SFS Characteristics of Muscle Tissue

Front

What is Extensibility in muscle tissue?

Back

Extensibility is the ability of muscle tissue to be stretched without being damaged. It allows muscles to lengthen when force is applied.

Front

What is Elasticity in muscle tissue?

Back

Elasticity is the ability of muscle tissue to return to its original shape after being stretched or contracted.

Front

What is Contractility in muscle tissue?

Back

Contractility is the ability of muscle tissue to shorten and generate force when stimulated.

Front

What is Excitability in muscle tissue?

Back

Excitability is the ability of muscle tissue to respond to stimuli, such as nerve impulses, and generate an action potential.

Front

Example of Extensibility: A dancer does a full leg extension without tearing her muscles. What characteristic does this demonstrate?

Back

This demonstrates the characteristic of Extensibility.

Front

Example of Elasticity: After doing a leg extension, the gymnast’s muscles return to their original size. What characteristic does this demonstrate?

Back

This demonstrates the characteristic of Elasticity.

Front

Example of Contractility: Your brain sends a message to your hamstrings to contract. What characteristic does this demonstrate?

Back

This demonstrates the characteristic of Contractility.

Front

Example of Excitability: Your hamstrings respond to a message from your brain. What characteristic does this demonstrate?

Back

This demonstrates the characteristic of Excitability.

Front

How does Extensibility benefit muscle function?

Back

Extensibility allows muscles to stretch and accommodate movements without injury, enabling a greater range of motion.

Front

How does Elasticity benefit muscle function?

Back

Elasticity allows muscles to return to their original shape after stretching, which is essential for repeated movements.
