• Action potential is a nerve impulse
•It is caused by the sodium potassium pump as it is pumping a positive and negative charge •The cytoplasm inside the cell will be a -charge will the fluid out side would be a + this is when the neuron is polarized •the sodium potassium pump then pumps in positive charges into the membrane, cause a reaction so then it would reach the peak and then repolarize when transferring electrical signals, throughout the cell |
