Fig. 356. The cranial nerves; nuclei of origin and termination; functional components. 

 (Note: The accompanying figures illustrate the nuclei of origin and nuclei of termination 

 of the various cranial nerves. They are generalized figures and should be regarded only 

 as approximate representations. This must be true, for the position of the respective 

 nuclei within the brain "varies greatly in different orders of vertebrates" [Ranson]. This 

 variation presumably is the result of a developmental principle known as neurohiota.xis. 

 This principle postulates that the dendrites of a neuron together with the cell body move
