Final answer:

When a nerve sends a message, sodium ions flow in, followed by potassium ions flowing out, leading to depolarization and repolarization.


Explanation:

When a nerve sends a message, it involves the movement of ions such as sodium and potassium. Initially, sodium ions flow into the cell, causing depolarization. Subsequently, potassium ions flow out, leading to repolarization and the closure of sodium gates.
