Susanna ; So, at the end of the process the charge balances, out and its back to normal... But what about the concentrations of sodium & K+ ? Now there are more Na + ions & less K+ ions than before the whole process Started. How is that handled ? does the pump slowly balance it out ?
You say that ALL the Na-gates open during the action potential, but isn't it just the ones at the axon hillock and then the others open when the potential reaches them down the axon? I guess the question I am asking is about the definition of an action potential. I have heard it used for the entire process as well as for just on gate opening.
Thank you so much for these videos! Love your style of teaching! God bless you!
Unique presentation. Congratulations. Thanks deeply
Excellent lecture. Getting to understand it more.
Thank you for these amazing videos , please share with us ur handout , i really need it .
very nice vid susanna.
Wish you a _merry christmas_ & a happy new year.

I thought potassium pumps open at zero.
