C)The maximum contraction strength that a muscle is capable of
D)The tension in a muscle that is only due to the passive resistance of elastic structures
E)The average length of the muscle fibers in a given motor unit

Question

Quizplus · Accepted Answer

Muscle tone refers to the resistance of a muscle to continuous passive stretch. It is the result of the involuntary low-level contraction of muscle fibers, even when the muscle is at rest.

Answer: D
 Muscle tone is the tension in a muscle that is only due to the passive resistance of elastic structures in the muscle, such as tendons and connective tissue. This tension is present even when the muscle is not actively contracting.

Therefore, both options A and D are correct. However, option A is a more commonly used and widely accepted definition.
