tremor

a continuous repetitive twitching of skeletal muscle, usually palpable and visible. The diseases characterized by tremor only, the tremor syndromes, may be caused by degenerative disease of the nervous system, e.g. hypomyelinogenesis, and by many toxins, especially plant ones. Tremor is also a sign in many other diseases of the nervous system.
