Fig. 220. Diagram showing the main parts of the autonomic nervous system. For the sake of 

 clarity several of the preganglionic fibers of the sympathetic autonomies are omitted, but the posi- 

 tion of their egress from the cord is indicated in the side notes. The diagram shows clearly the 

 distribution of the bulbosacral autonomic system by way of the vagus and the first, second and 

 third sacral nerves.
