Answer :
during action potential, positively charged _sodium_ ions move inside the cell.
Sodium ions move inside the side during action potential.
- This stage of action potential is called depolarization.
- This open voltage gated sodium channel.
What is action potential?
- Action potentials (those electrical impulses that send signals around body) are nothing more than a temporary shift (from negative to positive) in the neuron's membrane potential caused by ions suddenly flowing in and out of the neuron.
- It consists of phases:
- depolarization
- overshoot
- repolarization.
- An action potential propagates along the cell membrane of an axon until it reaches the terminal button.
