A tshuaj teratogen yog tej yam khoom ib puag ncig lossis tus neeg sawv cev-biological, tshuaj, lossis lub cev-uas tuaj yeem muaj kev puas tsuaj nyhuv ntawm a tsim fetus . Kev nphav raug rau cov tshuaj teratogens thaum lub sij hawm cev xeeb tub theem tuaj yeem ua rau muaj kev pheej hmoo ntawm kev yug menyuam.
Ntxiv mus, vim li cas teratogens txaus ntshai rau tus poj niam cev xeeb tub?
Lub sijhawm no, cov tshuaj teratogens tuaj yeem ua rau neural tube tsis xws li spina bifida. Qee lub cev tseem ceeb rau cov tshuaj teratogens thaum tag nrho cev xeeb tub . Qhov no suav nrog tus menyuam lub hlwb thiab tus txha caj qaum. Cawv cuam tshuam rau lub hlwb thiab txha caj qaum, yog li nws tuaj yeem ua rau muaj kev phom sij thaum twg los tau cev xeeb tub.
Dab tsi theem ntawm cev xeeb tub yog teratogens teeb meem tshaj plaws?

Thaum lub sij hawm twg ntawm kev loj hlob ntawm cev xeeb tub ua rau lub cev thiab cov khoom nruab nrog cev pib ua haujlwm?
Thaum lub sij hawm embryonic theem, lub plawv pib ntaus thiab lub cev tsim thiab pib ua haujlwm. Lub neural tube tsim raws sab nraub qaum ntawm lub embryo, tsim rau hauv qaum qaum thiab lub hlwb
Dab tsi yog qee qhov kev hloov pauv ntawm lub cev uas tshwm sim hauv leej niam thaum cev xeeb tub?
Muaj ntau qhov kev hloov pauv tseem ceeb hauv cov txheej txheem nyuaj no thaum cev xeeb tub. 1 Lub siab. Lub plawv tuaj yeem nce qhov loj me thaum cev xeeb tub vim qhov nce hauv nws cov haujlwm. 2 Ntshav ntim. 3 Ntshav siab thaum cev xeeb tub. 4 Kev tawm dag zog thiab ntshav ntws thaum cev xeeb tub. 5 Edema thaum cev xeeb tub
Puas yog cev xeeb tub pib thaum cev xeeb tub lossis implantation?
Kev xeeb tub pib thaum implantation. Tib neeg lub neej yuav tsum pib nrog kev xeeb tub, tab sis kev xav tsis zoo ib yam li cev xeeb tub, qhov kawg ntawm qhov laj thawj, kev tshawb fawb, thiab cov pov thawj kho mob pom zoo pib thaum lub qe fertilized tiav cog rau hauv lub tsev menyuam thiab txhim kho mus rau hauv lub embryo noj qab nyob zoo
Puas yog ectopic cev xeeb tub yuav tshwm sim ntawm kev kuaj cev xeeb tub?
Puas yuav muaj Ectopic cev xeeb tub tshwm sim ntawm Kev Ntsuas Hauv Tsev? Txij li thaum cev xeeb tub ectopic tseem tsim cov tshuaj hCG, lawv yuav sau npe ua qhov kev kuaj mob hauv tsev zoo. Cov poj niam uas cev xeeb tub ectopic tseem yuav muaj cov tsos mob thaum cev xeeb tub xws li mob lub mis, xeev siab, pom, thiab lwm yam
Qhov txawv ntawm Singleton qhov chaw thiab cov chaw qhia parsimony yog vim li cas PI qhov chaw muaj txiaj ntsig zoo rau kev txiav txim siab Phylogentic kev sib raug zoo thaum S qhov chaw tsis yog?
Qhov txawv ntawm Singleton qhov chaw thiab Parsimony-Informative sites yog dab tsi? PI qhov chaw muaj txiaj ntsig zoo rau kev txiav txim siab phylogenetic kev sib raug zoo vim tias lawv muaj ob lub nucleotides sib txawv uas tuaj yeem tshwm sim ntau dua ob zaug thiab qhia tias tsob ntoo twg muaj ntau dua parsimonious
