- - - - vibrations are transmitted along the length of Scala vestibuli
      - most pressure is transmitted into cochlear duct
      - nerve impulses generated pass to the brain
      - in the cochlear portion of the vestibulocochlear nerve
      - fluid wave is finally expanded into the middle ear
      - By vibration of the membrane of round window
    - - Direct the along the auditory canal
      - causing tympanic membrane to vibrate
      - collect and concentrate the wave
    - - to auditory nuclei in the medulla
      - they synapse before conducted to auditory area in temporal lobe
      - vestibulocochlear nerve transmits impulses
- - - - convergence (movement of eyeballs)
        
        light rays from nearby objects enters the two eyes at different angles
      - changing power of lens
        
        the amount of adjustment depend on distance of object from the eye
      - constriction of pupil
        
        assist accommodation by reducing beam of light entering the eye
    - - it allows to perceive depth ad relationships between object
      - each eye sees slightly different spatial information and transmits these differences to brain
      - then brain uses discrepancies between the eyes to judge distance and depth
    - - the bending refraction makes it possible for us to have lenses
      - magnifying glasses, prisms and rainbows even if the eyes depend in bending and light
      - it passes from one transparent substance into another
