Fingers of the human left hand

A finger is a type of digit, an organ of manipulation and sensation found in the hands of humans and other primates.Normally humans have five digits on each hand (exceptions are polydactyly, hypodactyly and digit loss). The first digit is the thumb, followed by index finger, middle finger, ring finger, and little finger or pinky. Some other languages use the same generic term for all five digits of a hand.

Linguistically, it appears that the original sense was to include the thumb as a finger: penkwe-ros (also rendered as penqrós) was, in the inferred Proto-Indo-European language, a suffixed form of penkwe (or penqe), "five", which has given rise to many Indo-European languages-family words (tens of them defined in English dictionaries) that involve or flow from concepts of fiveness.

Chimpanzees have lower limbs that are specialized for manipulation, and (arguably) have fingers on their lower limbs as well. The term 'finger' is not applied to the digits of most other animals, such as Canidaes, felines, or ungulates, none of which can engage in fine manipulation with their forelimbs as a human can.

Function Each finger may Flexion and extend, abduction (kinesiology) and adduction; therefore it may also circumduct. Flexion is by far the strongest movement. In humans, there are two large muscles that produce flexion of each finger, and additional muscles that augment the movement. Each finger may move independently of the others, though the muscle bulks that move each finger may be partly blended, and the tendons may be attached to each other by a net of fibrous tissue, preventing completely free movement. This is particularly noticeable when trying to extend the fourth digit (third finger) with the others flexed.

Fingers are usually moved under conscious control. In humans, they are used for grasping, type, grooming, write, Physical intimacy, and many other activities. They are also used in signaling, as when wearing a wedding ring, finger counting or when communicating in sign language.

Aside from the sex organ, the fingertips possess the highest concentration of somatosensory system and thermoreceptors among all areas of the human skin, making them extremely sensitive to heat (and cold), pressure, vibration, texture, and moisture. Fingers are thus commonly used as sensory probes to ascertain properties of objects encountered in the world, and in such a role, they are prone to injury.

Fingers do not contain muscles other than arrector pili muscles. The muscles that move the finger joints are in the palm and forearm. The long tendons that deliver motion from the forearm muscles may be observed to move underneath the skin at the wrist and on the back of the hand.

Fingers Each of the fingers has unique cultural and functional significance. From the thumb on the radius (bone) side to the ulnar side of the hand, the fingers are in this order:

thumb

index finger, also called 'pointer finger', 'first finger', or 'forefinger'

middle finger, the longest

ring finger, also known as fourth finger

little finger, also known as 'pinky'

Disease A rare anatomical variation affects 1 in 500 humans, in which the individual has more than the usual number of digits; this is known as polydactyly. A human may also be born without one or more fingers, leading to a reduced total number.

Phalanx bones are commonly Bone fractured. A damaged tendon can cause significant loss of function in fine motor control, such as with a mallet finger.

The fingers are commonly affected by diseases such as rheumatoid arthritis and gout. Diabetics often use the fingers to obtain blood samples for regular blood sugar testing. Raynaud's phenomenon is a neurovascular disorder that affects the fingers.
