Fig. 48 Parasagittal section through the medulla oblongata, illustrating the 

 arrangement of fibers of the V, VIII and X roots. Golgi method. X 67. The 

 heavy broken line marks the boundary of the stratum griseum of the auricular 

 lobe, the fine dotted lines the positions of the 'cranial nerve roots. At n.F is 

 indicated the point of entrance of a few fibers from the sensory V root, which 

 immediately divide into descending and ascending branches (.r.V.), the latter 

 terminating in free. arborizations at the rostral end of the auricular lobe. Root 

 fibers of the VIII nerve are seen to bifurcate into ascending and descending 

 branches {r.VIIL), and farther caudad root fibers of two cutaneous roots of the 

 vagus {r.X.s.s.) join the spinal V root (r.V.).

 gittal section. Golgi method. X 100.
