Definitions:

Action Potential

A momentary change in electrical potential on the surface of a cell, especially a nerve or muscle cell, that occurs when it is stimulated, leading to the transmission of an electrical impulse.

Neurotransmitters

Chemical messengers that transmit signals across a chemical synapse, from one neuron (nerve cell) to another, influencing a variety of physiological functions and behaviors.

Action Potentials

Electrical impulses that travel along the axon of a neuron, signaling the transmission of information.

Potassium Ions

Positively charged ions (K+) crucial for various biological functions, including the regulation of heartbeat and muscle functions, and critical in establishing the resting membrane potential in neurons.
