Which term describes the ability of a muscle to be stretched?

• A. Excitability
• B. Contractility
• C. Extensibility
• D. Elasticity

Answer: (C)

Extensibility describes how much a muscle can be stretched beyond its resting length. This property lets muscles lengthen when you move through a range of motion or hold passive stretches. In contrast, elasticity is about snapping back to the original length after stretching. Since the question asks for the ability to be stretched, extensibility is the best description.
