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.
Quick Answer. Involuntary activities are controlled by the autonomous nervous system, whose main component is a part of the brain stem called the medulla oblongata. This system, as a subset of the peripheral nervous system, functions outside the brain and spinal cord and is composed of the sympathetic and parasympathetic nervous systems. The medulla oblongata directly controls heartbeat, blood pressure, breathing and digestion. The sympathetic nervous system controls the body's fight-or-flight response, which quickly increases blood flow and breathing rate in response to danger or excitement. The parasympathetic nervous system does the opposite; it reverses the changes done by the sympathetic nervous system in order to calm the body, although its response is slower and occurs over the course of a few minutes.
