crotapliite muscle in the temporal fossa ; 6 — anterior 

 deep temporal, in the crotaphite also, and the adipose 

 tissue of the fossa; 7 — ophthalmic, from the ocular 

 sheath, return into the cranium through the orbital 

 foramen, and divides into meningeal and nasal branches. 

 The orbital portion gives off muscular branches, cen- 

 tral artery of the„ reiinat ciliary, supra orbital and 

 lachrymal ; the cranial portion, the cerebral branches ; 

 8 — buccal, supplies the molar glands, the buccinator 

 and the maxillo-labialis rnuscles; 9 — staphyline, to the 

 velum palati ; 10 — superior dental, goes to the supe- 

 rior raaxillo-dental canal, and distributed like the infe- 

 rior dental; 11 — nasal, runs through the nasal foramen 

 into the nasal fossa, where it ends by external and 

 internal branches, ^j ^ ' " '^z; 



Palato-labial, passesrrom the inaxfflai^ hiatus to ^ 

 tlie palatine canal, through it to the front part of the 

 palate, to the incisive foramen where it anastamoses 

 with the opposite one, forming a single trunk, which, 

 passing through the incisive foramen, reaches the upper 

 lip and terminates by anastamoses witli the superior 

 coronary. 



Veins. — Three principal trunks : superficial temporal, 

 internal maxillary and sinuses of the encephalic dura 

 mater ; they form the root of the jugular.
