basion (ba) 



condylion laterale (cdl) f 

 condylion mediale (cdm) f 

 coronale (co) f 



The meeting place of the coronal and sagittal 



sutures; that is, the point of meeting of the two 



parietals with the frontal. 



The median point in the anterior margin of the 



occipital foramen. 



The most lateral point on the surface of the condyle 



of the mandible. 



The most medial point on the surface of the condyle 



of the mandible. 



The two points in the lateral margins of the frontal 



which mark the termini of the maximum breadth 



of this bone. These points n jgt be symmetrically 



placed with reference to the median line.

coronion (cr) f 

 dacryon (d) f 



ectoconchion (ec) f 



ectomolare (ecm) f 



The point of the coronoid process of the mandible. 

 A point just within the inner margin of the orbit, 

 where the lacrimo-maxillary suture meets frontal 

 bone (Fig. 24). 



The point where the orbital length line, parallel 

 to the upper border, meets the outer rim. This 

 line must be perpendicular to that measuring the 

 orbital breadth. 



The most lateral point on the outer surface of the 

 alveolar ridge, opposite the middle of the second 

 upper molar tooth; used in taking the maxillary 

 breadth. (Fig. 25, x).
