Solution
The correct statement is: "muscles move joints by pulling".
Here's why:
-
Muscles are attached to bones by tendons. When a muscle contracts, it shortens, pulling on the bone it's attached to and causing it to move.
-
Muscles can only pull. They cannot push. This is because when a muscle contracts, it pulls the two ends closer together. When it relaxes, it simply stops pulling and allows the bone to return to its original position.
-
Therefore, muscles move joints by pulling, not by pushing.
-
The statement "muscles are not involved in the movement of joints" is incorrect. Without muscles, our joints would not be able to move.
