ANGIOLOGY. 



addition to twigs supplied to the submaxillary gland and facial 

 muscles, five branches are given off, the pharyngeal, lingual, sub- 

 lingual, and inferior and superior labial or coronary arteries. 



The lyharyii'igeal, or ascending pharyngeal, is given off near 

 the origin of the glosso-facial, passing obliquely upwards between 

 the cornu of the os hyoides and the hyo-pharyngeal muscle. It 

 takes a flexuous course towards the pterygoid process, terminating 

 in the velum palati, and giving off ascending and descending 

 branches to the walls of the pharynx.

The lingual, almost as large as the parent artery, originates 

 near the cornu of the hyoid bone, passes under the hyo-glossus 

 brevis in company with the glosso-pharyngeal nerve, crosses the 

 corniculum, and is thence prolonged almost to the free extremity 

 of the tongue in a very tortuous manner. This artery, sometimes 

 called the ranine, is buried in the interstices between the hyo- 

 glossal and genio-hyo-glossal muscles in company with branches 

 of the lingual and hypo-glossal nerves. 



The siiblingiud artery is given off at the anterior extremity of 

 the submaxillary gland, passing to the external surface of the 

 mylo-hyoideus, on which it runs foi wards, and along the inferior 

 surface of the sublingual gland, supplying it as well as the genio-
