Question

Which of the following graphs indicate what you would expect to see when a fracture has occurred within a bone?

A: http://prntscr.com/9a98on
B: http://prntscr.com/9a98sl
C: http://prntscr.com/9a98wo
D: http://prntscr.com/9a9902

I think it might be A or C, but I'm not sure...

Answer 1

okay well its def not D

Answer 2

I think it might be A, just because osteoblast activity would increase if a bone was fractured right?

Answer 3

Osteoblasts are described as the bone-forming cells, so they would increase if it was fractured. I get that much, but the fact of how far away from the injury site it is confuses me on the graphs.

Answer 4

Well since they are bone forming cells, wouldn't you think they would be very close to the injury site because they would be forming new bone to replace the fractured part

Answer 5

I think A is basically saying that osteoblast production will be low when it is near the fracture, but the production will increase when it's farther away from the fracture.

Answer 6

That what I think too, so i'd go with A.

Answer 7

A

Answer 8

but you just said you think the production would be high near the fracture... A is saying the opposite.

Answer 9

A says it's LOW when it's NEAR the fracture but HIGH when it's FARTHER AWAY from the fracture.

Answer 10

I think it would depend on the size of the fracture, if the fracture was big, osteoblast production would be higher and more spread out among the bone, but if it was small, osteoblast production would be lower and more compact near the fracture.

Answer 11

But the size of the fracture doesn't seem to come into the graphs at all.

Answer 12

I know that's where im confused.

Answer 13

see, B says that production would be high near the site of the fracture but low farther away from it.

Answer 14

you know what, I think im just now understanding the question lol, I totally get what you were trying to say, I was making no sense. its most likely B

Answer 15

and you're sure C isn't it? it basically says osteoblast production stays the same no matter how far away it is.
I know the production would increase when the injury happens, but do we really know if distance has anything to do with it?

Answer 16

no distance doesn't have anything to do with it, the osteoblasts would be more at work when there is a fracture as they would be when there isn't an injury at all, So i'd go with B

Answer 17

okay, are we SURE this time?

Answer 18

Yes haha.

Answer 19

Okay, thanks!

Answer 20

No problem
