temporal, upwards, to the posterior border of the last, and ramifies in these 

 and the periosteum ; anastomosing with Artt. temporal, profund. anter. and 

 media, and gives, sometimes, Artt. masseterica and buccinatoria. 



f. Masseterica, small, passes over incisura semilunar. outwards to the mas- 

 seter m. 



g. PterygoidecB for mm. pterygoidei; some from the Art. c. and e. ; ptery- 

 goid. extern, gives off, sometimes, a meningea parva through foram. ovale. 



548. B. Arising in the neighbourhood of the tuber 



Maxillce superioris. 



h. Buccinatoria, small, passes in a serpentine course from behind forwards, 

 between the ramus of the lower jaw and m. pterygoid. intern., and is lost in m. 

 buccinatorius . 



i. Temporalis profunda anterior, passes to the anterior border of m. tempo- 

 ralis (behind the malar- sphenoidal suture) upwards, is lost in the last, and 

 sends branches into the fat of the orbit. 



k. Dentalis superior (posterior) passes downwards in a very serpentine 

 manner to the posterior surface of the upper jaw, below proc. zygomat. upon 

 the anterior surface of the former, gives branches to the gums, periosteum, 

 and the superior alveolus, and enters, divided into several branches, through 

 foramm. alveolaria postt. into the upper jaw for the (superior) molar teeth. 

 Separate branches pass to the mucous membrane of the antrum. 



1. Infraorbitalis, arises behind fissura orbital, infer., and enters immedi- 

 ately into the canal, infraorbitalis , passes through it, and appears at its ante- 

 rior opening on the face, where the artery ramifies in branches for the exte- 

 rior and mucous membrane of the cheeks, gums, the corner and incisor teeth, 

 and for the nose, and anastomose with Artt. maxillaris externa and facialis 

 transversi. 



Branches out ofcanalis infraorbitalis. 



1. Earn, orbitalis, passes with a branch forwards to the inferior eyelid ; 

 with another inwards for ram. palpebral. infer, of art. ophthalm. 



2. Ram. dentalis anterior, passes downwards between the plates of the 

 upper jaw (anterior wall) to the roots of the cuspids and incisor teeth. 



549. C. Arising in ihe fossa spheno-maxillaris. 



m. Vidiana, passes backwards through canal Vidianus to the superior wall 

 of ihe pharynx and to the tuba Eustachii; arises also from the following (as 

 pharyngea supremo). 



n. Pterygo-palatina s. palatina superior, internal and below the former, de- 

 scends through can. pterygo-palatinus behind the upper jaw, through and out 

 of foram. palati. anterius [posterius] and passes in a serpentine course close 

 to the alveolus forwards on the inferior surface of the palatine vault, until, 

 forming a curve, it meets with the one of the other side at the canal, incisivus. 

 Quite above it gives off 



1. Ramuli palatini; going through canales palatinipost. to the soft palate.
