External Carotid Artery. — The external carotid artery is one of 

 the terminal branches of the common carotid, the other being the 

 internal carotid artery. The two vessels are called external and 

 internal, the one because it is extracranial in its distribution, and 

 the other because it is intracranial. 



The external carotid artery, as regards position, is the internal 

 of the two vessels, and it lies anterior to, and nearer the median line 

 than, the internal carotid. It extends from a p3int on a level with

the upper border of the thyroid cartilage to a point immediately 

 behind the neck of the inferior maxilla, where it divides, in the 

 substance of the parotid gland, into the superficial temporal and 

 internal maxillary arteries. It is about 2h inches in length, and 

 its direction is upwards and slightly backwards. At first the 

 artery lies in the carotid triangle, and is comparatively super- 

 ficial. As it leaves this triangle it is more deeply placed, being
