fibers by the chorda tympani branch of the facial nerve, which, 

 after running into the lingual of the fifth cranial nerve for a short 

 length, sends its secretory and vasodilator fibers to the sublingual 

 ganglion of Langley to the sublingual glands, whilst the others pass 

 by the sublingual ganglion to the submaxillary gland. 



The submaxillary ganglion lies at the point of departure of

 Otic ganglion. IMNV, Inferior maxillary of the fifth. LN, Lingual nerve.

 chorda tympani also contains vasodilator fibers for the gland and the cervical 

 sympathetic contains vasoconstrictor fibers. 



the chorda tympani from the lingual, but only the nerves going 

 to the sublingual of Langley's gland are connected with it. The 

 sympathetic nerve, as with the parotid, passes up the cervical 

 sympathetic to the superior cervical ganglion, and then to the 

 submaxillary and sublingual glands. 



The afferent fibers of the salivary glands are the taste fibers 

 in the chorda tympani and glosso-pharyngeal, with the branches
