While their size and shape vary with location in the nervous system, most neurones contain the same parts: a cell body; a number of highly-branched outgrowths of the cell body called dendrites; a single, long nerve fibre (or axon) extending from the cell body; and branches at the end of the nerve fibre (axon terminals).
My doctor said that usually happens when blood pressure is high and you get that strange head sensation. But as I was reading some documents on net, I found out that it could also be some sort of a panic attack. You could try next time it happens to relax, try thinking on some peaceful place, and just calm down.
So what triggered the leap from hearing loss to incapacitating dizziness in Miller's case? The etiology is unknown, Miller says, pointing to the possibility of a virus or inner-ear inflammation. Tumors are another cause, says Nevin, along with specific conditions such as Meniere's disease or benign paroxysmal positional vertigo, the latter of which is the most common. In BPPV, which is diagnosed with a simple clinical test, particles in the inner ear dislodge and cause the spinning sensation when one rolls over in bed or bends. I can't remove the particles, but I can help them go back in place, says Nevin.
