    The action potential is the mechanism by which nerve cells communicate and conduct information. This short lecture covers topics such as generation of neuronal action potential (nerve impulse), neuronal polarization, depolarization, repolarization, hyperpolarization, resting membrane potential, threshold potential, and refractory period.

      Don't worry i don't understand this video either , but i have watched 10 min video explaining same thing .
      I liked 10 min video better , but this one saves time and serves same purpose for defining "Action potential"
      (I am sure those kids got bored in 2-3 hours long classes so they hate it . )

    Please keep in mind that the ion flow across the membrane occurs only at the nodes of Ranvier. Nodes of Ranvier interrupt the insulation at intervals and this discontinuity enables impulses to jump from node to node. So although the general mechanism described in this video is correct, the location of ion flow is not.
    Also, the resting membrane potential and electrochemical gradients are restored not only by the sodium-potassium pump, but also potassium leak channels and sodium leak channels which are always open.

  • @pascalfroehlich8013
    @pascalfroehlich8013 2 роки тому +4

    The Sodium/Potassium Pump is always working towards make the inside of the cell more negative then the outside of the cell by pumping more +Ions out of the cell (3 Na) then in (2 K). So to say that the pump returns the state of the cell from hyperpolarization to the normal resting potential would be wrong, because the hyperpolarization level of the cell is more negative then the resting potential. This means the Sodium/Potassium Pump would make the charge of the cell in hyperpolarization state more negative and not more positive (which would be needed to reach the normal action potential). What returns the cell from hyperpolarization state to resting potential are the leaky channels who will allow Ions to move acrossed the membranes. Once the -70mV is reached by the leakage, the Sodium/Potassium pump will then maintain the equilibrium of -70mV by counteracting the leaking of the ions....

    • @SexyDave01
      @SexyDave01 6 місяців тому

      Interesting.. I know I'm pretty late but I'll say this anyways.. after action potential occurs, the ratio of the concentration of sodium to potassium is unbalanced because of the efflux of potassium and closure of sodium gated channels. To counter this, Na/K pump pumps out (3 Na) and then in (2 K).
