The Action Potential
Details of Depolarization,
Repolarization, and the Refractory
Period
The Action Potential:
Depolarization Phase
What kind of Na+ channels are these and
where are they?
Ach
(At the motor end-plate)
What is the magnitude of the voltage
change (on graph) required for this
cell to generate the all-or-none
Action Potential?
The Action Potential:
Repolarization Phase
When is it possible to generate
another Action Potential in this
cycle? Explain why.
Unidirectional Propagation
Why is this important?
Refractory Period
