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.
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.
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.
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
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
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.
Very well explained...all confusions solved

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

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

You have saved me 😮💨
Thanks from the depths of my heart
This is the best video for this topic
Excellent sir. Understood the concept very well
Please make more such videos
جزاك الله خيرا
Excellent sir🎉
Tooooo good!!
Thank you so much
Thank you so much ❤
Excellent explanation 👌
Thank you so much. It helped ALOT
Keep going it's amazing
Amazing 👏👏👏
Thanks alot
Soooooooo good♥️♥️
For all the students comes here to understand this topic after watched many video
he is wrong about potassium channels closing in phase 2...
He is
Yeah he is
It is right potassium channel is closed and calcium channel is slow
He is right and best lecture ever
Thank you so much ❤❤❤❤❤❤❤❤
Phase 2 .calcium chanel where located?? T tubul DHP receptor? ?
👏🏻👏🏻 thank you for your work.
Most Welcome!
keeeppp going.👍👍👍
Thank you, I will
It's to esay thank you so much
Good 👍
Thanks
Very easy to understand 🙂
Thanks for liking
👍 good 👏
Nice profile name
روعه
Subhanallah

Sir plz uplaod autacoid pharmacology and chemotherapy pharma plzzz
We are currently focusing on Physiology. But we will cover everything eventually.
@@NonstopNeuron plz sir kindly upload
👍🏻👌🏻👌🏻
❤❤
great video but hard to understand because of the accent
Is it that easy!!!!!
Yes.
Sary concept ka Satya Nas kar dia
thank you so much 🤗
You're welcome 😊
