Excellent video! Made the textbook make much more sense. I'm still not understanding when potassium returns to the cell. Is this after the hyperpolarization with the Na⁺/K⁺-ATPase pump?

@errrccc Жыл бұрын

Yes, Na⁺/K⁺ ATPase pump returns the cell to its resting membrane potential, and the cycle repeats with another action potential.

@Joeythegoats 2 жыл бұрын

In 5:48. I studied that at plateau some potassium start to gonna close? (I think not all) what do u think of this.

@paulsparrow2442 7 ай бұрын

Why is the resting membrane potential negative 70 mv? The cell is filled with potassium which is a cation. Also how/when does potassium renter the cardiac cell?

@georgeacosta4742 2 ай бұрын

It’s a comparison from inside the cell to outside. There are more cations outside the cell compared to the potassium inside the cell so -70 is just what the comparison difference is from in to out.
