5. The supraorbital, with the supraorbital nerve. 



6. The infraorbital, with the infraorbital nerve. 



7. The mental, with the mental nerve. 



8. The facial artery (Fig. 17) crosses the mandible in front oi the 

 masseter muscle. It is surrounded by some very delicate sympathetic nerves,

which can be demonstrated, if you remove all the fat, with ether, and permit the 

 ether to evaporate. These nerves are the ncri'i uiolles. They regulate blushing.

2. The superior coronary, between mucous membrane and orbicularis oris. 



3. The inferior labial, under the muscles of the chin.
