PHYSIOLOGY PRACTICUM V: PLATE XV. 

 THE SALIVARY GLANDS OF THE CAT. From Anatomical Technology. 



The skin has been dissected from most of the face and the neck mainly to expose the 

 two larger SALIVARY GLANDS. The PAROTID (Glandula paiotis^\s so named from 

 its proximity to the ear ; most of it has probably been cut off with the ear in the specimen 

 prepared as in PI. II At its cephalic border are seen several ducts converging to form 

 one, the PAROTID DUCT or DUCT OF STENO ; near the corner of the mouth the duct 

 pierces the cheek and opens opposite the largest maxillary tooth ; see Plates XVI and 

 XVII. In man this dnct opens opposite the second molar tooth, the last but one. 



The SUBMAXILLARY GLAND (Gl. submaxillaris} lies caudo-ventrad of the parotid 

 and is separated from it by the JUGULAR VEIN ( V. .jugularis externa} which forms a 

 loop about it. Its DUCT OF WHARTON opens into the floor of the mouth (Fig. 15, Duc- 

 tus Wharton}. Just cephalad of the submaxillary are some LYMPHATIC GLANDS (Gl. 

 lym.} 



Only the parts here enumerated need be considered in this connection. 

 MANDIBLE, the lower jaw. M. Imp., the temporal muscle. M. mstr., the MASSE- 

 TER MUSCLE. ZYGOMA, the zygomatic arch or cheek bone ; see PI. XVI.
