252 THE TEMPORAL ARTERY. 



of the cavity of the tympanum, with a small twig derived from 

 the artery of the dura mater. When it has arrived behind the 

 ear, the Posterior Auricular Artery terminates upon the exter- 

 nal ear and the parts contiguous to it. 



Distribution of the Branches of the External Carotid Artery, 

 after Sir Charles Bell. (See Plate III., facing page 252.) 



A. The Common Carotid Artery. 



B. The Internal Carotid Artery, or Artery of the Cerebrum, 

 c. The External Carotid Artery. 



D. The Lower Thyroid Artery, being a branch of the Subclavian Artery. 



E. The Upper Thyroid Artery, being the first branch of the Carotid. 



Branches of the External Carotid Artery. 



1 . The Lingual Artery. 



2. The Facial Artery, or Labial Artery. 



3. The Submental Artery. 



4. The Upper and Lower Coronary Arteries. 



5. The Inosculations of the extreme Branches of the Facial Artery, with 

 the Ophthalmic Artery. 



6. The Occipital Artery. 



7. The place where it frequently sends down inosculations to the verte- 

 bral artery. 



8. The Lesser Posterior Artery of the Ear. 



9. A Branch sometimes called Posterior Temporal Artery. 



10. Posterior Artery of the Ear, or Stylo-mastoid. 



11. The continued Branch of the External Carotid, sometimes called the 

 Temporal Artery ; it divides into the submaxillary and proper temporal 

 artery. 



12. The Internal Maxillary Artery. See the distribution of this artery in 

 the next Plate, Fig. I. 14, and Fig. II. 



13. The Transverse Artery of the Face. 



14. The Temporal Artery, dividing into anterior and posterior temporal arte- 

 ries. There are other branches less superficial. The deep Temporal is 

 a branch of the Internal Maxillary. 



7. The Temporal Artery 



Is considered as the continuation of the external carotid, 

 because it preserves the direction of the main trunk ; although 

 the internal maxillary is larger. 



After parting with the internal maxillary it projects out-
