THE NEKVE CELL

parallel either to the nuclear membrane or to the surface of the 

 cell. These cells are most abundant in the motor nuclei of the 

 spinal cord and brain. 



3. Gryochrome nerve cells, whose stainable granules present a 

 tendency to agglutinate into clumps or threads. These cells are 

 less numerous, but may be found in the corpus striatum. 



4. Arkyostichochrome nerve cells, whose stainable granules, 

 while presenting a delicate network, show at the same time a dis- 



Fio. 104. MOTOR NERVE CELL FROM THE VENTRAL HORN OF THE SPINAL CORD OF A 



RABBIT. 



Of the three lower processes, the middle one represents the neuraxis. All the other 

 processes are dendrites. The margins of the cell and of the masses of stainable sub- 

 stance appear too sharp in the reproduction. At the angle of division of the large 

 dendrite at the left superior angle of the cell is shown one of the " wedges of division." 

 This is classed as a stichochrome nerve cell in the apyknomorphous condition. Highly 

 magnified. (After Nissl.)
