Extensor digiti minimi functions primarily to extend the fifth digit at its metacarpophalangeal joint. It also contributes to extension of the wrist and all the fifth finger joints from the ulnar side of the hand, via it's attachment into the extensor expansion and by acting along with extensor carpi ulnaris muscle.
Beside this, what does the extensor digitorum do?
Extensor digitorum runs from the lateral epicondyle of humerus to the medial four phalanges of the hand. In this way, it generates the pull for the extension of the four medial fingers in their metacarpophalangeal and both interphalangeal joints. Extensor digitorum also participates in the extension of the wrist.

What two muscles is the extensor Digiti Minimi located between?
Description: The Extensor digiti minimi is a slender muscle placed on the medial side of the Extensor digitorum communis, with which it is generally connected. It arises from the common Extensor tendon by a thin tendinous slip, from the intermuscular septa between it and the adjacent muscles.
