In an effort to procrastinate doing everything...okay, really simply to revise my material for next semester when I start working at hospitals (but the first one sounds less dorky D
...anyway...
In an effort to revise my material, I'm inviting each and every one of you to ask any questions you had on the human body (and mind). As long as it's medical, it can be pretty much anything- and I'll attempt to answer it as quickly as possible, hopefully off the top of my head.
I can tell you what a mole is...It's an animal that has very porr eyesight and relies on hearing. They spend all day burrowing tunnels under the ground. And they're pretty stupid..
Wow, the thread got revived! This might be a bit late...but let's see.

i 8 a chicken bone n i swallowed it 5 mins ago!! wat should i do?? is this serious? btw the bone was about 5 cm long....
That might depend on how long and how sharp the bone was. If you're still haven't been admitted to the hospital with a nasty bout of peritonitis by now, I'd say you're okay :P
Bones can be digested too- they may just take a longer time to dissolve.
How can you tell if moles are cancerous? Also what exactly is a mole?
A mole (also known as a naevus) is a patch of 'hyperpigmented' skin. It usually comes about as a response to sunlight hitting the skin- in the lower layers of the skin, special pigment producing cells called melanocytes will produce melanin which effectively darkenes the skin. This helps the skin absorb harmful UV rays and therefore protects the skin cells from damage which may trigger a cancerous growth.
Moles usually are harmless and look like flat, small round brown (or black) spots. Nearly everybody (with the exception of very dark and albino people, I think) will pick up a few if they spend any amount of time in the sun (which, unless you are allergic to light, as some people are, is important for the biosynthesis of vitamin-D!)
What are the warning signs that a mole might be not-so-good? If several of the below are true:
* It's larger than 5mm across (a single one- sometimes moles can end up being really large due to them clustering together and this is okay). * It's raised or bumpy. * It's irregular in shape (not largely circular or ovoid) * It's bleeding * It's not a usual skin color * It's got hair growing from it * It has changed shape or size (grown) noticeably.
If, say, three or more of the above are true, you should probably get it checked out immediately by a doctor.
There are other types of skin cancers that aren't related to moles, though. I won't go through them for the time being, though, as it's not directly relevant to the question.
When I work really hard, my hands grow for a day. Then, they shrink. Why does this happen?
When you say work really hard, I'm going to assume that you do a lot of manual labor.
If that's the case, then most likely your hands are swelling from fluid buildup in your extremities. What probably happens is that working hard causes increased bloodflow to your hands. The blood vessels aren't exactly watertight, so a bit of fluid leaks out into the surrounding tissues (and eventually gets taken back in the lymph vessels)- and increasing the pressure and flow through certain areas increases the leakage. This causes a buildup of fluid in your tissues which will make your hands look like they 'grow'. When the pressure returns to normal, leakage reduces and the swelling is cleared away, so the hands will shrink to their usual size.
what causes ADHD and why does that make so That I can't even look at a hot chick without getting distracted
I actually can't answer this question because nobody knows. In fact, there's a huge amount of controversy around such things as ADD/ADHD from diagnosis to treatment and implications, so much of it is fairly uncertain.
What we do know is that ADHD is classified as a 'behavioral disorder'. The clinical guidelines for ADHD are such that there is no single diagnostic test for it, and thus diagnosis is somewhat 'discretionary'. What this also tells us is that there's no single known cause...at best we may be able to identify a number of associated factors but these are nowhere near strong enough to be called a 'cause'.
The same applies to many other developmental and behavioral disorders such as autism (another can of worms, that!)
@BASHA - I can't look at a hot chick without being distracted...and I aint got ADHD or ADD!
Anyways.....
Is is possible to get shocked so badly by static electricity that a bump can form on your arm? This happened to me...and I had a bump for at least a week afterwards...?
Strop, you are good at these questions and I got some for you. 1.) Once you have a heart attack, is there any side affects that can lead to another heart attack.
2.) What will happen if you had cancer in your brain and then could you die faster if you had a brain tumour.
