Definitions:

Action Potential

A sudden, temporary reversal of the electrical charge across a neuron's plasma membrane, allowing neurons to transmit signals over long distances within the body.

Axon Hillock

The axon hillock is the part of a neuron that connects the cell body to the axon, playing a crucial role in the initiation of nerve impulses.

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.
