The opponens digiti minimi muscle ( Latin for "little finger counterpart") is one of the skeletal muscles of the ball of the little finger . Although it is called the counterpart of the little finger, it can hardly perform this task at all in humans. This muscle is not found in pets.
Both opposing muscles (opponens digiti minimi and opponens pollicis muscles ) work together to deepen the palm of the hand (scooping water) and are important for bringing the tip of the little finger into contact with the thumb.
