digitof a human handis 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
thumband the middle finger. It is usually the most dextrous and sensitive fingerof the hand, though not the longest. A lone index finger often is used to represent the number1, 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 (often saying "We're number one!") while posing for a championship team photo.
Studies have also found that a smaller index finger compared with the
ring fingerindicates a better athlete. [ [http://www.news.com.au/story/0,23599,20490243-13762,00.html News.com.au report] ] 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 osteoarthritis, especially for women with such ratios.

As mentioned above, the forefinger can be used for pointing. However, this
gestureis considered rude in some countries ( Ukraine, Russiaand Chilefor instance), in the former two pointing with the whole hand is considered polite.
Bosnian war, Serbo-Bosnian troops raised three fingers in a sign of victory, Bosnian Croats raised the two-finger V-signand Muslims ( Bosniaks) raised one (after the strict monotheism of Islam).
