sensory neurones. The cell-bodies of such neurones, as has been 

 stated, are found in the spinal and homologous cranial ganglia. 

 Of the two branches arising from the single process possessed by 

 each peripheral sensory neurone, the one going to the periphery is 

 regarded as the dendrite and forms the axis-cylinder of a medullated 

 nerve-fiber, such nerve-fibers constituting the sensory nerves of the 



Nucleus and 

 nucleolus.

 fore be diagramed as in figure 134. The statement was made 

 above that the essential portion of a sensory nerve-ending is a telo- 

 dendrion (end-brush) or several telodendria of the dendrite of a 

 peripheral sensory neurone. The character of a sensory nerve-
