April MCATers, let's practice together

[Premed315U]

Everyone, let's post some questions for each other from our practice materials/tests. It will probably individually help us even as we post the questions by reinforcing the answers. Let's make a big database of practice questions here to teach each other.

Here's question #1
Menstruation is prevented by increased levels of which of the following?
a) oxytocin
b) luteinizing hormone
c) estrogen
d) progesterone

I think it's LH. An estrogen spike induces menstruation.

 

[Premed315U]

No, progesterone.

Anyone have other questions to add?

 

[Mystique]

Correct me if I'm wrong...but if I remember correctly, increased levels of progesterone and estrogen prevent menstruation.....so isn't the answer C and D???


(P.S. I'm not taking the MCAT so excuse me if I'm wrong)

 

[Premed315U]

No, it's just progesterone. )

hiya kids, so this is how i think it works..

Estrogen pikes induce ovulation, which in turn induce menstruation. if estrogen was inreased, the follicles would be stimulated to ovulate and finally menstruation would occur.

Prog. on the other hand, makes your body think that you have just ovulated, and your egg was not fertilized...basically, you are constantly in post leutal phase. this prevents the egg from even reforming in your body. Atleast, this is what i *think* happens.

can we try and keep this group cohesive with the other group--April MCATers Club? it's kinda hard to keep going back and forth b/w both the threads, among the million others on the page.

I personally like the idea of just having ONE thread, all concerns/practise q's/etc etc etc in there. That way, with our busy lives all we have to do is click on that ONE thread and see it all. Whaddy'all say? Until then, I am going to try and keep the two groups together by bumping each one at the same time.

Tweetie, sorry for starting the new one. I was hoping to grab attention to the question idea by having a separate topic. But I like your idea much better )

Here's a little personal experience that may help. I am a small person, therefore my body produces less estrogen than someone with a larger body. I switched to birth control pills that were higher in estrogen because that reduces pimple breakouts. Well, after a few months, it made my period last incredibly long, we're talking 10-14 days...Turns out, it was too much estrogen for my body so I had to switch to a lower dose BC pill, one with higher progesterone, and therefore, put up with acne. sigh.

I hope that helps you remember it better. Even if it was too much info...

LOL, that's the cutest (right word?) example I have heard. Yes, that totally helps drive the point home!! lol, albeit it's kinda funny you'd volunteer yourself that way. it's just nice of you. I don't think anybody is going to miss that on the MCAT now... go KYDrGirl.
