What does muscles work in pairs mean?
Skeletal muscles are arranged as opposing pairs because, although they can shorten themselves by contracting, they have to be stretched back to their former length by other muscles. An example of opposing muscles is in the arm, where the biceps and triceps have opposite actions. As one muscle shortens, the other is stretched. The biceps contracts to bend the arm at the elbow while the triceps stretches. To straighten the elbow joint, the triceps contracts, while the biceps stretches.
