Question

multiple choice question

when muscles stretch and recoil, they recoil to a shorter length. what is this property called?

elasticity
conductivity
contractility
responsiveness

Explanation:

Define the muscle properties

Using the Muscle Characteristics and Muscle Elasticity knowledge points

• Elasticity: The ability of a muscle cell to recoil to a shorter length after being stretched.
• Contractility: The ability of a muscle cell to shorten substantially and pull on connective tissues to generate force.
• Conductivity: The local electrical excitation that sets off a wave of excitation that travels rapidly along the muscle fiber.
• Responsiveness (Excitability): The ability of muscle cells to respond to chemical signals, stretch, and other stimuli with electrical changes across the plasma membrane.

Identify the correct property

Using the Muscle Elasticity knowledge point

• The question asks for the property where muscles stretch and recoil to a shorter length.
• This is the definition of Elasticity.

Answer:

• Elasticity (Correct answer)
• Conductivity
• Contractility
• Responsiveness
