Question

multiple choice question

what is the characteristic that allows muscles to pull on bones and organs to create movement called?

conductivity
contractility
excitability
metabolism

Explanation:

Analyze the question prompt

The question asks for the specific characteristic of muscle tissue that enables it to pull on bones and organs to generate movement.

Define the options

• Conductivity: The ability of a cell to propagate an electrical signal (action potential) along its membrane.
• Contractility: The ability of muscle cells to shorten forcefully, which pulls on attachment points (like bones or connective tissues) to create movement.
• Excitability: The ability of a cell to receive and respond to a stimulus (such as a neurotransmitter or electrical signal).
• Metabolism: The sum of all chemical reactions that occur within a living organism to maintain life.

Match the characteristic to the function

The action of "pulling on bones and organs to create movement" directly requires the physical shortening and tension generation of the muscle fibers. This physical shortening is the definition of contractility.

Answer:

• Conductivity
• Contractility (Correct answer)
• Excitability
• Metabolism
