the length and breadth of their attachments have been charted, 

 and study the following joints. 



Intertarsal Articulations (Articulationes intertarseae). 



Taloealcaneonavicular Articulation (Articulatio talocalcaneonavicularis) . 



This is the more anterior of the two separate joint-cavities 

 which exist between the talus on the one hand and the navicular 

 bone and the calcaneus on the other. The posterior of the two 

 joint-cavities is called the articulatio calcanea. (See Spalteholz, 

 Fig. 271.)
