Vertigo. Motion sickness. Motion sickness occurs when the brain receives conflicting information from the eyes, skin pressure receptors, muscle and joint receptors, and inner ears. This can occur when you ride in a boat, airplane, car, or even on an amusement park ride. Nausea and vomiting are common with motion sickness. Benign positional vertigo. Calcium deposits in the back part of the inner ear, also known as the semicircular canals, cause benign positional vertigo. It usually lasts less than one minute.
In vestibular neuritis, dizziness is attributed to a viral infection of the vestibular nerve (see figure 1). The vestibular nerve carries information from the inner ear about head movement. When one of the two vestibular nerves is infected, there is an imbalance between the two sides, and vertigo appears.abyrinthitis is also always attributed to an infection. Figure 1: Cutaway of the inner ear. Movement of the head is detected by the semicircular canals, and transmitted to the brain via the vestibular nerve. Vestibular neuritis may affect the nerve itself or the vestibular ganglion (Scarpa's ganglion).
