forearm and upper arm muscles.
Agonist & AntagonistsAgonist is the muscle responsible for the primary movement ( muscle that contracts)Antagonist is the opposite muscle that must relax to allow the agonist to move a joint.
Triceps :)
your heart is the muscle that you cant move yourself
the poopets and the troopets
the muscles and the bone work together and attached
antagonistic muscles
They are the muscles. Muscles contract in pairs to move the parts across the joint. One muscle contract with more power. The opposite muscle contracts with less power and get stretched over to allow the first muscle to act.
Skeletal muscles work in pairs to move a bone so that the muscles can function properly. Muscles can only pull, therefore bones need two muscles to make it move. To put a finger up one muscle might pull, the other will put to put back down. With two, the movement will be smooth, otherwise it will be "jerky" and uncontrolled.
Human Muscle
AnswerThough not all muscles work in pairs, the general principle is that one muscle moves a bone one way, and the other muscle moves it the opposite way. Why? Because muscles can only pull, not push.For example, when you bend your arm, the biceps muscle pulls. When you want to straighten it, the biceps muscle cannot push it back. Instead, the triceps muscle that's on the back of the arm pulls in the other direction.
When one muscle of a pair contracts, the other muscle of the pair relaxes to allow movement of the body part.
an organ is a system that helps your bodily functions. a muscle helps you work and move.
