350 THE ARTICULATIONS, OR JOINTS 



The dorsal ligaments (ligamenta navicularicuneiformia dorsalia) (Figs. 274 

 and 276) are small, longitudinal bands of fibrous tissue arranged as three bundles, 

 one to each of the cuneiform bones. That bundle of fibres which connects the 

 scaphoid with the internal cuneiform is continued around the inner side of the 

 articulation to be continuous with the plantar ligament which connects these 

 two bones. 



The plantar ligaments (ligamenta navicularicuneiformia plantarid] (Fig. 279) 

 have a similar arrangement to those on the dorsum. They are strengthened by 

 processes given off from the tendon of the Tibialis posticus. 



Synovial Membrane (Fig. 280). The synovial membrane of these joints is part of the great 

 tarsal synovial membrane. 



Movements. The movements permitted between the scaphoid and cuneiform bones are 

 limited to a slight gliding upon each other. 



6. THE ARTICULATION OF THE SCAPHOID WITH THE CUBOID (ARTICULATIO 



CUBONAVICULARIS). 



The scaphoid bone is connected with the cuboid by 



Dorsal. Plantar, and Interosseous Ligaments. 



The dorsal ligament (ligamentum cuboideonaviculare dorsale) (Fig. 277) con- 

 sists of a band of fibrous tissue which passes obliquely forward and outward 

 from the scaphoid to the cuboid bone. 



The plantar ligament (ligamentum cuboideonaviculare plantare) consists of a 

 band of fibrous tissue which passes nearly transversely between these two bones. 



The interosseous ligament (Figs. 276 and 280) consists of strong transverse 

 fibres which pass between the rough nonarticular portions of the lateral sur- 

 faces of these two bones. 



Synovial Membrane (Fig. 280). The synovial membrane of this joint is part of the great 

 tarsal synovial membrane. 



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

 to a slight gliding upon each other. 



7. THE ARTICULATIONS OF THE CUNEIFORM BONES WITH EACH OTHER OR 

 THE INTERCUNEIFORM ARTICULATIONS (Fig. 276). 



These bones are connected by 



Dorsal, Plantar, and Interosseous Ligaments. 



The dorsal ligaments (ligamenta intercuneiformia dorsalia) consist of two bands 

 of fibrous tissue which pass transversely, one connecting the internal with the 

 middle cuneiform, and the other connecting the middle with the external cunei- 

 form. 



The plantar ligaments (ligamenta intercuneiformia plantaria) have a similar 

 arrangement to those on the dorsum. They are strengthened by the processes 

 given off from the tendon of the Tibialis posticus. 



The interosseous ligaments (ligamenta intercuneiformia interossea) consist of 

 strong transverse fibres which pass between the rough nonarticular portions of 

 the lateral surfaces of the first and second and the second and third cuneiform 

 bones. The outer portion of the third cuneiform is attached to the cuboid by 

 the ligamentum cuneocuboideum interosseum.
