CONTRIBUTION TO THE ANATOMY OF THE ADULT 

 HUMAN SALIVARY GLANDS 



By Churchill Carmalt 



The adult human salivaty apparatus is structurally composed of 

 two separate and distinct glandular areas. In one of these divisions 

 the individual glandular anlages are united to form definite major 

 glands, with distinct ducts, conveying the secretion of each gland to 

 a terminal orifice. This group comprises the submaxillary and greater 

 sublingual glands in the alveolingual field, and the parotid in the area 

 of the superior alveobuccal sulcus. 



The second group is characterized by the retention of a more primi- 

 tive type of salivary organization. Certain areas of the oral, faucial, 

 palatine, pharyngeal, and alveobuccal mucous membrane carry the 

 minute orifices of numerous small separate and distinct glands. This 

 glandiferous mucosa is topographically divided into districts. Thus 

 the group of the lesser sublingual, or — in Chievitz's sense — "alveo- 

 lingual" glands occupies the lateral district of the oral floor proper. 

 Similar separate elements, mesad of the line of the submaxillary duct, 

 form in all probability the Blandin-Nuhn or "apical" gland of the 

 tongue, and the so-called " gland of Weber." 



Further caudad this type of numerous separate minute glands, 

 each with its individual orifice, invades the arcus palatinus and the 

 soft palate, forming the groups of the isthmian and palatine glands. 



Similar elements are encountered in the pharyngeal region. They 

 are topographically united into the set of the pharyngeal glands. 



The neighborhood of the terminal of the parotid gland shows in 

 many adult human individuals several small separate glandular 

 masses, opening by independent ducts upon the retroparotid oral 

 mucosa, trending in their general line of development toward the 

 ental surface of the masseter muscle, while the parotid glandular
