Explanation:
It's the sodium ion.
When a neural impulse is fired in both neurons, it is always cause by an excited electron in one neuron moving to the other neuron to destabilize the balance of ions trying to keep them at equilibrium. This action either depolarizes or hyper-polarizes the membrane. If it does, then sodium ions--the key deficient ones--can flow into that region of low charge and maintain that state of low charge, keeping the cell membrane stable.
First off, we need to understand that osmosis is typically used with the example of water---
To understand that, osmosis is taking water from a high concentration to a low concentration to make the membrane equal to one another .
Imagine you have a pea, and the pea is about to explode of water. And you have another pea that's shriveled up. You would take some of the exploding water's pea into the shriveled one, therefore making it equal. (Thats my example I like to use!)
I hope this helped!
