Overview
Action potentials are essential for the functioning of the nervous system, allowing neurons to communicate effectively. They involve a rapid change in electrical charge across the neuron's membrane, primarily driven by the movement of sodium and potassium ions. Understanding the phases of action pot...
Key Terms
Example: Motor neurons control muscle movements.
Example: A typical resting potential is around -70 mV.
Example: During depolarization, sodium channels open.
Example: Potassium ions exit the neuron during repolarization.
Example: Typically around -55 mV.
Example: Myelinated neurons conduct impulses faster than unmyelinated ones.
