Detailed explanation-1: -1. 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.
Detailed explanation-2: -Although a number of muscles may be involved in an action, the principal muscle involved is called the prime mover, or agonist. During forearm flexion, for example lifting a cup, a muscle called the biceps brachii is the prime mover.
Detailed explanation-3: -Synergists. Synergists help muscle movement by either adding a little extra force to the same movement or reducing undesirable or unnecessary movements that might occur as the prime mover contacts.
