That means no signals are being generated just yet. So let's examine the different types of ions that are present within our body, within our cells. So we see that we have calcium, we have potassium, we have sodium, and we have chloride. Now, when we're at our resting potential, we have a lower concentration of calcium, sodium chloride inside the cell. This is the inside than the outside. On the contrary, we have a higher concentration of potassium ions on the inside than the outside.
