The second digit of a human hand is also referred to as the index finger, pointer finger, forefinger, trigger finger, digitus secundus, or digitus II.
It is located between the first and third digits - that is, between the thumb and the middle finger. It is usually the most dextrous and sensitive finger of the hand, though not the longest. A lone index finger often is used to represent the number 1, or when held up or moved side to side (finger-wagging), it can be an admonitory gesture. With the hand held palm out and the thumb and middle fingers touching, it represents the letter d in the American Sign Language alphabet. In sports, it can also represent victory, as some championship-winning teams raise their index finger while posing for a championship team photo.
Studies have also found that a smaller index finger compared with the ring finger indicates a better athlete.[1] Men are 2.5 times more likely than women to have an index finger which is shorter than their ring finger, and such ratios correlate with an increased likelihood of osteoarthiritis, especially for women with such ratios.[2]

Gestures
As mentioned above, the forefinger can be used for pointing. However, this gesture is considered rude in some countries (Ukraine, for instance), and other gestures are used instead.
During the Bosnian war, Serbo-Bosnian troops raised three fingers in a sign of victory, Bosnian Croats raised the two-finger V-sign and Muslims (Bosniaks) raised one (after the strict monotheism of Islam).
