Where is my extensor digiti minimi?

Giving the finger...: It is a muscle located in the forearm and is responsible for movement of the little finger.

EDM to small finger: Extensor Digiti Minimi is a thin muscle of the forearm. It arises from the common Extensor tendon by a thin tendinous slip, from the intermuscular septa. Its tendon runs through a compartment of the dorsal carpal ligament then divides into two as it crosses the hand, and finally joins the expansion of the Extensor digitorum communis tendon on the dorsum of the first phalanx of the little finger
