THE SALIVARY GLANDS 6i 



inflammatory material. Upon examination of the interior of the buccal 

 cavity a large elevation is seen on the floor of the mouth near the 

 frsnum linguas. 



Owing to the close proximity of the gland to the pharyngeal wall, 

 as the gland enlarges it presses the wall of the pharynx inwardly 

 and marked dyspncEa results. 



The condition is usually relieved by pinching up with the forceps 

 a small portion of the buccal mucous membrane near the barb, and 

 removing it with the scissors. 



The Duct of Wharton 



This is the excretory duct of the submaxillary gland. It is formed 

 along the anterior border of the gland by the union of ducts of the 

 numerous lobules of v^'hich the gland is composed. The duct leaves the 

 gland at its anterior extremity, and here the submaxillary artery crosses 

 it outwardly. It next runs along the deep face of the mylo-hyoid 

 muscle, and between this muscle and the hyo-glossus and stylo-glossus. 

 It passes between the genio-glossus muscle and the sublingual gland, and 

 it ultimately communicates with the mouth on the summit of the barb, 

 which is a little papilla flattened superiorly and placed near the 

 fraMium lingua-. 



The wall of Wharton's Duct is not so strong as is that of the 

 Duct of Stenson. It is devoid of circular elastic fibres, and its outer 

 connective tissue coat is much thinner. 



The Sublingual Gland 



This is smaller than the submaxillary gland. It is also elongated, 

 flattened from side to side, and it extends from opposite the fifth molar 

 tooth, forwards to the symphysis of the inferior maxilla. Its position is 

 indicated in the cavity of the mouth by an elevation of the buccal 

 mucous membrane, which elevation is situate to the side of the franum
