Which term is defined as the resistance of a muscle to active or passive stretch, reflecting tone?

• A. Tone
• B. Tone Quality
• C. Muscle Tone
• D. Motor Drive

Answer: (C)

Muscle tone is the ongoing tension that a muscle holds, which sets how much it resists being stretched, whether you actively move it or someone else moves it passively. This resistance comes from a combination of neural input to the muscle (the baseline activity of motor neurons and the way spindle sensitivity is modulated) and the muscle’s inherent elastic properties. Because the statement describes this resistance as a reflection of tone, the precise term is Muscle Tone. The other options don’t fit as well: Tone alone is too vague, Tone Quality is a term used in contexts like voice or music rather than describing muscle properties, and Motor Drive refers to neural commands that influence tone rather than the actual resistance to stretch itself.
