side of the tongue, and, crossing Wharton's duct externally, 

 is continued to the tip of the tongue 



Branches : 



Communicating: with inferior dental at commencement ; with 

 facial through chorda tympani ; branches are sent also to 

 submaxillary ganglion and the hypoglossal nerve. 



Distributary: to mucous membrane of sides and tip of tongue, 

 the gums and sublingual gland, the terminal branches supply- 

 ing anterior f of mucous membrane of dorsum. 



The SUBMAXILLARY GANGLION lies between the hyoglossus 

 muscle and the deep part of the submaxillary gland. 



Roots : 



Motor and sensory : the connecting branch from the lingual 

 supplies sensory and motor from the facial, through the chorda 

 tj'mpani. 



Sympathetic : from plexus round facial artery. 



Branches : 



Five or six small twigs supply the submaxillary gland, the 

 mucous membrane, and Wharton's duct. 



The OTIC GANGLION (Arnold's) lies on the inner surface of 

 the inferior maxillary nerve, close to the foramen ovale, and 

 is connected with the commencement of the nerve to the 

 internal pterygoid muscle. 



Roots : 



Motor and sensory: from the inferior maxillary, by the 

 branch to the internal pterygoid. 



Sympathetic : from plexus on middle meningeal artery, which 

 lies just behind it. 



The small superficial petrosal nerve passes into the posterior 

 part of the ganglion connecting it with the facial and glosso- 

 pharyngeal nerves. 



Branches : 



Communicating: to auriculo- temporal, and to chorda tym 

 pani. 



Muscular: to the tensor tympani, and tensor palati.
