 spinal axis. 



The connections between these parts are as follows: i. The visceral

chain. 2. The gray rami consisting of bundles of fibers, usually non-medul- 

 lated, which pass from the chain ganglia back into the spinal or cranial nerves, 

 the fibers of which they accompany to the periphery. 3. From the ganglionic 

 chain the rami e/erentes pass into the collateral ganglia, and from these again 

 other branches pass off into the organs, to end in terminal ganglia or more 

 often in the tissue.
