Question

Quizplus · Accepted Answer

The prime mover, also known as the agonist, is the muscle that is primarily responsible for generating movement during a particular action or exercise. It contracts concentrically to initiate and carry out the movement, while the other muscles work as synergists to help stabilize and contribute to the motion. The antagonist muscle group works in opposition to the prime mover, helping to control the speed and direction of the movement. The insertion is the attachment point of the muscle to the bone that moves, often in conjunction with the origin, which is the attachment point of the muscle to the bone that stays still.
