The spJieno-maxillary fissure connects the zygomatic, tem- 

 poral, and spheno-maxillary fossae, and transmits the infraorbital 

 artery, ascending branches of MeckePs ganglion, the superior 

 maxillary nerve, and its orbital branch. 



It is bounded above by great wing of sphenoid, below by 

 superior maxilla and part of palate bone ; internally it opens into 

 ptery go-maxillary fissure, and externally part of malar bone.
