title: [Traverse connectivity of innervation in the vestibular sensory epithelium].
abstract: OBJECTIVE
  To further understand the traverse connections of nerve components in the vestibular sensory epithelium.
  
  
  METHODS
  The nerve innervations in the vestibular sensory epithelia and infraepithelia of ten healthy guinea pigs (16 ears) were observed by transmission electron microscopy.
  
  
  RESULTS
  Type I sensory cells were intricately connected with type II cells. Afferent and efferent fibers as well as their endings had also complicated connections with nerve trunks and branches. The traverse connections appeared among nerve components in the vestibular sensory epithelium were extremely complicated, forming multilevel connections. They stemmed from and end in the crista ampullaris and the maculae.
  
  
  CONCLUSIONS
  These complicated and multilevel connections are the basis of nerve activity in the vestibular apparatus.
