Definitions:

Action Potential

A temporary reversal of an electric charge across the membrane of a nerve cell (neuron), allowing for the transmission of nerve impulses.

Axon Membrane

The lipid bilayer covering an axon, critical in maintaining the electrical potential and facilitating the conduction of nerve impulses.

Positively Charged Ions

Atoms or molecules that have lost one or more electrons, resulting in a net positive charge.

Synaptic Gaps

The tiny spaces between neurons, across which neurotransmitters are released to facilitate neural communication.
