The finger is any of the digits of the hand in humans and other species such as the great apes. The grace of the fingers is not sacrificed to their dexterity due to the placement of their muscles in the forearm, with motion communicated via long tendons which may be observed on the back of the hand. A notable exception is the thumb, with its flexor and rotators comprised in the hand itself.
The bones of the fingers are called phalanges (singular phalanx); the thumb has two phalanges, and the other fingers have three. The fingers have common names from the thumb inward:
Relative to much of the skin of the human body, the fingertips have a high concentration of nerve endings, equipping them as centers of tactilesensation; touching something or someone is often done with the hands and in particular the fingers.
Another important example of this capacity is in the ability to read Braille. Additionally, prehension is enhanced by the presence of the ridges and whorls known as fingerprints. Each finger is protected at its dorsal terminus by a fingernail (Latin unguis, unguiculus).
In young children, the fingertip is one of the few tissues in the human body capable of full regeneration, although this ability disappears after about age 6.
The finger program was written in 1971 by Les Earnest who created the program to solve the need of users who wanted information on other users of the network.
Finger information has been frequently used by crackers as a way to initiate a social engineering attack on a company's computer security system.
For these reasons, while finger was widely used during the early days of Internet, by the 1990s the vast majority of sites on the internet no longer offered the service.
