Verified step by step guidance

Understand the concept of muscle tone: Muscle tone refers to the continuous and passive partial contraction of the muscles, or the muscle's resistance to passive stretch during resting state.

Recognize that muscle tone is important for maintaining posture and ensuring muscles are ready to respond to stimuli.

Differentiate muscle tone from other terms: A 'twitch' is a single, quick contraction of a muscle fiber. 'Tetanus' is a sustained muscle contraction. 'Stimulation' refers to the activation of muscle fibers by a nerve impulse. 'Summation' involves the additive effect of multiple stimuli on muscle contraction.

Identify that muscle tone is not a complete contraction but a state of readiness and health for the muscle, which is maintained by the nervous system.

Conclude that the term describing the continued mild or partial contraction of a muscle that keeps it healthy and ready to respond is 'muscle tone'.
