The knee joint is an example of a body joint that opens and closes as it flexes and extends during movement.
The muscle that closes the joint during movement is called the "agonist" or "prime mover." It contracts to create the desired action, while the opposing muscle, known as the "antagonist," relaxes to allow the movement to occur.
Muscles that brings the two (or more) bones that form it closer are called flexors.
