Question 4

Dancers will use a technique called "spotting" when they perform spins of the body. By holding their head and eyes on a fixed point in front of them as their body spins they reduce the amount of head spinning and this prevents dizziness. Which of the following is the most likely explanation for why this works?

Accepted Answer

A)  This will help to reduce the lateral flection of the head and will prevent hyper polarization or depolarization of the hair cells in the macula. 
B)  When the eyes send a static vision of stability to the brain, it is tricked into believing the body is still and therefore dizziness will not occur. 
C)  Reducing the inertia of head spin will reduce the flow of endolymph that deflects the hair cells of the crista ampullaris. 
D)  This helps keep the motions detected by the eyes congruent (aligned) with the motions sensed by the vestibular apparatus.
