispheres amakhulu ahlanganiswe ne-convolutions. Umzimba we-pituitary, osezingeni elingezansi lobuchopho, uqala ukukhiqiza ama-hormone.
Ingane isalokhu ingavumelani: ikhanda likhulu kakhulu kune-trunk. Emasontweni angu-11 kuya ku-12 umntwana usengumzimba omncane kakhulu futhi akabukeka njengomntwana osanda kuzalwa. Isikhathi sokugcina amafutha siyofika kamuva, futhi manje imisipha iyakha futhi ikhula, ukwakheka kwamathanga amathambo kuqala, emashumini avela amazinyo amazinyo ahlala njalo, naseminwe yezandla nezinzipho ezincane. Manje udinga i-calcium namaprotheni kunanini ngaphambili, ngakho-ke umama ozayo kufanele acebise ukudla kwakhe nemikhiqizo equkethe lezi zinto.
Ekupheleni kweviki le-12 ukwakhiwa kwesimiso sokuzala kwengane kuphelile. Manje ngosizo lwe-ultrasound ungabona ukuthi umfana uzalwa noma intombazane. Egazini lomntwana, ngaphezu kwamangqamuzana egazi abomvu (amangqamuzana egazi abomvu), kukhona amangqamuzana amhlophe egazi (amangqamuzana egazi amhlophe), okusho ukuthi ukuzivikela komzimba kuvela. Yiqiniso, ngaphambi kokubeletha nezinyanga ezimbalwa emva kwalo, izidumbu zomzimba zomama zizovikela iziqu.
Ukuthuthukiswa kwe-Fetal amasonto angu-12
Ekupheleni kwe-trimester yokuqala ingane isisindo esingaba ngu-14 g, futhi ukukhula kwayo kusuka emqhele kuya komsila kuyinto engu-6-7 cm. Ubuchopho bukhula ngokushesha, izinhlelo zezinzwa nezisiphako zikhula. Ingane ingakwazi ukugcoba, ivule futhi ivimbe umlomo wayo, igqoke, igwebe iminwe yakhe nezinzwane, icindezele futhi ingene izibhamu zayo kanye nesifo somzimba esibelethweni. Kumama ozayo, izivivinyo ze-acrobatic zisalokhu zishayekile: ukuguqulwa kwe-fetus emasontweni angu-12 kusabuthaka futhi kungabonakali. Kukhona ezinye izizindla ezingenakunqunywa: ngokuthinta isibeletho, isithelo sisuka kuso, siphuza umunwe noma isibindi, siphenduka ekukhanyeni okukhanyayo.
Ngalesi sikhathi ingane ingakwazi ukuhlukanisa ukunambitheka, ukugwinya amniotic fluid. Uma umama adla into enomuncu noma emuncu, omncane ubonisa indlela okumnandi ngayo ukunambitheka kuye: ukuphikisa ubuso bakhe, ukubeka ulimi, ukuzama ukugwinya njengokuncane okusemandleni amniotic fluid.
Ngaphezu kwalokho, ingane iqala ukwenza ukunyakaza kokuphefumula. Yiqiniso, lawa ayikaphefumli ngokugcwele nokuphefumula: igumbi lomlomo livaliwe futhi amniotic fluid ayifaki emaphashini. Kodwa-ke, isifuba somntwana njalo sihluma futhi siwa - lokhu kuqeqeshwa kwemisipha yokuphefumula kuyohlala kuze kube sekupheleni kokukhulelwa.
Yini ongayibona ku-ultrasound emavikini angu-12?
Njengoba kuyaziwa, kusukela ngesonto le-12 bonke abesifazane abasesimweni banikezwa ukuhlolwa kokuqala kwe-ultrasound ekukhulelwe . Lokhu akukwenziwe ukuze kunqume ubulili bomntwana (izibonakaliso zangaphandle zobulili namanje azibonakali kakhulu). Umsebenzi oyinhloko wokutadisha ukukhipha ukukhubazeka okukhulu okuthuthukisayo kanye ne-pathologies yomntwana.
Ukuqaphela ikakhulu kunikezwa:
- ubukhulu be-fetus emavikini angu-12 (ngokuvamile ingane isisindo esingu-14-19 g, ubude bayo buyi-7-8 cm, ubukhulu bekhanda buyi-21 mm, nobubanzi besifuba buyi-24 mm);
- ukuqina kwesikhala sekholomu (akufanele kudlule u-3 mm, kungenjalo ingozi ye-chromosomal engavamile kungenzeka);
- ukuthuthukiswa kwe-placenta (kubalulekile ukukhipha ukuguga ngaphambi kwesikhathi ngaphambi kwe-placenta nezinye izifo);
- indawo ye-fetus ngeviki 12 (kungenzeka kube nendawo ephansi yokubeka indawo, kodwa, njengombuso, ngesikhathi, i-placenta "ihamba" iphinde ifike ngaphansi kwesisu).
