Action Potential In Cardiac Muscle || Heart || Cardiovascular Physiology

[@vidyachathoth8207]

Very well presented. I just had one doubt though. My understanding is that in the plateau phase, potassium channels remain open, and potassium efflux continues along with the calcium influx. That is why the membrane potential neither rises nor decreases. At the end of the plateau phase, the calcium channels close while potassium channels continue to be open, leading to repolarization. Please clarify.

[@NonstopNeuron]

Yes, some potassium channels are open during plateau through which potassium leaks out. But much more of them open as we reach towards final repolarization. I hope it helps. It was nice to discuss this extra detail.

[@AnilP-ll7kd]

Yeah they are slow k+ channels they can't match the calcium influx .

[@kejsik6374]

for me this video was great for reviewing a physiology concept from last year. my memory is quite bad, but videos like this that are concise, yet comprehensive are super helpful! action potential seems much easier than i remembered it to be lol.

[@niwanshisharma2282]

Finally! Understand what really happens.... Thank you so much ❤️💀

[@dr.user.]

thank you this was the most comprehensive video to describe exactly the polarized membrane and how to restore the balance after the movements of ions during action potential

You have saved me 😮‍💨 Thanks from the depths of my heart

Thanks

[@aryangojiya7466]

It's to esay thank you so much

[@danielgabbay112]

he is wrong about potassium channels closing in phase 2...

[@1rrrrrrrrrrr544f]

He is

[@AnilP-ll7kd]

Yeah he is

[@madi_ha]

It is right potassium channel is closed and calcium channel is slow

[@pratapchandradas3129]

Very easy to understand 🙂

[@mohsanijaz8162]

Sir u said cell membrane inside is negative in resting membrane potential but u said k+ions leave out side where these k+ions come because u said membrane is negative at resting membrane potential

[@NonstopNeuron]

They are there inside the cell only. I think you need to understand the electric activity at a more basic level. Also it seems you don't know that K is the main intracellular electrolyte. For now watch my video on resting membrane potential. It may help.

Sary concept ka Satya Nas kar dia

[@kingxkhalid7780]

Is it that easy!!!!!

[@NonstopNeuron]

Yes.
