• The skin on your fingertips is more sensitive
  than on other areas on your hand. You can feel
  things and tell what they are more easily with
  the tips of your fingers than you can with the
  palm or the back of your hand. The ridges in
  your fingertips make it easier for you to hold on
  to things. These ridges also make your
  fingerprints.
