What is Tremor?
{{Other uses}} In biology, a '''tremor''' is when [[antagonist muscles]] move repeatedly without being controlled. There are different forms of tremors. Very often, a tremor is a [[symptom]] for another condition, and not its cause. People with a tremor are not necessarily sick. For example, [[physiological tremor]]s are measurable, but not visible; they occur in all humans. {{biology-stub}} [[Category:Medical signs]] [[Category:Muscular system]]
