When the surface electrons of a material are disturbed, an imbalance of negative and positive charges arises between the. inter-acting surfaces, and results in the phenomenon known as. static electricity. A deficiency or surplus of a single electron.
Vertigo is usually due to a disturbance in the vestibular system. The vestibular system is one of three sensory systems subserving spatial orientation and posture; the other two are the visual system (retina to occipital cortex) and the. somatosensory system that conveys peripheral information from skin, joint, and muscle receptors.
Benign positional vertigo. Benign positional vertigo is the most common type of vertigo. Vertigo is the feeling that you are spinning or that everything is spinning around you. It may occur when you move your head in a certain position. Benign positional vertigo is also called benign paroxysmal positional vertigo (BPPV). It is caused by a problem in the inner ear. The inner ear has fluid-filled tubes called semicircular canals. When you move, the fluid moves inside these tubes. The canals are very sensitive to any movement of the fluid.
