Definitions:

Absolute Refractory Period

A period immediately following the transmission of an impulse in nerve or muscle in which a neuron or muscle is not responsive to further stimulation.

Neural Impulse

An electrical signal that travels along a neuron's axon, transmitting information throughout the nervous system.

Milliseconds

A unit of time equal to one thousandth of a second, often used to measure very short durations, especially in scientific contexts.

Absolute Refractory Period

A phase during which a neuron is incapable of firing again immediately after an action potential, ensuring the signal only moves in one direction.
