Flexor digiti minimi (of hand)

The flexor digi minimi (or flexor digiti minimi muscle, latin: musculus flexor digiti minimi) is one of the muscles of the little finger or hypothenar muscles lying on the ulnar side of the palm.

The flexor digiti minimi is a thin muscle lying laterally to the opponens digiti minimi.


The flexor digiti minimi originates from the flexor retinaculum and the hamulus of the hamate bone.  


The flexor digiti minimi passes obliquely to the ulnar side and inserts onto the base of  phalanx of the fifth digit (little finger).


The main function of the flexor digiti minimi is to flex the little finger.


The flexor digiti minimi is innervated by the ulnar nerve.
