What are the 3 main characteristics of muscle tissue?

• A. Contractability, Extensibility and Elasticity
• B. Strength, Endurance, and Tone
• C. Rigidity, Elasticity and Flexibility
• D. Contracability, Extensibility and Elasticity

Answer: (D)

Muscle tissue has three fundamental properties that describe how it functions: contractility, extensibility and elasticity. Contractility is the ability of muscle fibers to shorten actively in response to stimulation, producing movement and force. Extensibility means muscle can be stretched beyond its resting length without damage, allowing a range of motion. Elasticity is the ability to return to the original length after being stretched or contracted, thanks to the tissue’s elastic components.

The standard term for the first property is contractility, and while some spelling variations appear, the concept is the same. The other options mix general performance traits or different ideas that aren’t about the intrinsic properties of muscle tissue. So the three main characteristics are contractility, extensibility, and elasticity.
