Action Potential 2 Flashcards
1
Q
What is the first step of Action potential?
A
Positive Na+ ions diffuse to the next region of the axon causing depolarisation of next region
2
Q
What is the second step of Action Potential?
A
If enough Na ions diffuse into this next region of the axon; thus region depolarises to the threshold
3
Q
What is the third step of Action Potential?
A
When the threshold is reached in this next section of the axon, voltage gated Na ion channels open in this next region of the axon
4
Q
What is the final step of Action Potential?
A
More Na ions diffuse into the next region
