Detailed explanation-1: -(1) The muscle in a steady partially contracted state caused by the successive flow of nerve impulses. (2) The amount of tension or resistance to movement in a muscle. Muscle tonus helps in maintaining body posture.
Detailed explanation-2: -Muscle tone is the state of a partial passive contraction that occurs in the muscle when the muscle is at rest. The resistance of muscle occurs in the presence of the passive stretch that occurs in the resting state. It is important that muscle tone occurs during resting state so that the health is maintained.
Detailed explanation-3: -In isotonic contraction, the tension in the muscle remains constant despite a change in muscle length. This occurs when a muscle’s force of contraction matches the total load on the muscle.
