Fig. 232. Diagram showing the main parts of the autonomic nervous system to be used along 

 with Fig. 233. For the sake of clarity several of the preganglionic fibers of the sympathetic 

 autonomies are omitted, but the position 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.
