2i6 THE MUSCLES. 



largely of tendon-fibres, some of which pass directly from origin 

 to insertion. It may be regarded as a ligament. 



Origin, the lateral and ventral surface of the calcaneus near 

 the proximal end. It passes distad and slightly laterad outside 

 of the quadratus plants. 



Insertion, the lateral side of the base of the fifth metatarsal, 

 and the adjacent surfaces of the cuboid and calcaneus. 



Action. Probably causes slight motion of the cuboid on 

 the head of the calcaneus. 



M. scaphocuneif oratis. A small muscle lying on the sole 

 of the foot in the depression between the lateral cuneiform, 

 medial cuneiform, and the lateral tubercle of the scaphoid. It 

 is hidden by the overlying ligaments. 



Origin, the lateral tubercle of the scaphoid bone. It passes 

 distad and laterad. 



Insertion, the lateral surface of the medial cuneiform. 



Action. Rotates the medial cuneiform on the scaphoid and 

 would thus act as an opponens of the great toe if the great toe 

 were present.
