the Bpheno-maxillary fossa where it is connected with Meckel's ganglion. As 

 it passes forward it is called the infratrochlear nerve and passes in the groove on 

 the floor of the orbit and comes out on the face through the infraorbital foramen. 

 This foramen is beneath the Levator labii superioris and the Levator anguli- 

 oris. The nerve in this position anastomoses with the seventh to form a plexus
