Na+ channels are inactivating, and K+ channels are opening.
Sodium and potassium voltage gated ion channels.
the opening of voltage-gated potassium channels and the closing of sodium activation gates.
Antidromic conduction, or the process of an action potential traveling backwards, is possible. However, regardless of the direction of the action potential, it is propagated by voltage-gated ion channels. Whenever these channels open, there is a sudden exchange of ions, after which the channels snap shut. During this period, known as the refractory period, the channels will not reopen, and thus an action potential will not be able to reverse direction.
An action potential is propagated in a neuron through the activation of various voltage-gated and ligand-gated ion channels. Examples include sodium and calcium channels and nicotinic-acetylcholine receptors.

voltage-sensitive potassium channels
The voltage-gated Ca2+ channels are opened when an action potential releases neurotransmitters from a neuron. A neuron transmits nerve impulses.
voltage-gated calcium channels
During an action potential, the neuron undergoes a rapid change in membrane potential as sodium ions rush into the cell, leading to depolarization. Subsequently, potassium ions move out of the cell, repolarizing the membrane back to its resting state. This rapid change in membrane potential allows for the transmission of electrical signals along the neuron.

K+ ions leaving the cell through voltage-gated channels
In muscle cells the inward current is a sodium + calcium flow through acetycholine activated channels as well as through voltage sensitive calcium channels.
