The inner ear includes:

  • oval window – connects the middle ear with the inner ear
  • semicircular ducts – filled with fluid; attached to cochlea and nerves; send information on balance and head position to the brain
  • cochlea – spiral-shaped organ of hearing; transforms sound into signals that get sent to the brain
  • auditory tube – drains fluid from the middle ear into the throat behind the nose
