Accepted Answer

The muscle that contracts to produce a particular action is known as the agonist or prime mover. It is responsible for generating the most force during a particular movement. The antagonist is the muscle that opposes the action of the agonist and helps to control the movement. The origin refers to the point of attachment of the muscle to the bone that is most stationary during the movement, while the insertion refers to the point of attachment of the muscle to the bone that is most movable during the movement.
