7. Prolongation of the sympathetic nerve, accompanying the; vertebral .artery. 



It proceeds from the superior ganglion, which is placed, between the glosso- 

 pharyngeal nerve and the par vagum. Another branch passes down the 

 neck with the carotid artery, and although it appears to be principally for 

 supplying the bloodvessels, it corresponds with the prolongation on the 

 anterior part of the neck in other classes.
