Action Potential

An action potential is a brief electrical signal that travels along the nerve cells in our body, allowing them to communicate. When a nerve is activated, it undergoes a rapid change in electrical charge across its membrane, flipping from negative to positive and back. This process creates a wave of activity that moves along the nerve, transmitting information, whether it's a touch or a thought. Action potentials are essential for functions like muscle movement, reflexes, and sensation, playing a vital role in how our bodies respond to the environment.
