INTERTARSAL ARTICULATIONS 



357 



The Dorsal Ligament (ligamentum cuboideonamculare dorsals} . The dorsal ligament 

 extends obliquely forward and lateralward from the navicular to the cuboid bone 

 (Fig. 355). 



The Plantar Ligament (ligamentum cuboideonaviculare plantare}. The plantar 

 ligament passes nearly transversely between these two bones (Fig. 358). 



The Interosseous Ligament. The interosseous ligament consists of strong trans- 

 verse fibers, and connects the rough non-articular portions of the adjacent surfaces 

 of the two bones Fig. 360) . 



Synovial Membrane. The synovial membrane of this joint is part of the great tarsal synovial 

 membrane (Fig. 360). 



Movements. The movements permitted between the navicular and cuboid bones are limited 

 to a slight gliding upon each other.

Intercuneiform and Cuneocuboid Articulations. The three cuneiform bones and 

 the cuboid are connected together by dorsal, plantar, and interosseous ligaments. 



The Dorsal Ligaments (ligamenta intercuneiformia dorsalid). The dorsal liga- 

 ments consist of three transverse bands: one connects the first with the second 

 cuneiform, another the second with the third cuneiform, and another the third 

 cuneiform with the cuboid. 



The Plantar Ligaments (ligamenta intercuneiformia plantaria), The plantar liga- 

 ments have a similar arrangement to the dorsal, and are strengthened by slips 

 from the tendon of the Tibialis posterior. 



The Interosseous Ligaments (ligamenta intercuneiformia inter ossea}. The inter- 

 osseous ligaments consist of strong transverse fibers which pass between the rough 

 non-articular portions of the adjacent surfaces of the bones (Fig. 360).
