AXATOMY AND PHYSIOLOGY OF THE SPINAL COED. 401 







Fig. 212 (VAN DER KOLK). Transverse section through the anterior horn and entrance 

 of a nerve root. A A, Medullary matter; B B, grey matter of the anterior horn with its 

 cells and nerve fibres ; a 6, two motor nerve-roots; c c c, multipolar cells into which the 

 fibres of the nerve-roots pass; d e, another group of cells connected partly with the pre- 

 ceding, partly with one another, and which receive numerous filaments from the marginal 

 fibres surrounding the grey matter; fg h i, grey radii; their fibres either pass at once 

 into cells, as at /, or penetrate to the remote cells, as at A, or they form marginal fibres, as 

 at t, all of which seem to be lost in remote cells, and decussate with the nerve root a, without 

 passing into it.
