for your information;
- rising phase of action potential also known as “further depolarization” not “depolarization”
- falling phase of action potential also known as “repolarization phase”
- undershoot also known as “hyperpolarization phase”
- rising phase of action potential also known as “further depolarization” not “depolarization”
- falling phase of action potential also known as “repolarization phase”
- undershoot also known as “hyperpolarization phase”
