Children usually feel sick in the stomach when travelling in a car, airplane, boat or train. This sickness is known as motion sickness. This sickness is caused by reception of wrong signals by eyes, muscles, skin receptors, and inner ears. While travelling, different body parts send different signals to the brain. Eyes see things around and it sends signals about the direction of movement while in motion. The joint sensory receptors and muscles send signals about the movement of the muscles and the position in which the body is. The skin receptors send signals about the parts of the body which are in contact with the ground. The inner ears have a fluid in the semicircular canals. This fluid senses motion and the direction of motion like forward, backward, up, down, circular, or to and fro. When the brain gets timely reports from the various body parts, it tries to find a relation between all the signals and then sketches a picture about the body
