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)

Besides they need to be balanced
For Ex: Triceps w/ Biceps

What structure work in antagonistic pairs to move bone?
Skeletal Muscles
Why must skeletal muscles work in pairs to move a bone?
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.

Skeletal muscles
How does the skeletal and muscular systems work together to raise and lower the forearm?
The biceps and triceps muscles work synergistically; the biceps muscles contracting concentrically and the triceps muscles contracting eccentrically when the forearm lifts, and it's the exact reverse when the forearm lowers.
What are antagonist pairs of muscles?
pairs of muscles that work together
What are antagonist pairs are muscles?
pairs of muscles that work together
At least how many muscles work together to move one bone?

How can muscles work in pairs?
ussually, one muscle in the pair bends part of the body.the other muscle straightens part of the body.
What body parts work in pairs to pull your bones in different directions?
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.
Why might some muscles fail to work properly if a bone is broken?
Because the muscles work by pulling on the bone. If the bone is broken, the force may not be transmitted to where it is needed.
What is the difference between a muscle and a tendon?
Muscles,tendons,and bones are related because tendons connect muscle to bone and ligaments connect bone to bone.Tendons connect your muscles to your skeleton so that your muscles will make the bones move to were you need it to go.
