THE NERVOUS SYSTEM 



C. By Way of the Dorsal Spinocerebellar Tract: 



Neuron I. The first neuron of this chain is similar to the primary neuron 

 in the. three preceding paths. The impulses, however, travel over those col- 

 lateral and terminal branches of the dorsal root fibers which ramify about the 

 cells of the nucleus dorsalis.

Neuron II. From cells in the nucleus dorsalis fibers run to the dorsal spino- 

 cerebellar tract of the same side and through the restiform body to the cortex 

 of both the rostral and the caudal portions of the vermis (Fig. 235, red).
