When voltage-gated potassium channels open, potassium ions move out of the cell

Question

When voltage-gated potassium channels open, potassium ions move out of the cell restoring the resting membrane potential. The action potential triggers the opening of sodium channels further down the axon. The action potential triggers the opening of voltage-gated potassium channels. In mammals, actions potentials propagate more slowly because they are insulated by a myelin sheath. An action potential is initially triggered by the opening of voltage-gated K+ channels. The propagation of a nerve impulse relies on changes in membrane potential along the length of a nerve. The influx of sodium ions makes the membrane potential more positive. The action potential can only travel in one direction along the axon.
