Resting Membrane Potential of Neuron

[@rileyvandyke6298]

These videos have helped me in just about every class I've taken for my undergrad! would highly recommend

[@dhanikaamarasekera9110]

that's hard work explaining sir, you deserve more views

[@lcia_lciani]

I swear I can not believe how easily I learnt this topic by the help of this fantastic lecture. Thanks you very much

[@Muuip]

Well deserved title of "Professor". Thank you.

[@abcmovies1349]

You are one of the best teacher I have ever met, Thanks AK lectures

[@adernain]

Damn it THANKS A LOT, I had problems understanding these things, I am studying medicine in german, but I find your english lessons more understandable!

[@suzyho2169]

Are you from Germany?If not,is it hard to study medicine in German language?

[@swimalison6297]

Always so helpful in understanding!! Thanks

[@zonishbaloch110]

THANK YOU SO MUCH!!! SIR, YOU SAVED MY LIFE! SALUTE TO YOU!

[@mayanksangam9205]

It's awesome. Thank you sir.

[@larrynil1]

Actually you are doing a geart job,its glorious.😙👍

[@chicken456]

What do you mean when you refer to an "electric force"? Thank you for your videos, they have been the key for me this semester!

[@Muuip]

All knowledge of all institutions shall become available in this format.

[@adamsmtonga]

thank you, you saved my life am definetly going to get an A in the test

[@saadrehman362]

did you get an A?

[@mayanksangam9205]

What was the result?

[@casualcasual1234]

May I ask some questions? 1. I have calculated the voltage difference only due to Na+ to be 61mV, so if I do 61 - 87, I can't get the value of -70mV, which is the resting potential, why? 2. if K+ is constantly getting out and Na+ is constantly getting in, won't the cell lost too much K+ and gain too much Na+?

[@austinquick3860]

This is made up for by Na/K pumps that are helping offset the leaks when the ions diffuse through their gradient.

[@IGMFSH]

there are more ions than just na and k, some are organic anions, cl, and ca.

[@IGMFSH]

more importantly though is the open k channels causing k leakage (losing positive ions creates a more negative overall charge)

[@EpicSelenium34]

This is a great video. My one question is: where does the Na+/K+-ATP pump come into this?

[@sangjuktabiswas2532]

Could you tell me why the cell membrane is preferably more permeable to Potassium than to Sodium?

[@Lakshmi235Lakshmi]

Thank you so much 🙏🙏🙏🎩🎩🎩

[@DestinedFX]

thank you so much, really helpful

[@lizchatham5940]

I love your voice.

[@mubmub1358]

Hi, great video but can you explain where the 2.3 comes from in the Nernst equation?

[@dobeeeeval]

A little late, but for anyone watching this in 2019 (or after), the 2.3 comes from converting log base e to log base 10. So [2.3026 * log_10(x) = ln(x)]

[@mayankgargmbbskmcmanipal]

I LOVE YOU! SIR

[@heatherbloom5426]

sir I have a question..if due to equilibrium the concentration is maintained the inside will contain more positive potassium than outside positive sodium so at the end inside should be more positive..???

[@gbk757]

I'm TWO YEARS too late. But basically, there's active transport taking place as well which he mentions for a bit before going back to the topic of the video. In the bottom left diagram, it is the green part.

[@nmarvlonam9908]

thank you a lot

[@nikhilbhaskar6181]

So what’s the use of pump during RMP.

[@aritraghosh4761]

Many many thanks

[@youssefrefaat1594]

I love you

Hi, where did 2.3 come from (in the equation)???

[@mastertea8996]

Why is there initially more potassium inside the cell than outside the cell?

[@imagination7710]

The Na/K-ATPase is constantly moving K into the cell

[@imagination7710]

Also I think the cell is already negative due to the anions on the cytoplasmic side. The electrostatic attraction prevents diffusion of K+ out of the cell.

[@collinskarani6287]

Potassium ions are more permeable than sodium ion hence the rate of positive potassium ions leaving the cell is higher than that of sodium getting into the cell

[@abelathanos3803]

best

[@dyoomah17]

We took something called " leak channels " .. do you mean leak channels by saying ( facilitated transports of K & NA )

[@AKLECTURES]

dyoomah17 Hi! Yes! Leaking refers to the movement of ions down their electrochemical gradient through some sort of protein membrane.

[@dhanikaamarasekera9110]

you also call them Na/K pumps aswell

[@nathaniele1835]

its not the same thing. leak channels move the ions down their concentration gradient. therefore no ATP is needed. NA/K pumps move the ions against their gradient. therefore atp is needed
