Definitions:

Depolarization

A reduction in the difference in voltage across a cell's plasma membrane, which can trigger nerve impulses or muscle contractions.

Excitatory Postsynaptic Potential

An excitatory postsynaptic potential (EPSP) is a temporary increase in membrane potential in a postsynaptic neuron, making it more likely to fire an action potential, usually in response to neurotransmitter release.

Neuronal Membrane

The cell membrane surrounding a neuron, which controls the movement of substances in and out of the cell and facilitates electrical signaling.

Saltatory Conduction

Fast propagation of an action potential at successive nodes of Ranvier; saltatory means “leaping.”
