Definitions:

Magnitude

Magnitude typically refers to the size, extent, or dimension of an object or phenomenon, often quantified in terms of numerical values in various scientific fields.

Threshold Potential

Voltage on a neural membrane at which an action potential is triggered by the opening of sodium and potassium voltage-activated channels; about –50 mV relative to extracellular surround. Also called threshold limit.

Neural Membrane

The lipid bilayer that encloses the cytoplasm of a neuron, essential for transmitting neural signals.

Action Potential

A rapid increase and subsequent decrease in voltage across a cellular membrane, representing the transmission of an electrical signal along a neuron.
