Digit (anatomy)
Digit (/ˈdɪdʒɪt/; from Latin digitus, "finger, toe") is a term used in anatomy to refer to certain body parts that extend from the main structure of the body. In humans, a digit is one of the terminal members of the hands and feet, such as a finger or toe.
Etymology
The term "digit" comes from the Latin word digitus, which can be translated as "finger" or "toe". The use of the term in English to refer to fingers and toes dates back to the 14th century.
Anatomy of a Digit
A digit in humans consists of several parts, including the phalanges (bones), joints, nails, and the surrounding soft tissues and skin. Each digit, except the thumb and the big toe, has three phalanges: a proximal, a middle, and a distal phalanx. The thumb and the big toe have only two phalanges.
