How do muscles work in pairs to move a bone? Explain with the help of an example.

Explanation

**Step-by-Step Solution:**

1. **Understanding Muscle Function**: Muscles work in pairs to facilitate movement. When one muscle contracts (shortens), the other muscle in the pair relaxes (lengthens). This coordinated action allows for the movement of bones.

2. **Muscle Contraction**: When a muscle contracts, it pulls on the bone to which it is attached. For example, when you lift an object, like a bucket, your biceps muscle contracts, pulling the forearm up.

3. **Muscle Relaxation**: While the biceps contract, the opposing muscle, the triceps, relaxes. This relaxation allows the movement to occur smoothly without resistance.
