Donnan Equilibrium? Driving Force? What in the world do those things mean? Well, you’re about to find out. In this video I explain the concept of Donnan equilibrium and show how that leads to the Driving Force that’s responsible for generating an Action Potential, otherwise known as the Nerve Impulse. If you want to know even more details about Donnan Equilibrium, check out my Notes on the Nervous System.

You mentioned that the Na+ needs to reach a donnan equilibrium of 58MV, and when it is not near the resting membrane potential state of -50 to -80MV, the NA+ feels uncomfortable. Thus, causing sodium ions to rush into the cell. However, how does rushing into the cell make it “positive?” I thought the point of sodium to move into the cell was to become more comfortable, which meant reaching -50 to -80MV?
Thank you in advance!

for questions about the define 58mV, look at the netnst equation
