ganglion). Many, if not all the fibres, are connected with the cells of 

 this ganglion. 



After traversing the spiral lamina they emerge in bundles, and the 

 fibres then, having lost their medullary sheath, pass into the epithe- 

 lium of the inner hair-cell region. Here some of them are directly 

 continuous with the inner hair-cells, whilst others pass in the form 

 of delicate fibrils across the tunnel of Corti, to become applied 

 to the outer hair-cells (fig. 321); but there does not appear to be a 

 direct continuity in this case between the nerve-fibrils and the cell- 

 substance.
