Cheri Dotterer: That's absolutely true because the
nerves start in the brain and go all the way down in your arm.
They start at your fingertips and they go all the way up your

in this finger, you've got two in your thumb. You've got three
in this finger, you've got sensation, and very complex set
of bones in your palm and in your wrist.
