what a good video!! My teacher show us this in class, and the next friday I've my secondo exam with her, and i wasn't understand how to SA node can produce it's own PA. Thank you a loooot!
Very good and clear explanation sir, but i still wondered is the action potential that generated in SA node also have a "refractory period" like the action potential that generated in cardiac myocte ?because from my persepective if we try to compare the graphic between them (sa node vs myocyte) we see that there is almost no actual "resting phase" between the repolarization and the next depolarization
Yes that is right membrane is permeable to potassium only when it is at rest but when a stimulus is generated it increases the conductance of sodium resulting in sodium influx
I really enjoy your concepts.The most favorite part is your gists really filled with goodwill.
Your explanation is simple and elegant. Thank you so much, sir, for making such an excellent video!!!
I’m basically a cardiologist now

One of the easy and best video on RUclips till now
An excellent video, although, a critical point is missing. How Sodium and Calcium moves out of the cell, and Potassium gets into the cell.
Was struggling to understand it. You explained everything so well! Thank you :)
This vedio is amazing,helpful and very easy to understand !thank you soo much
Very nice knowledge given 👍
Thanks for this information.
most welcome
Wonderful video !!!!!! Thank you so much 🤗🤗🤗🤗
Most welcome 😊
Very helpful
Thnku Soo much❤❤

pardon for my english
Actually saved my Biomedical Bmc degree
Bt how Sodium is leak through the cell membrane bcoz membrane are alway permeable to potassium not for Na could you explain plzz
Yes that is right membrane is permeable to potassium only when it is at rest but when a stimulus is generated it increases the conductance of sodium resulting in sodium influx
When the cell is stimulated the Na influx is due to voltage regulated sodium channels
Thank❤🌹🙏 you
Amazing 👏 🙀
❤
Wonderful presentation 🤝 though if you speak dramatically
I'm sbki pdf kaha milegi phle toh download ho jati thi ab mil nhi rhi 😢 ese toh dekhi hui video bhi bhul jaunga
I am not uploading notes any more. Will release compiled notes after all the topics are done.
DO u have your account on Google scholar ?
No. Why?
