How does our internal electrical system work?

When we squeeze a door knob, or switch on a light, we are able to do so because our nervous system has sent signals to the brain.

When we talk about our brains telling our hands to squeeze the door knob, or about the nervous system sending "signals" to the brain, or about synapses "firing," we're really talking about electricity carrying messages between point A and point B.

It is somewhat like the digital cable signal, carrying the 1s and 0s, that delivers the program "Damages."

In our bodies, though, the electrons do not flow along a wire. Instead, an electrical charge jumps from cell to cell, until it reaches where it needs to go.

Our internal electrical system works by using the cells that have a built-up electrical gradient or energy that can be given off to other cells by direct/neuronal transfer. Neurohormones or transmitters activate the synapses (electrical junctions in the body) that stimulate the brain, nerves, and muscle cells to become active and communicate. This allows us to think, remember, act, and move.
