FRONT ASPECT OF THE SKULL. 



THE outline of the skull when seen from the front (Fig. 384) is 

 nearly circular. It is made up of the outlines of the frontal part of 

 the cranial vault, of the postorbital processes, of the zygoma, and of 

 the horizontal rami of the lower jaw. 



The bones of the face form the greater part of the front aspect of 

 the skull ; of the cranial bones the frontals are seen at the upper part,
