How does an antagonist differ from a prime mover (agonist)? How is it the same?
What will be an ideal response
A prime mover is the muscle that causes the desired movement to occur. An antagonist is a muscle that opposes the action of the prime mover in a given movement. If, however, the direction of movement reverses, the former antagonist is now the prime mover and the former prime mover is now the antagonist.
