The cells of the sympathetic, unlike those of the bulbar and 

 spinal ganglia, are for the most part multipolar and smaller and 

 almost uniformly round (Fig. 195). Stohr distinguishes three

types of ganglion cells (Fig. 196) to which no distinctive function 

 can at present be attributed. 



The nerve-fibres are of two kinds. The first are ordinary 

 medullated nerve-fibres, which are found in the white ranii 

 communicantes ; these, which connect the spinal cord and the 

 sympathetic, originate in the cells of the lateral horn of the cord, 

 and conduct to the ganglia of the lateral chain.
