The vestibule is an approximately 4 mm central chamber of the bony labyrinth. It is dominated by depressions housing the:

  1. utricle (elliptical recess)
  2. saccule (spherical recess)
  3. basal end of the cochlear duct (cochlear recess)

The cribrose areas have perforations through which the nerve bundles gain access to the inner ear. The endolymphatic duct is housed within the bony vestibular aqueduct and originates at the posteroinferior aspect of the vestibule.
