ANATOMY

Detailed explanation-1: -Agonists are also referred to as prime movers since they are the muscles that are primarily responsible for generating the movement. These muscles act in opposition to the movement generated by the agonists and are responsible for returning a limb to its initial position.

Detailed explanation-2: -We describe the main muscle that does an action as the agonist. It is sometimes also called the “prime mover”. Many actions in the body do have one muscle that is responsible for more of the work in that action than any other muscle. For example, the agonist, or prime mover, for hip flexion would be the iliopsoas.

Detailed explanation-3: -The muscle primarily responsible for a movement is called the prime mover, and muscles that assist in this action are called synergists. A synergist that makes the insertion site more stable is called a fixator. Meanwhile, a muscle with the opposite action of the prime mover is called an antagonist.

Detailed explanation-4: -agonist: These muscles are typically associates with the movement itself, and are sometimes referred to as prime movers. They contract while another muscle relaxes. synergist: This type of muscle acts around a movable joint to produce motion similar to or in concert with agonist muscles.

Detailed explanation-5: -Agonist: The agonist in a movement is the muscle(s) that provides the major force to complete the movement. Because of this agonists are known as the ‘prime movers’. In the bicep curl which produces flexion at the elbow, the biceps muscle is the agonist, as seen in the image below.
