The Action Potential
zhlédnutí 1,2KPřed 4 lety
The action potential is how the neurons send signals, or heart muscles create beats, or endocrine system controls the release of hormones. The action potential is the rapid rise and fall of the membrane potential. And the membrane potential is the charge difference in/out the cell membrane. The membrane potential is defined by the moving potassium and sodium ions through the membrane using ion ...

Thank you I really appreciate it
thank u so much
For Problem #4: A = 1.44(10^-14), you forgot to multiply by pi
How did youy find the value of Kinetic Energy?
Mistake in Q3. Question states 0.018 J, but answer states 0.0018 J.
Hi sir give me your what's up number please
I’m so thankful for you ❤️❤️
Thank you for helping me clutch up, BIG UP THE MANDEM
Brilliant!
Great 👌👌👌
God bless you
Thank you so much ❤️
Professor can you upload the slides, because it’s not convenient to use only video , thank you beforehand
I agree with you bro
Which software application u used to prepare slides?
I use the apple's keynote to prepare the presentation and animations. Simply, it is the Power Point for Mac OS.
Yeah, wave sounds were so nice🌊
Wow, great background sounds at 6:53. So relaxing) Probably all this animations and graphics take from you a lot of time. Thanks proffessor for such efforts 👍
Thank you for another great lecture, professor!
Good job
Thank you for interesting lecture
