Action Potential Basics Flashcards
When the membrane is depolarized, ___ channels open
Na+
Na+ then rushes into the neuron and ________
the membrane to produce the action potential
depolarizes
This depolarization shuts off rapidly due to inactivation of the ___ channel
Na+
K+ channels ______the membrane when K+moves out. This
restores the ______potential
repolarize
resting membrane
___ and ___ Movement Underlie the Action Potential

The action potential depolarizes a nerve terminal, causing _____ ions to rush
into the terminal and induce transmitter release via ____
Calcium
