Question

Quizplus · Accepted Answer

The movement of a nerve impulse is characterized by the passage of ions through the membrane of a neuron. Specifically, the impulse involves the movement of sodium ions into the cell and potassium ions out of the cell, which creates a temporary depolarization of the membrane potential. This electrical signal then moves down the length of the neuron via the opening and closing of ion channels, until it reaches the end of the neuron and triggers the release of neurotransmitters.
