The different potentials Flashcards
1
Q
Resting potential
A
The potential difference when the cell is at rest - generated by ion pumps and ion channels
2
Q
Generator potential
A
The change in potential difference due to a stimulus
3
Q
Action potential
A
An electrical impulse along the neurone - if a generator potential is big enough it will cause this
4
Q
Threshold level
A
An action potential is only created if the generator potential reaches a certain threshold level
5
Q
How is the strength of the stimulus measured by?
A
The frequency of action potentials
