Editing Finger

'''Finger'''

A '''[[finger]]''' is one of the [[digit]]s of the [[hand]], and when compared to the [[toe]]s of the foot, it is a part of the body that is widely used in a variety of ways. It is an organ of manipulation and sensation found in the hands of humans and other primates.

== Anatomy ==

Each finger, except the thumb, has three [[phalanx bones]]: proximal, middle, and distal. The thumb only has two phalanx bones. The back of the finger is known as the dorsum.

=== Bones ===

The bones in the finger are the [[phalanges]] (singular: phalanx). The fingers are also referred to as digits, the same term that describes toes. The first digit is the thumb, followed by index finger, middle finger, ring finger, and little finger or pinky. According to different definitions, the thumb can be called a finger, or not.

=== Joints ===

The [[joints]] of the fingers include the [[metacarpophalangeal joint]] (MCP), the proximal interphalangeal joint (PIP), and the distal interphalangeal joint (DIP).

== Functions ==

Fingers have many functions. They are used for grasping, holding, and manipulating objects. They are also used for sensing.

== Diseases and conditions ==

There are many diseases and conditions that can affect the fingers, including [[arthritis]], [[Dupuytren's contracture]], and [[trigger finger]]. Injuries such as fractures and dislocations are common.
