How are fingernails made and where do they start?

Asked by xxporkxsodaxx (1386points) July 12th, 2008

My uncle was drunk a few nights ago and was telling a story about how he was trying to be like Evel Knievel…blah blah blah… and he ended up getting the tip of his finger stuck in the chain of his motorbike and then it broke at a right angle. He said his nail was ripped out, and it did, but when he was giving me his “grade A anatomy” of where the fingernail starts, he kept pointing at the middle section of the finger. I have my doubts, but I’ll ask the collective.

I believe it’s only a few millimeters past where you can see the nail.

fingernails, like your hair, are composed of a protein called keratin. Have you ever wondered what the white half-moon like base does. Well that’s the lulnula, which manufacters keratin for your nail. The new keratin produced by the lulnula pushes your nail outward, thus making it grow.
