they enter '.the medulla they branch into two divisions, which 

 end either in the tuberculum acusticum or the nucleus 

 accessorius (N. Ace.), where they form synapses. From

Yestibular Root (Fig. 73). The fibres of this root take 

 origin in dendrites between the cells of the maculse, and have 

 their nerve cell upon their course (Ves. R.). As they enter 

 the medulla they divide into two, forming an ascending
