Action Potentials Flashcards
1
Q
What is the wave of depolarization?
A
Wave of depolarization: Na+ moves into axon segment by segment, in myelinated axons depolarization only occurs at the Nodes of Ranvier (saltatory conduction)
2
Q
Make sure you know each phase and associated information
A
:)
3
Q
What is the absolute refractory period?
A
depolarization to repolarization
4
Q
What is the relative refractory period?
A
hyperpolarization to resting state
5
Q
How do anesthetics work?
A
block APs by binding to voltage-gated Na+ channels and prevent depolarisation
