Distribution 



Preganglionic fibers in chorda 

 tympani; postganglionic fi- 

 bers from sub-maxillary gan- 

 glion to submax. and sub- 

 lingual glands. 



Stapedius, posterior belly of 

 digastric, stylohyoid muscle. 



Sup. petrosal, chorda tympani, 

 tympanic plexus. 



Chorda tympani and lingual 

 nerve to taste buds on ante- 

 rior two-thirds of tongue. 



Semicircular canals, sacculus, 

 utriculus. 



Organ of Corti of Cochlea. 



Preganglionic fibers in tymp. 

 and sup. petrosal nerve; 

 postganglionic from otic gan- 

 glion to parotid gland. 



Stylopharyngeus muscles. 

 (Unstriped pharyng.) 



Sensory fibers to pharynx, 

 posterior one-third of tongue. 

 (Lingualis IX.) 



Tastebuds of post, one-third of 

 tongue. 



Tactile corpuscles of posterior 

 one-third of tongue. 



Preganglionic sympathetic fi- 

 bers to pharynx, stomach, 

 heart, lungs, trachea. 



Superior and inferior laryngeal 

 and pharyngeal nerves to 

 striated muscles of pharynx 

 and larynx. 



Nerves from viscera, larynx, 

 pharynx, lungs, heart, and 

 sympathetic connections. 



Internal laryngeal nerve. 



Ramus auricularis vagi. (Be- 

 hind ear.)
