Solution

Application of stimulus on a resting nerve

Permeability of membrane changes

Na+ ions diffuse into the neuron from the ECF

Positive ions inside axon increases

Membrane potential changes from – 70mV to +30mV this change is called action potential

Polarity reverses and depolarisation takes place

Repolarisation - potassium gates open

K+ ions diffuse out of the axon

The inside of the membrane (becomes less and less positive) becomes negative once again

 ⇓

Axoplasm becomes negatively charged and ECF becomes positive
