218 MAMMALIA. 



the exterior of the orbit, and gives branches to the superficial muscles and 

 integuments on the temple ; the greatest part of it is then distributed on the 

 horn. Two other branches from the Gasserian ganglion pass outwardly in a 

 canal on the inner plate of the frontal sinus to the junction of this with the 

 outer plate, and near the insertion of the horn. 



10. Second trunk of the fifth, passing out at the infra-orbital foramen to divide into 



branches, to be distributed on the upper lip, the outer side of the nose, and 

 the Schneiderian membrane at the inferior part of the nose. 



11. Lateral nasal nerve of the second trunk of the fifth, receiving the Vidian nerve, 



and passing into the nose to the Schneiderian membrane. 



12. Palatine branch of the second trunk of the fifth, communicating with the lateral 



nasal, and terminating on the palate. 



13. Third trunk of the fifth. 



14. Buccal nerve from the third trunk of the fifth; it gives a branch to the 



external pterygoid muscle; it then passes over the inner surface of this 

 muscle ; it emerges from underneath the anterior edge of the masseter, and 

 divides into branches, which terminate on the buccinator muscle and skin of 

 the face ; it forms considerable communications with branches of the hard 

 portion of the seventh. 



15. A branch dividing into the inferior dental and gustatory nerves; branches are 



also given to the circumflex muscle of the palate, and the internal pterygoid 

 muscle. 



16. Inferior dental nerve ; it sends off close to the jaw the mylo-hyoideal nerve, 



which passes down to supply the mylo-hyoideal muscle, and the maxillary 

 portion of the digastric ; it then enters the jaw, supplies the teeth, and 

 emerges near the chin to divide into branches, communicate with branches of 

 the hard portion of the seventh, and terminate in the lower lip. 



17. Gustatory nerve ; it receives the cord of the tympanum ; it passes forward and 



divides into branches, which ascend to the anterior portion of the surface of 

 the tongue, between the insertions of the genio-hyo-glossal and lingual 

 muscles ; it gives branches also to the salivary glands, and the membrane of 

 the mouth connecting the lower jaw and side of the tongue.
