Sir you really should be awarded for making such awesome legible diagrams..which help us students form our own answers..and not just do copy pasting text from TB..literally the best teacher😄💯💯💯
YOU ARE AMAZING!!!! I WISH THERE IS AN ANOTHER WORD. BUT YOU ARE JUST LITERALLY AMAZING. Thank you so much! Never found easy but you helped me so much and saved my time. Best wishes.
Great videos! You need to add a edit to the video because K+ is the most permeable ion to the resting membrane potential. Na+ is only slightly permeable to the resting membrane and Na+ tricking into the cell makes the cell just slightly more positive than it would be if only K+ flowed. Therefore, at resting membrane potential, the negative interior of the cell is due to much grater diffusion of K+ out of the cell than Na+ diffusion into the cell. :)
Great video. Some clarification on the establishment of the resting membrane potential: The Na/Ka-pump doesn't produce the cells resting membrane potential. It produces the electrochemical gradients that facilitates the movement of the ions across the membrane (and transport of other molecules across the membrane). What causes the resting membrane potential is the conductance or permeability (from the high number of potassium leak channels in the membrane) to potassium. This high permeability to potassium allows potassium to be the major contributor to the overall resting membrane potential, and since the equilibrium potential for potassium under physiological conditions is -90 mV, the resting membrane potential is accordingly close to this number, at around -70 mV.
Thank You sooo much. I am taking A&P right now and I am currently learning about the nervous system. Your video helped me understand this potential more completely.
i had so much problems with understanding how the cell maintain its resting membrane potential i watched alot of videos and lectures,,,but i did not understand it thanks to u clearing some small but very important key points making it easy to understand u r the best :* very grateful :)
Potassium is much more permeable than all those other ions. It is going against its electrical gradient, and so only a little bit will go out because of this, cause there is still negatively charged Cl- outside. However this tiny bit going against the electral gradient is enhanced because there is so much potassium inside the cell that it wants to move out against its concentration gradient. So instead of a tiny bit of potassium moving out, we have a few potassium moving out.
Thank you so much!!! I am incredibly incredibly thankful to you! Drawing it out step by step clarifies this incredibly complex process! Your drawings made all the difference! I will keep watching your videos!!! THANK YOU!
1. how the voltage gated channels (Na+) open at the time of stimulus for depolarization. 2. how the next site of depolarized site starts showing the depolarization for the conduction of nerve nerve i,e gets depolarized. 3.which causes the breaking of synaptical vesicles in the synaptic button.
All information I have ever read has always stated that the flow of Sodium through leaky channels is low and the flow of K+ ions through leaky channels is high. This means you have very few sodium ions moving in and more k+ moving out. This net flow of electrical charge out in conjunction with the Na+/K+ channel causes the -70 mv difference across the membrane. ????
NaK-ATPace doesn’t have much role in action potential - it doesn’t have to. For example: amount of sodium inside cell is measured in mmol - ion channels (within ms) lets some picomole inside. Also ATPaces capacity is rather low on transporting ions. One thing is easily forgotten - diffusion of ions, when they enter in or out cells. The ions doesn’t stay in place for long - ask mr. Brown :). It’s the flux of potassium that in the end makes resting potential to recover. Check Ouabain studies on nervous system. Doc
your vedio is so great! Excellent illustration! It helps me a lot! Would you please make another vedio on action potential? I'm looking forward to your lecture!:)

Love from India
I understand so deeply 👍👍😀
Best presentation of the resting membrane potential I have seen so far, great work!
Looking forward to your action potential Video.

