Action. The first phalanx is moved towards the palm by this muscle, 

 and the metacarpo-phalangeal joint is bent. 



The ADDUCTOR vel OPPONENS MINIMI DIGITI, G, resembles the opponens 

 pollicis in being attached to the metacarpal bone. Its origin is from the 

 process of the unciform bone, and the lower part of the annular ligament; 

 its insertion is fixed into the ulnar side of the metacarpal bone of the little 

 finger.

Action. It raises the inner metacarpal bone, and moves it towards the 

 others, so as to deepen the palm of the hand.
