Document Summary
By the end of the next two weeks you should be able to: What are the advantages of saltatory conduction: describe what is meant by the all-or-nothing principle of action potential conduction, explain what determines the direction of the conduction of the action potential. Expectations: you should have already drawn an action potential. An analogy used to describe an action potential is a human wave" like the ones seen during a sporting event. Depolarization or hyperpolarization: na, k, cl, ca+2. Weekly activity: check out this ted talk* todd kuiken: a prosthetic arm that feels. This talk will help give you great context for how the next four modules integrate together. Why or why not: think about it: babies are pretty uncoordinated when they are born. Structure matters, and as we"ve seen nerve cells have a very specific structure. Nerve cells are asymmetrical, meaning you cannot cut them down the middle and have two equal parts.
