320 MUSCLES OF THE FAUCES. 



Salpingo-Pharyngenus, (from salnd^ trumpet,') 



Of Albinus, is composed of a few fibres of this muscle, which 

 Arise from the anterior and lower part of the cartilaginous 

 extremity of the Eustachian tube ; and are, 



Inserted into the inner part of the last-mentioned muscles. 

 Use. To assist the former, and to dilate the mouth of the tube. 

 The one in the middle is the 



Azygos Uvula, 



Arises, fleshy, from the extremity of the suture which joins 

 the palate bones, runs down the whole length of the velum and 

 uvula, resembling a small earth-worm, and adhering to the ten- 

 dons of the circumflexi. Two are frequently met with. 



Inserted into the apex of the uvula. 



Use. Raises the uvula upwards and forwards, and shortens it. 



Muscles situated on the posterior part of the Pharynx. 

 Of these there are three pair : 



1. Constrictor Paryngis Inferior, 



Arises, from the side of the thyroid cartilage, near the attach- 

 ment of the thyroideus and thyro-hyoideus muscles ; and from 

 the cricoid cartilage, near the crieo-thyroideus. This muscle is 

 the largest of the three ; and is 



Inserted into the white line, where it joins with its fellow : 

 the superior fibres running obliquely upwards, covering nearly 

 one half of the middle constrictor, and terminating in a point ; 

 the inferior fibres run more transversely and covers the beginning 

 of the oesophagus. 



Use. To compress that part of the pharynx which it covers, 

 and to raise it with the larynx a little upwards. 



2. Constrictor Pharyngis Medius, 



Arises from the appendix of the os hyoides, from the cornu 

 of that bone, and from the ligament which connects it to the 

 thyroid cartilage ; the fibres of the superior part running
