A TEXTBOOK OF PHYSIOLOGY 



atropine abolishes both effects. This is because nicotine paraly/.rs 

 only the preganglionic, atropine paralyzes the postganglionic nerve 

 endings also. 



The cranial autonomic fibres may be summarized as follows : 

 Nerve. Cell-Station. 



Third nerve 



Ciliary ganglion 



Function. 



Motor to sphincter pupilhe 

 and ciliary muscles. 



Seventh nerve 



(1) Submaxillary 



(2) Ganglion inhilus 

 of submaxillary - 

 gland 



Otic ganglion 



? Spheno. palatine 



(1) Vaso-dilator to tongue; se- 

 cretory and vaso-dilator to 

 sublingual gland. 



(2) Secretory and vaso-dilator 

 to submaxillary. 



Secretory and vaso-dilator to 

 parotid, and ? vaso-dilator 

 to back of tongue. 



? Secretory and vaso-dilator to 

 mucous membrtme of nose, 

 soft palate, and pharynx. 



Vagus 



Terminal ganglia 

 in organs 



Motor to oesophagus, bron-
