Thank you so much!!!! You made this very easy to understand!

Respected sir if you could explain that how action potential is transfeered from one Na vgc to neighboring Na vgc along axon, sir i will be thankful to you. In vedio it is only explains generation at one Na vgc

Aren't schwann cells primarily in the PNS? Oligodenrocytes form the myelin sheaths in the CNS
reem meshal (9 месяцев назад)
thank you!
Malia Ahmed (9 месяцев назад)
This is great, but I believe the channels are only located on the nodes of Ranvier, not on the myelin sheath. The myelin sheath speeds the passage of the ions.
devid Roy (1 месяц назад)
sir how threshold potential is achieved by impulses . can u xplain plzz
Speed Pharmacology (9 месяцев назад)
Your'e correct. I focused so much on making this as easy to understand as possible that I completely forgot to mention that.
Official Kelby (9 месяцев назад)
Definitely one of the easiest way to learn about AP!!
Lizzy G (9 месяцев назад)
thank you, you're explanation was short and sweet and explained everything perfectly
Diego Garrido Mendoza (10 месяцев назад)
I agree! The best explanation by far I've found. Can I find more about this topic (neuronal electro-physiology) in your channel?
Flash Games (10 месяцев назад)
i googled action potential for retarded people and this video came up... THANKS!
Kania Rimu (11 месяцев назад)
you rock!

Unresolved contradictions in the science of the origin of life. The membrane theory of biopotentials leads to a dead end. Watch the video for details: https://youtu.be/0yMTnXI6UEA
MakParis Supreme (11 месяцев назад)
why is this so boring!?!?!?!?!? (this is why i don't watch the vids for the my homework)
Mikayla Elmashni (1 год назад)
So when does the actual action occur (like kicking your leg)?
Mikayla Elmashni (11 месяцев назад)
Thank you so much!!!!!!
nomaan syed (11 месяцев назад)
Mikayla Elmashni when the nerve stimulates the muscles in your legs for that particular action. This video shows how a nerve conducts (how the information travels inside th nerve).... It will first go from your eyes to your brain. And then your brain will send the signal to your leg muscles to kick. And thats how you kick something. :)

Please can anyone help me understand the purpose of Sodium activation and inactivation channels? And why Potassium has only one activation gate?
Trendy Gillies (1 год назад)
You did make it easy. I keep forgetting how it works no matter how many times I read. I think a video would help me to stick the material in my brain. Thank you!

how long is the axon
Nand Javia (1 год назад)
It can be pretty long, sometimes from spinal cord to toes.
GoodCat01210 (1 год назад)
Is it bugging anyone else that hes showing the action potential happening within the section covered by the myelin sheath? As far as i know, this process occurs at the Nodes of Ranvier.
Speed Pharmacology (1 год назад)
you're right. ion flow across the membrane occurs only at the nodes of Ranvier. however, the main purpose of this video was to illustrate only the very basic idea of how neuron action potential works. obviously it's an oversimplified explanation
ghoyatul muna (1 год назад)
Wow amazing.... thanks !!! :)

If both sodium and potassium are positive why is the inside of the membrane negative?
Laraib Rafique (3 месяца назад)
Because of the presence of other types of negative ions such as RNA and Protien
Studying Decay (2 года назад)
+Habiba Q Thanks for the answer. This is correct for anyone else reading. I had my professor explain it to me and this is basically what he said.
Habiba (2 года назад)
Although both sodium and potassium ions are positive and are moving in and out of the cell, in total there are more positive ions moving out of the cell than entering the inside. The sodium-potassium pump is moving 3 sodium ions outside whilst moving only 2 potassium ions inside. So that's why the inside of the cell is said to be RELATIVELY negative than the outside. So basically it just has less positive ions inside of the membrane in comparison to the outside.
Vince Li (2 года назад)
There are a lot of negatively charge proteins inside the cell membrane.
Josh Henderson (2 года назад)
The Na+/K+ pump is NOT responsible for the membrane potential to go from hyperpolarization to its resting state. This happens through the passive movement of ions through leak channels!!
Misa Sadin (1 год назад)
Josh Henderson I
Glitterfm2133 (2 года назад)
Josh Henderson no it is the NA+ k+ pump
Jana Ross (2 года назад)
thank u so much wow

Finally I get it!!!
Theater Kid (2 года назад)
Thank you, sir. You're awesome!
arjun , (2 года назад)
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 .
