ria) (O. T. socia parotidis). Follow the retromandibular proc- 

 ess of the gland (processus retromandibularis) in behind the 

 mandible. How is the pocket in which the parotid gland is con- 

 tained separated from that in which the subniaxillarv gland is 

 situated? Pick away the parotid gland bit by bit, in order to 

 study the blood-vessels and nerves of the region, many of which 

 pass directly through the gland-substance. 



Superficial Blood-vessels and Nerves of Face. (Vide Figs. 87. 873, 

 and 105.) 



Arteries. 



(a) External carotid (A. carotis externa). 



(aa) Superficial temporal (A. temporalis superficial). 



(aaa) Parotid rami (rami parotidei). 



(aab) Transverse artery of face (A. transversa faciei). 



(aac) Anterior auricular rami (rami auricula res ante- 



riores). 



(aad) Middle temporal artery (A. temporalis media). 



(aae) Zygomatico-orbital artery (A. zygomatico-orbi- 



talis). 



The terminal rami have already been studied in the 

 dissection of the scalp. 



(ab) Internal maxillary artery (A. maxittaris interna). 



Its branches cannot yet be seen. 



(ac) External maxillary artery (A. maxiOaris externa) (O. T. 



facial artery). 



(oca) Inferior labial (A. labialis inferior). 

 (atA) Superior labial (A. labial is superior), 

 (ace) Angular artery (A. angularis). 

 Veins. (Cf. Spalteholz, Figs. 487, 488.) 



(a) Posterior facial vein (V. facialis posterior). 



(aa) Superficial temporal vein (V. temporalis superficialis) .
