A、The amount of skin affected by the cut. B、The cause of the cut. C、The number of nerve endings irritated. D、The amount of bleed

M: Ow! That hurts!
W: What happened? Did you cut yourself’?
M: Yes—on the edge of this paper. How can such a little cut hurt so much? I’m not even bleeding, but my finger really hurts.
W: You know, I read something about that. It turns out that a little cut on a finger cart hurt a lot more than a big cut somewhere else.
M: Why? That doesn’t make any sense.
W: Actually, it does. There are more nerve endings in your hands than al most anywhere else in the body, and it’s the nerve endings that allow you to feel pain.
M: I guess that’s true.
W: Also, a little cut like yours won’t damage the nerve endings, just irritate them. If they were damaged, you would feel less pain, but the wound could be more serious.
M: So I suppose I should be happy my finger hurts so much?
W: Right. Now go get yourself a bandage.
M: Why? You just told me it’s not serious.
W: It’s not, but it does seem to be bothering you. Putting a bandage over the cut will keep the skin from drying and will help keep the skin together. If the skin stays together, the nerve endings won’t be exposed, and the cut will hurt less.
