Quizplus · Accepted Answer

Motion sickness often occurs when there is a discrepancy between the visual and vestibular (inner ear balance) systems. This conflict between what one sees and what one's balance system senses can lead to symptoms of motion sickness.  The vestibular system tells us how our body is oriented in the world with respect to gravity. Most people who lose their vestibular sense compensate by using their visual system. Motion sickness occurs when signals from the vestibular system and the visual system conflict. When someone is motion sick, the visual system signals a stationary object while the vestibular system signals movement.
