008 The All-or-None Action Potential
Loading...
Uploaded by InteractiveBiology on Jan 3, 2011
http://www.interactive-biology.com - In this episode, I talk about the all-or-none nature of the action potential. Action potentials/nerve impulses either happen or they don't. If the stimulus is strong enough to cause the membrane potential to reach threshold, this will start an action potential.
The action potential starts at the axon hillock and then travels along the axon all the way down to the axon terminals. Watch this video for the details.

WOWWWW. Your examples are so clear, simple and direct. I enjoy listening to such an enthusiastic teacher, unlike my Uni lecturers. I was concerned about a test I have this coming Monday. I've been watching you for the last two days and I'm now looking forward to the test. Many, many THANKS to YOU. Blessings in ABUNDANCE :)
