In lesson 2 an example was given to show how your muscles contract to move a joint.In your own words describe that example with material they used.
Answer (1)
When muscles contract to move a joint, it’s like pulling on a rope. For example, in the lesson, they might have used a rubber band to show how muscles tighten. When the rubber band is stretched and then released, it pulls back—just like how muscles shorten and pull on bones to move a joint, like bending your elbow or knee.
