branch, which runs along the upper border of the hyoid bone, (2) dorsalis 

 lingile branch, which passes upward under the Hyo-glossus muscle to the 

 dorsum of the tongue, (3) a sublingual branch, which passes on the Genio- 

 hyo-glossus muscle to the sublingual gland, (4) the ranine branch. 



The fascial artery (Plate CXVI.) comes from the external carotid just above 

 the origin of the lingual artery and passes obliquely upward under the Digastric 

 and Stylo-hyoid muscles, it then passes forward in a groove on the posterior 

 surface of the submaxillary gland. This much of the artery is called the cer- 

 vical portion. It then passes upward over the lower jaw at the anterior margin 

 of the Masseter muscle to the angle of the mouth. This portion of the artery 

 is called the facial portion. It now runs upward along the nose and ends at the

inner canthus of the eye. This portion of the artery is called angular por- 

 tion. The facial artery lies just under the superficial muscles and has a very 

 tortuous course. 



The branches of the facial artery given off in the neck arc (I) [NFERIOR 

 or ascending palatine, which passes between the Stylo-glossus and Stylo- 

 pharyngeus muscles to the outer side of the pharynx where it divides into two 

 branches, one of which runs through the Superior constrictor muscle and the 

 other branch passes over this muscle. (2) The tonsillar branch which 

 passes between the Internal pterygoid and Stylo-glossus muscles and after 

 piercing the Superior constrictor passes to the tonsil. (3) The submaxillary
