339. The Salivary Glands, Glandulae salivales. 



On each, side there are three salivary glands, namely: 

 The parotid gland, Glaiidula parotis, lying in front of and below 

 the ear, fills out the angle between the ramus of the lower jaw, the 

 mastoid process and the external auditory meatus, and extends over the 

 anterior surface of the Masseter muscle. Its chief excretory duct, Stenson's 

 duct, Ductus Stenonianus, runs forwards parallel to the zygomatic arch, 

 pierces the buccinator muscle, and opens on the inner surface of the 

 cheek, opposite the first or second upper molar tooth. Frequently an iso- 

 lated small Parotis accessories lies upon Stenson's duct. 



The submaxillary gland, Glandula submaxillaris, lies partly 

 beneath the mylo-hyoid muscle in the triangular space between the lower 

 border of the inferior maxilla and the digastric muscle (M. biventer maxillae) . 

 Its excretory duct, Wharton's duct, Ductus WJiartonianus, opens at the 

 side of the Fraenulum linguae on the summit of a small papilla, Caruncula 

 suUingualis.
