Movement disorders originate deep within the central nervous system. They are triggered by changes to specific regions of the brain or nervous system controlling movement. People with a movement disorder suffer from a breakdown in the normal flow of neurological messages and this leads to involuntary muscle movement.
A muscle may act ordinarily either under the control of the will or without conscious control. Muscles that can be controlled at will are referred to as voluntary muscles. Those that are not under the control of the will (volition) are called involuntary muscles. Examples of involuntary muscles are the smooth muscles, which are muscles lacking striations when viewed under a microscope. This is why involuntary muscles are sometimes called non-striated or un-striped muscles.
