    Default Action potential (probably a basic question)

    Hi everyone, I'm a Yr1 medical student, and it's my first real post here! I hope I'm in the right board for this question! A while back, we looked at action potentials. The thing I don't get is - how does the cell restore the resting potential after hyperpolarisation. I keep hearing that it's the Na+/K+ ATPase, but with it's action, doesn't it contribute to a further hyperpolarisation?

    Thanks for the help in advance!

    I didnt get your question exactly.
    Read action potential from ganong or guyton and then ask specifically if any query.
