Definitions:

Resting Potential

The difference in electric charge across the neuronal membrane when the neuron is not actively sending a signal, crucial for the initiation of nerve impulses.

Excitatory Postsynaptic Potential

A temporary increase in postsynaptic membrane potential due to the flow of positively charged ions into the postsynaptic cell, making it more likely to fire an action potential.

Action Potential

A momentary change in electrical potential on the surface of a neuron or muscle cell, allowing the transmission of signals.

Repolarization

A phase in the cardiac cycle or neural activity where the cell membrane returns to its resting potential after depolarization.
