FIFTH PAIR OF NERVES. 

 Fig. 145.* 



The inferior branch supplies the lower surface of the gland and con- 

 junctiva, and terminates in the integument of the upper lid communi- 

 cating with the facial nerve. 



The Nasal nerve (naso-ciliaris) passes forwards between the two 



* A diagram, shewing the fifth pair of nerves with its branches. 1 . The 

 origin of the nerve by two roots. 2. The nerve escaping from the crus cere- 

 beUi. 3. The Casserian ganglion. 4. Its ophthalmic division. 5. The frontal 

 nerve, giving off the supra- trochlear branch, and escaping on the forehead 

 through the supra-orbital foramen. 6. The lachrymal nerve. /. The nasal 

 nerve, passing at 8 through the anterior ethmoidal foramen, and giving off the 

 infra-trochlear branch. 9. The communication of the nasal nerve with the 

 ciliary ganglion. 10. A small portion of the third nerve with which the gan- 

 glion is seen communicating ; the ganglion gives off the ciliary branches from 

 its anterior aspect. 11. The superior maxillary nerve. 12. Its orbital branch. 

 13. The two branches communicating with MeckePs ganglion ; the three 

 branches given off from the lower part of the ganglion are the posterior palatine 

 nerves. 14, 14. The superior dental nerves, posterior, middle, and anterior, 

 forming by their communications the superior maxillary plexus. 15 The infra- 

 orbital branches distributed upon the cheek. 16. The 'inferior maxillary nerve. 

 17. Its anterior or muscular trunk. 18. The posterior trunk ; the two divisions 

 are separated by an arrow. 19 The gustatory nerve. 20. The chorda tym- 

 pani joining it at an acute angle. 21. The sub maxillary ganglion. 22. The 

 inferior dental nerve. 23. Its mylohyoidean branch. 24. The auricular nerve, 

 dividing behind the articulation of the lower jaw, to reunite and form a single 

 trunk. 25. Its branch of communication with the facial nerve. 26. Its tem- 

 poral branch.
