Strictly speaking, it's not. It's just that, having moved it using one muscle, you might want to be able to move it back to where it was before, in which case you'll probably need a muscle that pulls the opposite direction.

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 causes a joint to move?
Joints don't have the ability to move. Joints are where two or more bones meet. One end of muscle attaches to the bone and the other end of the muscle stretches cross the joint and attaches to the bone on the other side of the joint. Muscles work in pairs, so that when one muscle contracts (the only movement that muscle can make), the other of the pair relaxes which causes movement at the joint when the bone is pulled by the muscle.
