I-Medical Science Fetal Ukukhulelwa Ukukhulelwa Imodeli Yentuthuko Yentuthuko Embri 10-Piece Set Laborator Hostel Model

Amamodeli ayi-10 asethelwe ukukhombisa ubudlelwano phakathi kwenqubo yokuthuthuka ye-fetus kanye nesibeletho ekukhulelweni ngo-Okthoba. Iqanda libizwa ngokuthi likhulelwe noma livundiswe kungakapheli amasonto ama-2 ngemuva kokukhulelwa; Amasonto ama-3-8 emva kokukhulelwa abizwa ngokuthi imibungu; Kusukela ekugcineni kwesonto le-8, ibizwa ngokuthi ingane; Amaviki awu-8; Umbungu ucishe ube yi-3cm eside futhi useqalile ukuthatha isimo somuntu, enekhanda elikhulu ikakhulukazi, amehlo abonakalayo, izindlebe, ikhala nomlomo. Ukwakheka kwenhliziyo kusenesikhathi nokugqekeza kungatholwa ukuhlolwa kwe-ultrasound. Emavikini ayi-12, ingane ingu-7 ~ 9cm ubude futhi inesisindo esingu-20G. I-Orthogonia ye-Orthogonia yenzeke, kukhona umsebenzi obuthakathaka ezilingweni, futhi izikhungo ze-ossification zivele emathanjeni amaningi. Emavikini ayi-16, ingane ingaba ngu-10 kuye ku-17cm ubude futhi inesisindo esingu-100 kuye ku-120g. Inesikhumba esibomvu, esibushelelezi futhi esibonakalayo ngenani elincane lezinwele ze-vellus. Ukuthuthuka kwamathambo okwengeziwe, ukuhlolwa kwe-x-ray kungabona isithunzi samathambo, i-stycttecher yangaphandle ingahlukanisa owesilisa nowesifazane. Ukuhlolwa kwesisu kungazwa inhliziyo ye-fetal kuzwakalayo, abesifazane abakhulelwe bangazizwa ukunyakaza kwe-fetal. Emavikini angama-20, i-fetus ingu-18 ~ 27cm ubude, inesisindo esingu-280 ~ 300g, isikhumba sinciphile, i-fasturency iphonswa amafutha e-fetal, i-Fetal head account for 1/3 yomzimba , futhi umsebenzi wokugwinya uyaqala. Amaviki angama-24 ubude bomzimba we-Fetal ubude 28 ~ 34cm, isisindo 600 ~ 700g, amanoni aphansi aqala ukufaka imali, imibimbi yesikhumba. Emavikini angama-28, ingane ingu-35 ~ 38cm ubude futhi inesisindo esingu-100 ~ 1200g. Umzimba wonke umncane, isikhumba sibomvu, kukhona amanoni we-fetus omunwe (uzwane) nail awafinyeleli umunwe (uzwane). Kwabesifazane, i-Labia Majorsa iqukethe i-Labia Minora kanye ne-clitoris, kwabesilisa, amasende awehlela eScrotum. Ngenxa yamafutha amancane aphansi, imibimbi ebusweni, njengendoda endala. Uma ezalwa, zingakhala, zigwinye, zihambisa izinyawo zazo, kepha zibuthakathaka futhi zidinga ukunakekelwa okukhethekile ukuze zisinde. I-32-DEVE FEtus ingu-40cm ubude, inesisindo esingu-1500 ~ 1700g, isikhumba sibomvu esimnyama, izinwele zobuso ziwile, futhi zingasinda ngemuva kokunakekelwa okufanele. Emavikini angama-36, ingane ingu-45 ~ 46cm ubude futhi inesisindo esingama-2500g. Amafutha aphansi, imibimbi yobuso inyamalale, umunwe (uzwane) isipikili selifinyelele umunwe (i-toe tip). Ngemuva kokuzalwa, ukukhala nokuncelisa kunethuba elihle lokusinda. Ingane ivuthiwe emavikini angama-40, ngobude obungama-50cm kanye nesisindo esingaba ngu-3000 ~ 3300g. Isikhumba sipinki, amafutha aphansi athuthukiswa kahle, iningi le-fetus selidlulile, futhi izinwele zingu-2 ~ 3cm ubude. Izipikili zomunwe zidlulile phezu kwesihloko somunwe. Ukunyakaza kwe-limb esebenzayo, i-loutring comloning, i-reflex enamandla. Ubude bomzimba kanye nesisindo Khuphuka kancane kancane ngenyanga yokukhulelwa, ukuze kube lula inkumbulo, ifomula elilandelayo ngokuvamile lisetshenziselwa ukubala: ngaphambi kokubala amasonto angama-20 ubude be-Gensi (cm), ngemuva kwamasonto angama-20 Ubude bokukhulelwa = Inani lokukhulelwa izinyanga × 5 (cm).
