Action Potential Flashcards
1
Q
What is Action Potential
A
Temporary change in charge between inside and outside the membrane, an electrical current that passes along the axon
2
Q
What is resting potential
A
Uneven balance maintained
3
Q
What is depolarisation
A
Sodium channels open- more positive inside, causes short burst of electrical energy along axon
4
Q
What is repolarisation
A
Action potential finished- sodium channels close and potassium channels open, positive charge outside membrane
5
Q
What is hyperpolarisation
A
Temporary overshoot until balance is achieved
