The Facial Artery. Figs. 2, 3, 14. 



On the face. The facial artery comes into the face from 

 the neck over the lower border of the inferior maxillary 

 bone, lying in the facial notch just at the junction of the 

 ramus and body, at the anterior border of the masseter 

 muscle. 



It takes a very tortuous course around the angle of the 

 mouth and along the side of the nose to terminate at the 

 inner angle of the eye. 



In its course it passes under the platysma, zygomatic 

 major and minor, the levator labii superioris, and levator 

 labii superioris alaequae nasi. 



The facial vein lies behind the artery. 



Branches of the Facial Artery. On the Face. 



(i) Muscular, to the masseter and buccinator muscles. 

 The masseteric branches anastomose with the transverse 

 facial and muscular branches from the internal maxillary. 

 The buccal, with the same, and also with the infra-orbital, 

 from the internal maxillary. (2) The inferior labial. Its 

 course is forward under the depressor anguli oris and mid- 

 way between the border of the lip and the chin, to supply 

 the muscles of the lower lip. It anastomoses with the 

 facial branches above and below itself and across the median 

 line. 



All the anterior facial branches anastomose across the 

 median line with corresponding arteries from the opposite 

 facial, as well as with the arteries next above and below. 

 Exception : the coronary arteries do not anastomose with 

 each other, except at the angle of the mouth. (3) The 

 inferior coronary. Extends forward beneath the depressor
