Answer:
There is a skeletal muscle on the outer side of the eye ball called Lateral Rectus. If this muscle contracts (shortens) the eye ball would rotate outwards.
Suppose that we are looking at what is in front of us.
1. If our right Lateral Rectus muscle shortens we would be actually seeing what is there to our right.
2. If the right Lateral Rectus muscle contracts Isometrically then there would be no change in the length of the muscle and therefore we would still be seeing what is in front of us.
However, the Isometric contraction of the muscle would give us a feeling that we are seeing what is to our right.
If the right Lateral Pterygoid muscle contracts and relaxes repeatedly then we would get a feeling that what is there in front of us is moving to our right.
Thus, vertigo is caused by Isometric oscillation of the skeletal muscle called Lateral Rectus.
