Joint of the Jaw. 



155 



2O7. Jaw joint of right side, articulatio mandibularis, 



from without; somewhat schematic. 



The position of the lower jaw when the mouth is shut is indicated in black; when the 



mouth is wide open in red. 



When the mouth is closed the capitulum of the processus condyloideus is in contact 

 with the posterior slope of the tuberculum articulare and the anterior portion of the fossa 

 mandibularis; when the mouth is wide open it stands somewhat in front of the deepest 

 point of the tuberculum articulare; in both cases, however, the capitulum is separated 

 from the points of the temporal bone mentioned by the discus articularis.
