In anatomy, it is also called the third finger, digitus medius, digitus tertius or digitus III.

In Western countries, extending the middle finger (either by itself, or along with the index finger in the United Kingdom: see V sign) is an offensive and obscene gesture, widely recognized as a form of insult, due to its resemblance of an erect penis.
