in the membrane that covers axons
Na+ channels are inactivating, and K+ channels are opening.
Sodium channels. A neuron's membrane potential may depolarize for many reasons (neurotransmitters, mechanical deflection, electrical synapse, etc). When that membrane depolarizes to the point of its threshold of activation, then voltage gated channels open up an allow an influx of sodium into the cell. This rapidly depolarizes the cell's membrane, causing that upward peak or rising phase to occur.
membrane voltage gated ion channels open and close with changes in the membrane potential
Tetrodotoxin (TTX) is a natural inhibitor and blocks single sodium channels in an all-or-none manner.
Sodium and potassium voltage gated ion channels.
Voltage-gated Na+ and voltage-gated K+ channels
Voltage Gated channels
Inactivation gates of voltage-gated Na+ channels close, while activation gates of voltage-gated K+ channels open.
Voltage Gated channels
There are voltage-gated ion channels and ligand-gated ion channels, and since both are stimuli the term stimulus-gated is a redundancy.
Voltage-gated Sodium ions and Potassium ions channels

Na+ channels are inactivating, and K+ channels are opening.
Na+ channels are inactivating, and K+ channels are opening.
It is a channel through a membrane that can be opened or closed by chemical or electrical events.
