A finger is a type of digit attached to the hand. If you touch something you will feel what it's like. Our type of fingers are similar to those of other primates. They are used for doing things and feeling things.
Humans have five digits, the bones of which are termed phalanges. The first digit is the thumb, followed by the index finger, middle finger, ring finger, and little finger or 'pinky'. According to different definitions, the thumb can be called a finger, or not.
