Nerve Impulses and Action Potentials

Song- 10 Mile Stereo by Beach House

***NOTE***
In a myelinated neuron, the ions outside the axon would be located in the single myelin sheath, so they would be contained, allowing exchange and therefore nerve impulse to occur much faster than if they were scattered like in an unmyelinated neuron.
*********
A stop motion animation short on how nerve impulses and action potentials work for my IB Bio class... Not my best stop motion but this was the first with my new DSLR! (Which is quite lovely because now I don't have to be concerned about focal length or shutter speed) And I did this in a grand total of two and a half hours.

It only took about 169 photos, so it was a quickie. I also used a new program I found on my computer which I like much better than my previous one. This one will make the Boston SM SO much easier..

HELP!!! from 1:30 down to the end I don't get it ;-(

[crypticfable]

@305tanisha what don't you get? :D

[jarrydesque]

I watched a bunch of vids like this and none of them could make me understand it. Now I do! Thank you!

[crypticfable]

@jarrydesque Haha, glad I could help!

[lawlessxwp]

awesome video! thank you :-)

[halfpup]

thanks that was helpful!

@305tanisha The action potential depolarizes the muscle membrane and action potential flows through the center of the muscle fiber causing large amounts of Ca++ to be released from the sarcoplasmic reticulum. After a fraction of a second, Ca++ are pumped back into sarcoplasmic reticulum and contraction ceases until another threshold for action potential is reached and the process is repeated.

Wow thanks so much I was struggling to interpret my textbook but this cleared things up so much. Good job! =D

@305tanisha Maybe you forgot that the one brick of Na represents 3 Na ions and the 1 brick of K represents 2 K ions. That way, the one brick of Na is more positive than the one brick of K. Right?

That has helped sooooo much-thank you.

thank god, finally a video without an annoying, generic person talking. I like how you did this, it's fun.

I get it now! Thanks, wish me luck on my test tomorrow!!!
