I understood better in this short time than the 2 hour lecture from my professor. Thank you for this video
Same same😁😁
Stop insulting others....one or other is always better...
How about paying attention during those 2 hrs?

@@mritun2751you that lecturer ?
Don't worry i don't understand this video either , but i have watched 10 min video explaining same thing .
I liked 10 min video better , but this one saves time and serves same purpose for defining "Action potential"
(I am sure those kids got bored in 2-3 hours long classes so they hate it . )
Wow... 4 weeks into the semester and 3:24 minutes explained what I thought was hard to understand lol... Thanks for this
you are not kidding lol same dude !!!
Guys those 4 weeks made it easy for you to understand all this ... You can't just watch a 3 min video and learn everything from it 🤟 THOSE LECTURES MATTER BUT NOT THE WHOLE 3 HOUR BORING LECTURE 😩
@@parkourisart9651 nope. didn't touch my lecture at all and started doing my lectures right before my exam, didn't understand. pulled up this video and instantly understood. this 3 minute video won vs 1 week of teaching
hahaha what the f!ck, I HAD A 2 HOUR LECTURE ON THIS AND THIS ABSOLUTE BOSSMAN HAS JUST SLAPPED IT UP IN 3 MINS.
good job sir!
True mam ✨
Please keep in mind that the ion flow across the membrane occurs only at the nodes of Ranvier. Nodes of Ranvier interrupt the insulation at intervals and this discontinuity enables impulses to jump from node to node. So although the general mechanism described in this video is correct, the location of ion flow is not.
Also, the resting membrane potential and electrochemical gradients are restored not only by the sodium-potassium pump, but also potassium leak channels and sodium leak channels which are always open.
So would it happen right after the dendrites and then shoot all the way to the other end when threshold is reached?
💯 MORE VIDEOS PLEASE 💯
Can you pin this comment please?
a whole year trying to find someone that can explain this to me. Thanks a lot you made it easy and concise.
I am a pharmacy student from Iraq. Can you teach me how to read?
I have spent ages trying to understand action potentials, this video is the best explanation I have found and really helped me understand FINALLY!!! Thank you so much

i have an exam later, checked this for a brief review and this made me understand the topic more. thanks
best explanation I ever listened in life about neuron action potential.
THIS IS THE BEST VIDEO TO UNDERSTAND ACTION POTENTIAL.
I HATED THIS TOPIC BECAUSE I COULDN'T UNDERSTAND IT EVEN AFTER WATCHING MULTIPLE LECTURES.
THANK YOU FOR THIS MAN !
This is the best explanation i have come across! Thank you so much
Oh god man you’re saint, I love you. I’m currently preparing for my biochemistry midterm and my mind was such a mess after reading about ion channels and you’ve explained everything in 3 minutes better than anyone else. Thank you!
Finally I understood the AP for the first time in my life 😮😍😍😍
Thank you 🌹 🌹🌹🌹🌹
Best Explanation ever. simple. clear and straight to the point ❤
I am amazed at how concise this was! Thank you.

FACTS!!!
Too true! 😂
And made zero sense 🙃
Speed pharmacology dude

Do you feel the NEED FOR SPEED ?????????
This was so great, hours of zoom lectures plus super long chapters were all wrapped up in this short video!!
Sir, you're doing a very great job, as a student I'm very satisfied and so clear.
I have looked at so many videos, this is by far the BEST one I've watched. Thank you!
Yo mans just cleared the topic in 3 minutes, legend.
you should be hired by harvard, you're a pro in teaching
this is saving my AP psychology mark thank youuu
thank you for the simplest explanation ever
the best video on this subject that i've found on youtube!!
Thank you for making this subject more easy to understand.
wow i actually understood that! thank you for explaining it alongside the graph cause it really helped.
My course has a 20 min lecture video about this yet I've learnt it in 4 minutes from this video. Brilliant. Thank you so much.
U r great
Definitely one of the easiest way to learn about AP!!
You just earned a new sub, love it when people make things simple and direct.
Simply incredible. 4-week course in 3 min , imagine if you were the teacher and had more time.....
Truly the best video in youtube .. THANK YOU for making my day man 🙏
Thank you for this short and super simple explanation. You are a saviour ❤️
The first step of repolrization is closing the Na channels then opening the K channels...not opening K channels immediately as you mentioned... Just a small note... Great video 👏👏
this was the clearest and best explanation i have seen yet, thank you :)
Great video! Finally someone explains it in a language I can understand!
I would say finally someone explains it...
I know, right? Was looking for an easier short video that will put all the terminologies in.
I have my exam tomorrow and this video literally connected all the dots for me, thank you!!
This is the most beautiful explanation in the planet.
thank you, you're explanation was short and sweet and explained everything perfectly
I am a pharmacy student from Iraq. Can you teach me how to read?
Thank you - much easier to understand now.
best explanation on the internet! thanks
best video i have ever seen for action potential , thank you so much
THANK YOU!
You made it simple and easy to understand!
This is best explanation ever!!!
Universities: give me your money and here’s 3 hours of lectures
This guy:
Thank you for this video. Better than going to class.
That person at beginning makes all our exam stress vanish! 😂😂😍
You really made it wicked easy to understand 😜
After so many videos, yours was the easiest to understand.. Thank you so much
Oh my God unbelievable, I understand way better than I did in my 2 hours seminar ,thank you soo much
woww, thankk you so much , sir . really appreciate your work. Now i know why its negative 70 inside ,bcoz we r comparing it with outside .
This genuinely helped me. Thank you
11th grader here and can't be more grateful, I didn't understand a word of this particular topic at school
This was VERY helpful. Thank You!
awsm explanation .. will recommend to all my friends to watch your lectures..
The Sodium/Potassium Pump is always working towards make the inside of the cell more negative then the outside of the cell by pumping more +Ions out of the cell (3 Na) then in (2 K). So to say that the pump returns the state of the cell from hyperpolarization to the normal resting potential would be wrong, because the hyperpolarization level of the cell is more negative then the resting potential. This means the Sodium/Potassium Pump would make the charge of the cell in hyperpolarization state more negative and not more positive (which would be needed to reach the normal action potential). What returns the cell from hyperpolarization state to resting potential are the leaky channels who will allow Ions to move acrossed the membranes. Once the -70mV is reached by the leakage, the Sodium/Potassium pump will then maintain the equilibrium of -70mV by counteracting the leaking of the ions....
Interesting.. I know I'm pretty late but I'll say this anyways.. after action potential occurs, the ratio of the concentration of sodium to potassium is unbalanced because of the efflux of potassium and closure of sodium gated channels. To counter this, Na/K pump pumps out (3 Na) and then in (2 K).
THANK U FOR HELPING ME PASS MY TEACHERS USED LIKE 10 HOURS TO EXPLAIN IT BUT STILL DIDNT MAKE SENSE
this video helped me so much! God bless you man🖤
