The prime mover, also known as the agonist, is the muscle that actively contracts to produce a specific movement. It is the muscle primarily responsible for the movement, while the synergist muscles assist in the movement and the antagonist muscles oppose the movement. The oppositionist and fixator muscles stabilize the joint or bone during movement.