U r an amazing. ....wonderful teacher. ....respect for u sir.....💖💖💖
Thank You sooo much. I am taking A&P right now and I am currently learning about the nervous system. Your video helped me understand this potential more completely.
your series is the most helpful, informative, easiest to watch on the net. thanks for doing this :)
I have been studying for hours and ur video pulled it all together
I have a terrible neuroscience teacher, so thank you for teaching me more than I learned all term.
really waiting for an action potential . i now understand thanks to your detailed sketches
i had so much problems with understanding how the cell maintain its resting membrane potential i watched alot of videos and lectures,,,but i did not understand it
thanks to u clearing some small but very important key points making it easy to understand
u r the best :*
very grateful :)
your lectures are super awesome....and give a complete insight of the topic,thanks
Your ability to explain anatomy is amazing!!!!!
Amazing.... Dude
Ur style of teaching is a fabulous

Made the topic very clear! Also explaining the negative charge inside beautifully.
Thank you so much!!! I am incredibly incredibly thankful to you! Drawing it out step by step clarifies this incredibly complex process! Your drawings made all the difference! I will keep watching your videos!!! THANK YOU!
Love this video. Was so fun to watch and now I have a better understanding of resting potential, my textbook just complicates it with bland diagrams
Thanks , sir . This was an Awesome lecture . Really helped me lots
This video was really very helpful, but if possible, please make a video for action potential as well 🙏🏻
thanks heeps. its not that precise, but I am glad it seems that way:)
Action membrane potential
Hi. It is a great video. Can you explain the role of calcium in neuronal excitability? What happens to it, if hypercalcemia occurs.
best video Ive seen explaining everything all in one place! thanks
You explain stuff so well. this topic is one of the easiest and yet I just wasn't getting it till I ate across you
thank you
I love how easy you made this to understand. 👏🏻👏🏻👏🏻
Bless you sir. I've been dying trying to understand the topic and this video helped greatly.
This was a very helpful videio. Just want to say thanks for all the time and effort and has really helped me a lot.
This saved my life for high school anatomy! thank you!
Beautiful and very professional
great drawings + cohesive thoughts= better students!! Great videos!! Thank you
You really made studying interesting and easy! THANK YOU.
Great video! It really helped put all the pieces together in a very understandable way
It was as if a light went off in my head when you were describing the electrical and concentration gradients. Thank you.
Excellent video and explanation. Thank you Armando.
Best video on RMP
I hope you will still upload your Action Potential video!? :)
I love your videos! I don't think I'll be able to pass neuroanatomy without them! I really hope you make upload an Action Potential video soon :D
Wow! It makes more sense how you explained it. Great job,
THANK YOU! your videos are VERY HELPFUL!! ACTION POTENTIAL PLEASE!!
Thank u for this video...I strongly intended that you and your family will be blessed by god..
The best explanation ever !
Thank you so much
I so enjoy your videos! It's more easy to understand with your presentation.
When your phone rang, I thought it was ours and started looking around XD
This was great Thank you! I hope you DO make an Action Potential video and many more!!
SERIOUSLY, you are awesome!!!!! thanks for making this. it really helped me understand RMP.
Good demonstration, looking forward seeing ur videos
1. how the voltage gated channels (Na+) open at the time of stimulus for depolarization.
2. how the next site of depolarized site starts showing the depolarization for the conduction of nerve nerve i,e gets depolarized.
3.which causes the breaking of synaptical vesicles in the synaptic button.
I'd love to see your rendering of the Papez circuit (its path).
Thanks and I appreciate the time folks like you take to do these videos.
You are a true genius.
it's amezing bro,
I all way view - easy to understand and helpful for seminar & exam points. ..
thanks 🌹
GREAT VIDEO ! I was so confuse about this ! Thanks a lot for the help !

So interesting explanation!! But little fast!!
best explanation ever
Thanks sir, very grateful. Amazing artwork.
I dont really understand from other videos .
Kindly post about action potential @armando

really like the way of explaination......
Understood perfectly .. thank you
This helped a lot. Very dummy-proof - but also enough formal for school-use.
You my friend, are a G.
very easy to understand thanks bro....
a very awesome explanation...
Thank you kindly for your video. This was very helpful.
That video is brilliant, learned a lot. Thank you
Well explained and nice diagrams, thanks!
VERY HELPFUL review for me!!!!
So what is the sodium/potassium pump's role? Is it to restore the resting potential?
