- Ca2+ ions enter the axon terminal
- Vesicles containing neurotransmitters move to the plasma membrane and are released by exocytosis
- Neurotransmitters diffuse across the synaptic cleft and bind with recepts on the post synaptic membrane
- This then stimulates the sodium-potassium channels and generates an action potential
Q3. How is a nerve impulse passed from one nerve to the next?
