suspended from the lingual nerve by two connecting branches, 

 posterior and anterior, which stand apart from each other. The 

 posterior connecting branch, sometimes broken up into two or three 

 twigs, conveys to the ganglion sensory fibres from the chorda t^inpani 

 (sensory portion of the facial) and lingual nerves, the latter being 

 a branch of the inferior maxillary division of the fifth cranial nerve. 

 The anterior connecting branch represents fibres passing front the 

 ganglion to the lingual nerve. 



The posterior branch consists of fibres which are derived from the 

 chorda tympani of the facial, and from the lingual nerve. This 

 posterior branch may exist as two twigs. The anterior branch

may be regarded as an offset from the ganglion to join the lingual. 

 The sympathetic root of the ganglion is derived from the plexus on 

 the cervical portion of the facial artery.

The submaxillary ganglion has three roots— secretor>% sensory 

 and sympathetic. The secretory root comes from the chorda 

 tympam ner\'e; the sensory root from the Ungual nerv^e; and the 

 sympathetic root from the plexus on the cervical portion of the 

 facial artery. The secretory and sensory roots represent the pos- 

 terior connecting branch of the ganglion. 



Branches.— These proceed from the lower and anterior parts of 

 the ganghon, and are as follows: (i) glandular to the submaxiUary
