Repolarization of mucles fibre is not immediately followed by next depolarization. Why?

Explanation

**Step-by-Step Solution:**

1. **Understanding Repolarization and Depolarization:**
- Repolarization refers to the process where the membrane potential of a muscle fiber returns to a more negative value after depolarization. During this phase, the internal environment of the muscle fiber becomes more negative compared to the outside.
- Depolarization, on the other hand, is the process where the membrane potential becomes less negative (more positive) due to an influx of sodium ions (Na+) into the muscle fiber.

2. **Mechanism of Repolarization:**
- During repolarization, potassium ions (K+) flow out of the muscle fiber, which helps restore the negative internal charge. This movement of K+ is crucial for returning the membrane potential to its resting state.
