why is it so painful when you bang your knee bone into something, more painful than banging your elbow or hand

Answer 1

I would suspect it would have to do with the amount of nerves in your knee exceeding the amount found in your elbow or hand.

But, as this was submitted in the Astronomy & Space forums, who am I to say.

Answer 2

It's because your hand has waaaaaaaaaaaaaay more nerves than your knee, because you don't feel something with your knee do you?Natural selection made us this way so that we would know what we were touching and know if it was poisonous or harmful (like a snake).So therefore, when you hurt your hand, more nerves are sending the same signal to your brain.
Also, your knee has the hardest bones in your body.Even tougher than your skull.Why do we need tough knees?So when we bump it it doesn't hurt as much?Who knows?Who really knows?

Answer 3

Haven't discovered your funny bone yet, huh?
Your joints pain because they carry channels of bundled nerves, when you pinch one of these, you get a particular jolt.

Answer 4

Your leg is stronger and has more mass behind it so you tend to bang it a lot harder.

Answer 5

Try dropping something hard and heavy on your toes when they are cold.

Answer 6

And what does this have to do with Astronomy and Space...

Answer 7

more nerve endings?


in space?
