Fig. 16.15. Diagram of autonomic nerves that carry impulses to various 

 organs. Figures of the organs are repeated on each side in order to avoid over- 

 lapping of the pathways. The diagram emphasizes the fact that each organ re- 

 ceives a double supply of autonomic nerves, the parasympathetic and the sym- 

 pathetic nerves carrying antagonistic impulses that increase or decrease activity. 

 The Arabic numerals on the cord stand for spinal nerves, the Roman numerals 

 for cranial nerves. (Courtesy, Turner: General Endocrinology. Philadelphia, W.
