20, Rig-lit Malar Bone, 

 Os zygomaticum, 



from the inner side. 



The malar bone has 3 processes: the strongest frontal pro- 

 cess, Processus frontalis, articulating with the frontal bone; the zy go- 

 mat ic process, Z'wrxxws zygonmttais, which forms with the zygomatic 

 process of the temporal bone the Arcus zygomaticus, and the smallest 

 sphenoidal }> r o c e s s, P-rocessus splimoidalis, which, looking backward, 

 articulates with the anterior border of the orbital surface of the great 

 wing of the sphenoid bone. Body is that portion which articulates with 

 the zygomatic process of the superior maxilla. (This part is also called 

 maxillary process.) 



The surfaces are the facial (external), temporal (internal), 

 and orbit a 1. From the orbital surface to the facial surface runs the Canalls 

 zygomaticus facialis, with an accessory canal to the temporal surface. Behind 

 this canal there is a second, leading from the orbital cavity into the tem- 

 poral fossa, the Canalis zycjomaticus temporalis. (These canals are also 

 called temp oro -malar canals.) 



The m ci 1 a r bone articulates with 4 bones : with 3 cranial bones, the 

 frontal, sphenoid and temporal, and 1 bone of the face, the superior maxilla.
