Action potential question.. in Communication option

did anyone else absolutly love the action potential question?? in the communication option..
. man im soo glad i spent that time to actually make sure i understood it, and what do u know.. it was actually in the exam i was actually able to answer it when everyone else just was like wat the..!!

what is "action potential" ???

*is officially lost now*

 

[bscienceboi]

Action potential relates to the change in electrical charge by the movement/diffusion of ions, and how an 'response' is triggered.

wat was the question?

 

[*ccs*]

I HATE ACTION POTENTIALS lol

ahaha!! ^__^ That's goo! XD

yay I thought that question was okay but I didn't write a page or so. LOL


This is what I wrote:

Depolarisation must reach a threshold (minimum stimulus required to generate response in the nerve cell) which is at least 50 mV more than the resting potential of -70 mV. No action potential if depolarisation is below this level . Therefore not all stimuli generate an action potential.

That sounds right

Thanks. I hope so LOL

You should NEVER walk out of an exam until time is up. Never.

I don't care how many times you have to review your answers, never do that.

...Yeah I'll have to remeber that for my chem phys and SDD tests then... I just can't believe that's SEVEN marks down the drain!
