the outer angle of the orbit, and supply the outer part of the 

 orbicularis palpebrarum. They form communications with the 

 lachrymal branch of the ophthalmic, with the malar of the orbital, 

 and with the infra-orbital, both these latter being branches of the 

 superior maxillary, and all of them being sensory nerves. 



The infra-orbital branches, the largest of this group, pass forwards 

 to the region between the lower margin of the orbit and the upper 

 lip. They supply the lower part of the orbicularis palpebrarum.

the muscles of the nose, the elevators of the upper lip, the upper part 

 of the orbicularis oris, and the buccinator. They communicate 

 with the following .sensory nerves : the infra-orbital of the superior 

 maxillary, the infratrochlear of the nasal, and the terminal 

 cutaneous branch of the nasal, from the ophthalmic. The com- 

 munications with the infra-orbital nerve take place under cover 

 of the levator labii superioris muscle, and form a somewhat intricatej 

 plexus, called the infra-orbital plexus. 



The cervico-facial division likewise furnishes three sets of I
