And, vice versa. When the triceps contracts, pulling the lower arm back down to its starting position, the biceps relaxes. Most, but not all, of the skeletal muscles in your body work in these agonist-antagonist pairs. If the agonist flexes a muscle, then its antagonist extends the muscle.
This is called antagonistic muscle action. The working muscle is called the prime mover or agonist. (it s in agony!) The relaxing muscle is the antagonist. The other main pair of muscle that work together are the quadriceps and hamstrings.The prime mover is helped by other muscles called synergists.These contract at the same time as the prime mover. They hold the body in position so that the prime mover can work smoothly.it s in agony!) The relaxing muscle is the antagonist.
