Energy is the internal, inherent power, the product of activity, that which is aroused by an impulse. Nerve-vibration carries thoughts, commands, orders, known as impulses when in transit over the nervous system. Thoughts gather force, receive impetus, while being transmitted, the amount depending upon the quantity of nerve vibration. Momentum is the force of motion acquired by the movement of thoughts, the impetus received from nerve-vibration. Tone is the normal activity, strength and excitability of the various organs and functions as observed in health.
Tone is a response of tonicity.
Tonicity is the normal elasticity of the filamentary or threadllike structures of the body, the nervous system. To innervate is to supply with nerve-force. To enervate is to deprive of nerve-force. An impulse is a communicated thought. Impulses are conveyed over the nervous system by means of vibration.
