R. cavdalis (Fig. Trnp. ca.), a small ramulus, passes caudad of the pro- 

 cess, bends caudad, and terminates in the integument over the forehead ; 

 it anastomoses with the auriculotemporal nerve. 



N. malaris is the lateral ramus of the orbital ; its course is direct to the 

 malar foramen (a small foramen in the malar bone just dorsad of the ce- 

 phalic end of the zygomatic process) ; it penetrates this foramen, lies in a 

 groove entad of the orbicular muscle, which it perforates near the angle of 

 the eye, and is distributed to the ventral lid and cheek over the malar 

 bone (this is the subcutaneous malar nerve of anthropotomy) ; its termi- 

 nal filaments reach the labial plexus. 



N. palatinus cephalicus (Fig. Pit. ce. ) : About the middle of the rete 

 carotideum three rami are detached from the ventral surface of the maxil- 

 lary nerve ; these remain in the sheath for several mm. The cephalic 

 ramus (Fig. Pit. ce.) lies ventrad of the palatine artery and enters the 

 palatine foramen (the dorsal end of the posterior palatine canal) ; it sends 

 an anastomotic filament to N. palatinus caudalis (Fig. Pit.). Just cen- 

 trad of the palatine foramen (Fig. Fm. pit. p.) a large accession is received 

 from the sphenopalatine ganglion (Sph.). 



(In some cases a fascicle from this nerve enters a small foramen just cau- 

 dad of the posterior palatine foramen, and, following a canal in the pala- 

 tine bone, joins the nerve at the posterior palatine foramen). Peripherad 

 of this foramen (Fm. pit. p.) the nerve lies close to the hard palate, and 

 joins the nasopalatine nerve at the anterior palatine foramen (Fm. pit. a. ) ; 

 it sends numerous filaments to the ruga upon the roof of the mouth and 

 to the adjacent mucosa. 



G-. spheno-palatinum (Sph.), Ganglion of Meckel : This ganglion is 

 located just caudad of the palatine and the spheno-palatine foramina ; its 

 cephalic angles or prolongations enter these foramina (Fig.) : it is flesh- 

 colored, 6 mm. X 2 mm., flattened, irregular in outline, the mesal border 

 slightly concave ; the lateral border is irregular by reason of the attach- 

 ment of nerves ; its roots are two large rami (N. N. sph. pit. Fig. root) of 

 the maxillary nerve, which take origin just peripherad of the cephalic 

 palatine nerve, and are included in the common sheath with that nerve 

 for 2-4 mm. ; the roots are inserted into the lateral angle of the ganglion 

 about 1 mm. apart. 



Relations: This ganglion (Sph.) is related with the maxillary nerve by 

 two roots ; with the carotid plexus (N. sympathicus) by two filaments 

 (Sym.) from the caudal border between the roots and the vidian nerve ; 

 with the cephalic palatine by a large fascicle from the cephalo-lateral 

 angle. It is the origin of the nasopalatine nerve (N. pit.) at the spheno- 

 palatine foramen ; the origin of N. pharyngeus near the vidian nerve ; of 

 N. palatinus caudalis at the lateral border caudad of the palatine foramen, 

 and of N. vidianus at the meso-caudal angle. 



N. palatinus caudalis (posterior) : This nerve (Fig. Pit.) takes its origin 

 from the lateral border of the spheno-palatine ganglion justcentrad of the 

 palatine foramen ; its course is ventrad and caudad ; 2-5 mm. lrona the
