Most people have five fingers on each hand and five toes on each foot. Some people, however, are born with more or fewer digits on each hand or foot. Polydactyly is a condition where people are born with one or more extra toes or fingers, while ectrodactyly is a condition where people have fewer than five digits.
A finger can be divided into three main sections: the proximal, middle and distal phalanx. These are the sections of the finger between each joint.Learn more about Human Anatomy
