Opponens digiti minimi

The Opponens digiti minimi is a triangular muscle in the hand that is a part of how the fifth metacarpal, or the little finger, is able to move. It draws the metacarpal bone of the little finger to the front and rotates it in a lateral direction, which deepens the hollow of the palm, and brings the little finger into opposition with the thumb. It is located immediately below the flexor digiti minimi brevis. The Opponens digiti minimi is the largest of the hypothenar eminence or the three hypothenar muscles located on the outside of the palm of the hand that controls the little finger, the other two being the abductor digiti minimi and flexor digiti minimi. The origin of the Opponens digiti minimi muscle is in the lateral border of the flexor retinaculum of the wrist and in the hamulus of the hamate bone. Its insertion is in the whole length of the metacarpal bone of the little finger, along its ulnar margin.
