**Action Potential Graph Explanation**

This graph illustrates the changes in membrane potential (mV) of a neuron over time (msec) during an action potential.

**Key Phases and Events:**

1. **Neuron Reaches Threshold:**
- At the beginning of the graph, the membrane potential is at rest. As it approaches the threshold, the potential slightly depolarizes, setting the stage for an action potential.

2. **Sodium Enters the Neuron:**
- Once the threshold is crossed, there is a rapid depolarization indicated by a steep rise in the curve. This occurs as sodium (Na+) ions enter the neuron through voltage-gated sodium channels, making the inside of the neuron more positive.

3. **Potassium Exits the Neuron:**
- Following the peak of the action potential, the curve begins to fall during repolarization. This is caused by potassium (K+) ions exiting the neuron as sodium channels close and potassium channels open, restoring the negative membrane potential.

4. **Na+/K+ Pump Resets Neuron:**
- After hyperpolarization, where the membrane potential temporarily becomes more negative than the resting potential, the Na+/K+ pump works to restore the neuron to its resting state by actively transporting Na+ out and K+ back into the neuron.

This visual representation aids in understanding how ions move across the neuronal membrane to facilitate nerve impulse conduction.
