Těhotenství: 12. týden

18. únor 2012

Víte, že se pomalu dostáváte do finální fáze prvního trimestru? Co to pro vás a miminko znamená? Kam už se posunul vývoj plodu?


Těhotenství: 12. týdenTěhotenství: 12. týden

Vaše těhotenství se právě nachází v předposledním týdnu prvního trimestru. Překlenula jste nejdůležitější a nejcitlivější údobí. Stav plný změn a zvykání si na novou situaci, na „jiný stav“. Obzvláště embryo a později už plod zaznamenal velmi dynamický vývoj a pokrok.

Miminko se čímdál více začíná podobat člověku. Za tři měsíce dospělo až do fáze, kdy si vytvořilo několik složitějších reflexů, jako je sevření rukou v pěst a dokonce umí i sát. Je také tvůrcem mnohých grimas, umí se mračit, ale i natáhnout, polykat. Dokáže reagovat na mechanický podnět z venku, a to pohybem. Až tak aktivní je vaše děťátko.

V tuto chvíli je velké přibližně 5,5-6 centimetrů a váží asi 10-13 gramů. Ačkoliv se pohlavní orgány stále intenzivně vyvíjejí a například chlapcům rychleji roste pohlavní hrbolek (pozdější penis), přesto je nesnadné ještě určit pohlaví.

A jakých dalších pokroků miminko dosáhlo?

  • překotně se rozvíjí nervový systém
  • oči se přibližují k sobě
  • ušní lalůčky se posouvají na správné místo
  • nos a brada se zmenšily
  • nohy a ruce se čile pohybují (dolní končetiny ale zaostávají v růstu; objevují se malé nehtíky; celkově jsou končetiny hubené)
  • střeva předtím rychle rostla a byla tak mimo břišní dutinu, nyní se vrací zpět do břicha
  • ledviny už vylučují moč do močového měchýře
  • žaludek je již vytvořen (je spojen se střevem a ústy)
  • formuje se tvar kostí a kloubů (ale přeměna chrupavčitého základu na kost proběhne až déle)

A jaké změny pociťuje maminka?

Na ženě je konečně její „jiný stav“ viditelný. Maminka sice ještě neprodělala výrazný váhový přírůstek, ale její postava se začíná měnit. Děloha se dosud zvětšila natolik, že se její koncová část nachází až nad stydkou sponou. Většího objemu nabyla i prsa.

V tuto chvíli může maminka také objevit pigmentové skvrny, a to hlavně na obličeji a krku a dost možná i zaznamená pigmentovou čáru od pupku až dolů k ochlupení. Veškeré skvrnky ale po porodu dřív či později vymizí.

Žena se již prakticky nachází na přelomu dvou trimestrů. To s sebou přináší obvykle zmírnění či vymizení nevolností a dalších nepříjemných příznaků. Naopak se může maminka cítit plná energie, bude spíše aktivnější a nepociťuje v takové míře únavu.

A která vyšetření žena podstoupí?

Opět na maminku čeká vyšetření krevního tlaku, moči a váhového přírůstku. Kolem 11. a 12. týdne zpravidla probíhá screening genetických vad plodu (jedná se o vyšetření pomocí krevních odběrů a ultrazvuku).

Hey I know this is off topic but I was wondering if you knew of any widgets I could add to my blog that automatically tweet
my newest twitter updates. I've been looking for
a plug-in like this for quite some time and was hoping maybe you would have some experience with something like this.
Please let me know if you run into anything.
I truly enjoy reading your blog and I look forward to
your new updates.

I've been surfing online more than three hours today, yet I never
found any interesting article like yours. It is pretty worth enough for me.
In my opinion, if all web owners and bloggers made good content as you did,
the web will be much more useful than ever before.

Hi there just wanted to give you a quick heads up. The text in your
article seem to be running off the screen in Ie.
I'm not sure if this is a format issue or something to do with web browser compatibility but I figured I'd post to let
you know. The design and style look great though!
Hope you get the problem resolved soon. Kudos

I believe everything typed made a ton of sense.
However, consider this, what if you added a little content?

I mean, I don't want to tell you how to run your blog, however what
if you added something to maybe grab a person's attention? I mean T hotenstv : 12.
tden is a little plain. You might look at Yahoo's front page and note how they
create article titles to get viewers to open the links. You might add a video or a related picture or two to get readers interested about what you've got to say.
Just my opinion, it would make your website a little bit more interesting.

I mean, what you say is important and all. But just
imagine if you added some great images or video clips
to give your posts more, "pop"! Your content is excellent but with images and video clips, this website could undeniably be one of the best in its

First off I want to say superb blog! I had a quick question which I'd like to
ask if you don't mind. I was curious to find out how you center yourself and clear your mind before writing.

I've had trouble clearing my mind in getting my ideas out there.
I do take pleasure in writing however it just seems like the first 10 to 15 minutes are generally wasted simply just trying
to figure out how to begin. Any recommendations or
hints? Thanks!

Anyway, should you have any recommendations or tips for new blog owners please

Appreciate it!

Létání v těhotenství: pohoda, nebo risk?

Je čas dovolených a mnozí z nás tak vyrážejí do různých koutů světa a různými dopravními prostředky. Na dovolenou odjíždí samozřejmě i těhotné ženy. Jakou dopravu by právě ony měly zvolit, aby jejich dovolená proběhla bez komplikací?

Cestování versus těhotenství

Cestování versus těhotenství

Těhotenství není nemoc a proto i cestování není v tomto „požehnaném stavu“ zakázáno. Ale jako se vším i zde platí možná rizika. Zvláště pak při cestování na delší vzdálenosti.

Strie v těhotenství: jak s nimi bojovat?

Strie jsou takzvané pajizévky (vnitřní jizvy), kdy povrch kůže zůstává neporušený, ale naopak v kůži pod striemi téměř chybí elastické vlákno a pokožka pod povrchem tak popraská. Vznik pajizévek postihuje v těhotenství až 90% žen.

Špinění v těhotenství: co může značit?
