が弛緩しているときには、活動電位は現れないが、少し
でも活動すると、それに対応して活動電位が現れる。(Disclosure of the Invention) Muscle contraction and tension i are caused by the excitatory activity of the motor nervous system controlling the muscles. When a muscle receives stimulation from the nervous system, an action potential appears and the muscle contracts. In other words, when a muscle is relaxed, no action potential appears, but when the muscle is activated even slightly, an action potential appears.
