Well you have two muscles in your arm: the bicep and tricep. In order to make the arm move the two muscles must flex while the other extends and vice versa. So the bicep flexes and the tricep extends (the arm is bent). The bicep extends and the tricep flexes (the arm is straight)

What muscle pair helps you move your arm?
Biceps/triceps.
What happens when you move your arms but the muscle doesn't move?
You cannot move your arm without using the muscle. Unless you use your other arm to move it. You may not be able to see the muscle move, but it must contract in order for the arm to move.
What would be the antagonist to the muscle that flexes the arm would be a muscle that?
Looks like you are looking for the antagonistic pair. The muscular group that flexes the arm would be the antagonistic pair of tricep brachi and the brachialis.
In a muscle pair the muscles work in opposition to each other?
Yes, muscle pairs work in opposition to one another. The lengthening of the biceps, for instance, shortens the triceps. That helps move your arm.
Is a upper arm a involuntary muscle or a voluntary muscle?
voluntary, a typical person can move it at will.
What is the function of arm bones?
They are a part of your body and your bones. And your arm bones also lead your arm and muscle to move.
Describe how the muscles in your upper arm work together to bend and straighten your lower arm?
While one muscle contracts, the other muscle in the pair returns to its original length
IF one muscle in a pair relaxes what does the other muscle do?
It contracts. Say if you have your arm bent and you extend it, the tricep is contracting, and the biscep is relaxing.
How do muscles work pairs to move the body?
When one muscle of a pair contracts, the other muscle of the pair relaxes to allow movement of the body part.
How do muscles work in pairs to move the body?
When one muscle of a pair contracts, the other muscle of the pair relaxes to allow movement of the body part.
