ACTION POTENTIAL
Something happening in the cells
How cell signals itself to do something |
|
Definition
1. Big dramatic change. Wants to get it back to original state.
2. Inside of cell is negative/outside positive
3. Sodium positive wants to be attached to negative
4. Potassium in positive
5. Signals organels to do what they do - driving force
6. Sodium wants action potential to spread |
