The smaller sympathetic ganglia associated with the rami of 

 the glossopharyngeal nerve in the posterior portion of the tongue 

 arise from cells which advance into the tongue along the glosso- 

 pharj^ngeal fibers. 



The cells which give rise to sympathetic neurones are derived 

 both from the cerebrospinal ganglia and the neural tube. Not 

 all of these cells actually migrate as such from the cerebrospinal 

 nervous system. Many of them arise by the mitotic division of 

 migrant cells along the paths of migration and in the primordia 

 of the sympathetic nervous system.
