The nasal branch passes inward and upward under cover of the Levator 

 labii superioris to supply the skin on the posterior part of the lateral aspect of 

 the nose. It joins with the nasal branch of the ophthalmic. 



The labial branch descends beneath the Levator labii superioris to be 



distributed to the integument of the upper lid, also to mucous membrane of 



mouth and to labial glands.

III. The inferior maxillary division of the fifth, the mandibular branch, 



is a compound nerve after it passes through the foramen ovale. It is the largesl 

 branch of the fifth nerve. Its sensory portion comes from the Gasseriau gang- 

 lion. This compound nerve, immediately after it leaves the foramen ovale, 

 divides into anterior and posterior branches. The main trunk before it divides 

 has the External pterygoid muscle and optic ganglioD external, and the Tensor 

 palati muscle internal, and in front of it is the posterior border of the Internal 

 pterygoid muscle, and behind is the middle meningeal artery. The branches 

 from the trunk are (1) a recurrent which passes backward with the middle 

 meningeal artery through the foramen spinosum to supply the dura mater. 



2. The nerve to the Internal pterygoid muscle. This nerve sends a motor 

 branch to the optic ganglion. The anterior division of the main nerve is small
