The middle finger, also known as the long finger or tall finger, is the third digit of the human hand, positioned between the index finger and the ring finger. It is usually the longest finger. In anatomy, it is also called the third finger, digitus medius, digitus tertius, or digitus III.
The middle finger has played a significant role in various cultures and historical periods. It is often used as a symbol of insult or defiance, particularly when extended in a specific gesture.
