Digit (anatomy)
A digit (pronounced: /ˈdɪdʒɪt/) is a term used in Anatomy to refer to certain body parts that extend from the main structure of the body. In humans, digits are the fingers and toes.
Etymology
The term "digit" comes from the Latin word digitus, which means "finger or toe". It has been used in English since the 14th century to refer to the fingers and toes of humans.
Anatomy of a Digit
Each digit in humans is formed by several bones called phalanges, connected by joints. The number of phalanges in each digit varies: the human thumb and big toe have two phalanges, while the other digits have three.
The digits play a crucial role in various physical activities such as grasping, manipulating objects, and walking.
