Definitions:

Local Potential

A transient change in the electrical charge of a neuron's membrane, which can lead to an action potential if it reaches a certain threshold.

Threshold Level

The level of stimulation that must be exceeded for a reaction or response to occur, marking the limit between inaction and action.

Action Potential

A temporary reversal of electrical charge across a cell membrane, leading to the transmission of nerve impulses.

Myelinated

Refers to axons that are covered with a fatty sheath called myelin, which increases the speed at which electrical impulses propagate along the nerve cell.
