when the sodium ions and potasium ions switch possitions arent they suppose to return to normal due to active transport, or was it only intended to show the first part

[psychenova]

Yes, it's only for the first part. Certainly, they are changed back by the Na+/K+/ATPase.

ok, i understand the whole teaching of tht. But the music! wat on earth!?!?! wat is a hat check clerk anyway. and at an ice rink? It's soooo random.

[psychenova]

Sure, it's not related to subject at all. It just gives a nice ambient feeling.

Certainly, if you have a good song about the action potentials, I will be glad to change it :)

[moutaff]

what song is this?

[psychenova]

It's the Let x=x by Laurie Anderson.

[IcyRealmster]

I wonder how much weed went into that song.

its been years since A&P, is it -70mv +40mv?

[tenshiato]

This is exactly what I need! Thanks for posting this :)

Problem? 3Na 2K

This isnt a very good animation, it doesnt show the sodium potassium pump, and the action potential moves too quickly compared to the sodium intake and potassium output.

@xvsoothsayer Really? I plan on going into the social sciences. Does this apply to everyone or just bio majors/med school?

[xvsoothsayer]

if you're in high school and learning this, retain it. This is going to come back to get you.

[xvsoothsayer]

@CaptainJenna7 It depends on the neuron. -70 is a way of simplifying it into an average number. But, the definition is -40 to -90 mV. It's just that different types of neurons with different forms of relationships need more or less to fire.

[xvsoothsayer]

@smokey566 Resting Membrane Potential is -40 to -90 mV. The threshold for an all or none reaction (action potential) to occur is +15-20 mV from it's original RMP. From there, the influx of sodium will peak at about +100 mV before re polarization begins.

In other words, if you start at -40 RMP in a specific neuron, Threshold for that cell would be -25 to -20 mV, and the action potential will peak at +60 mV.

@mickomoo haha AP biology, that was a joke. Actually, all AP classes are jokes.
