generated through the flow of positively charged ions across the neuronal membrane.
Your heart's electrical system controls the timing of your heartbeat by sending an electrical signal through these cells. Two different types of cells in your heart ...
The messages carried by neurons are called nerve impulses.

This cycle of an electrical signal followed by a contraction is one heartbeat. SA node and atria. When the SA node sends an electrical impulse, it triggers the ...
Because of these ions, the movement of nerve impulses through individual nerve cells involves both chemical and electrical changes. Before a neuron transmits ...
Messages travel along a single neuron as electrical impulses, but messages between neurons travel ...
An action potential is an electrical signal very much like the electrical signals in electronic devices.
The cell membranes begin to change the flow of ions and a reversal of ...
A nerve impulse, like a lightning strike, is an electrical phenomenon. A nerve impulse occurs because of a difference in electrical charge across the plasma membrane of a neuron.
