... 48. Describe the nerve impulse as it travels along a nerve fiber and across a synapse. Ans: A nerve impulse is a wave of depolarization and repolarization, during which sodium ions first move into a neuron and then potassium ions move out of a neuron. This is called an action potential. When the act ...
