Lights, Camera, Action Potentials!

An action potential is a short-lasting event in which the electrical membrane potential of a cell rapidly rises and falls, following a consistent trajectory. Action potentials occur in several types of animal cells, called excitable cells, which include neurons, muscle cells, and endocrine cells, as well as in some plant cells. In neurons, they play a central role in cell-to-cell communication.

[@ersinasliturk7861]

This is the best explanation of how neurons work! Thanks to CarletonU folks!

[@MyZac01]

learned more in five minutes then school could teach me in 2 years :*(

[@demorttete239]

so useful I wish my study will be more correct in next years
because I want to know true afects like this video so nice

[@alondrapacheco6847]

.yay finally i get it thank you soooo much!!

[@patrickharrison783]

Narrated by Caillou's dad.

[@CarletonUvideos]

Thanks for all the feedback. I'm thrilled the video has been helpful for so many people!

[@smack007]

Thanks so much, my textbook was making my head spin all day but this video really made it easier!

[@mickiemox]

Wow just wow. Couldnt understand a thing from when i reading my textbook but watching this... I understood it thank you!

[@taekwonwelchify]

this is by far the best and most accurate video I've watched on action potentials in the past hour. thank you!

[@tanyaaugustine6765]

I teach high school neurobiology, anatomy & phsyiology & biology and this is the best video I've seen yet. Thank you!

[@asma16cool]

Simple illustrations, smooth voice, informative. Thank you c:

[@B3bita1215]

Excellent video!!! Love how simple, yet so informative this video is :)

[@mustafabadri1499]

It makes so much sense and very easy to understand

[@elmanu6538]

Perfect video, that explains everything in simple terms yet understands the complexity of how the system works.

[@BR-hi6yt]

Just switches basically - why all the terminology and laborious step by step explanation of SWITCHES?

[@floriath]

Great video! Deserves a mn likes.

[@alessandracoleman2673]

Thank you so much for this video. It's very helpful and very simple to understand.

[@mrs.carlson]

This is fantastic! Great supplemental video clip for my A/P class.

[@branver1172]

Thanks for posting! This was clear and interesting. And, oh my goodness, the nervous system is a complex and beautifully designed.

[@Triplex136]

Oh noez, Mr. Lee sent me here.. time to take dem notes. 5th Period ftw.

[@bumble21bee43]

The person teaching this is really a God sent.... Much more comprehend able than d rest.....

[@forest_sail]

Helped my 7th graders enormously. Thank you for creating this

[@ilz7_3]

Thank you for this. Most helpful in understanding this topic.

[@asiastandifer6283]

Thank you for this video!! It really made this concept easier to understand!

[@smilerkris]

That was super good! Thanks :)

[@farafeu2670]

excellent animation!

[@BentAlward2011]

It was to hard to understand tell I saw this demo
Thank you

[@pellen96]

Fantastic video! Thanks

[@maryamsabbagh220]

Thank:) you it's really helpful& super easy.

[@leanne3213]

Great video! Very informative and understandable.

[@Veehon11]

you need to reverse the sodium gate and potassium gate since the sodium should be on the right and the potassium on the left when the AP is moving to the right.

[@whostolemyTV]

Great animations, clear and concise, a lot of help

[@Hex180]

Personally I would've accelerated, but still got the point, thanks.

[@woyorus]

Great video!

[@mridulrambani4718]

nice video. So helpful for me.

[@demorttete239]

so useful I wish my study will be more correct in next years
because I want to know true afects like this video so nice

[@HaleyChartier]

Go Dr.Hellemans 🎉

[@VladCodY]

Very useful indeed!

[@tribehut3]

really helpful...clearly shows what happens in a way i can understand. thank you

[@katjathesaurus3800]

Vampire eyes... HISS! .. or i cslL them zombies

[@yodaydyxz1752]

It's a good demo.

[@thatsmybriefcase]

Nice video!

[@mam09d]

Best video ever.

[@LifeIsForEmos8D]

Excellent Video! I have a question, though. How do Potassium an Sodium ions pumped into/out of the axon return to their original levels after an AP? Is there a reversal?

[@davesenften4118]

+LifeIsForEmos8D Active transport via the Na+/K+ pumps restore the neuron back to resting potential...this process is called repolarization.

[@d.beautygirl8805]

FANTASTIC

[@trunkcvageta5000]

Thanku so much sir it ws really helpful may God bless u

[@megancanter3771]

mid video

[@tashibombay]

Very clear explanation. Thanks!

[@angela-hm7rq]

seria genial si tuviera subtitulos

[@amdem5886]

Thanks alot .....

[@kellysimons9184]

RMP (Resting membrane potential) is -90 mV

[@trunkcvageta5000]

It is the case when post synaptic membrane is muscle membrane sarcolemma whereas in case of neurons its around -70

[@mikemcmanus1574]

a lot going on here

[@sinamoazami2493]

perfect video

[@شعلهحیران]

Excellent👏👏

[@mianshahidmianshahid4212]

superb

[@faridalam798]

Thanks a lot

[@nomsapraise7042]

Thank you!!!!

[@johngaines2344]

what

[@komposteramig]

Thank you, most comprehensive and understandable explanation of this I've found so far!

[@Mr604bourne123]

one of the best learning videos to remember
