Definitions:

Saltatory Conduction

is a method of nerve signal transmission where the impulse jumps from one Ranvier's node to another, speeding up signal conduction down the axon.

Graded Potential

A shift in the electrical charge across a neuron's membrane, varying in size and leading to the generation of an action potential if a certain threshold is reached.

Action Potentials

A rapid rise and fall in voltage or membrane potential across a cellular membrane, typically in nerve or muscle cells, allowing for the transmission of signals.

Ligand-Gated Channels

Ion channels in cell membranes that open or close in response to the binding of a specific signaling molecule (ligand), allowing ions to pass across the membrane.
