THE VESSELS. 303 



Terminal branches. 



a. Art. meningea posterior, ramify in the gangl. suprem. N. sympathici, Nn. 

 vagus, glossopharyng., hypoglossus, and enters through foram. jugulare to the 

 dura mater in the fossa occipital, inferior; gives a branch which anastomoses 

 with Art. cervical, adscend. 



b. Earn, pharyngeus, continuation ofpharyng. ascend. Course : before the 

 carotis interna, and divides at the basis cranii, behind the pharynx into seve- 

 ral branches, which are reflected and terminate on the tuba Eustackii, and in 

 the muscles of the pharynx. 



546. Terminal branches of the Carotis externa. 



7. Temporalis (superficialis), the temporal artery. Origin: behind collum 

 condyli of the lower jaw and before the external auditory meatus. Course : 

 directly upwards, before the ear, over the root of the process, zygomatic. of the 

 temporal bone, then in a serpentine direction as far as the centre of the tem- 

 poral region (or one inch above the zygoma) where it divides. Position : at 

 first upon the maxillary articulation covered by Parotis, then by the skin and 

 fasc. parotidea, only, above/ascia temporalis. 



Anterior collateral branches. 



a. Transversa facei, arises (frequently from carotis externa} immediately at 

 the collum condyli, passes transversely over this and m. masseter, covered by 

 Parotis, underneath the zygoma (inch and a half) and above ductus Stenonia- 

 nus (parallel with it) on to the face ; sends a branch for the maxillary articu- 

 lation, for the duct. Stenon., several r. masseterici and ramifies on the ante- 

 rior border of m. masseter into cutaneous branches for the cheeks into muscular 

 branches for mm. zygomaticus major, orbicular, palebr., levat. labii super.; 

 anastomoses between artt. temporal, and buccalis, infraorbital. and max- 

 illaris externa. 



b. Ram. orbicularis, not always present, arises above the zygoma, placed 

 behind m. orbicularis, supplies these and anastomoses with art. palpebral. 

 super, (see Art. ophthalm.) 



Posterior branch. 



c. Auriculares anteriores; the inferior for the lobule of the ear; the central 

 for the auditory meatus ; the superior for helix, m. attrahens and atlollens au- 

 ricula. 



Internal branch. 



d. Art. temporalis media (s. prof undo), arises close above the zygoma, enters 

 into the m. temporal, through the deep layer of fasc. temporal, and anastomoses 

 with the temporal artery of Art. maxillaris interna. 



Terminal branches. 



e. Earn, frontalis B. anterior passes in a curve towards the forehead, and 

 anastomoses with art. frontalis, supraorbilal. and ram. frontal, of the other 

 side.
