What is the term for tissues' ability to be stretched to greater length?

• A. Flexibility
• B. Elasticity
• C. Endurance
• D. Extensibility

Answer: (D)

Extensibility is the capacity of tissues to lengthen beyond their resting length when a force is applied. It describes how much a tissue can stretch. Elasticity, by contrast, is the tendency to return to the original length after the stretch. Flexibility refers to how freely a joint can move, which depends on extensibility among other factors, and endurance is about sustaining activity over time. So the tissues’ ability to be stretched to greater length is extensibility.
