Neurotransmitter Synapse 3D Animation Closeup

Synapse signal transmission with acetylcholine

1. Overview synaptic cleft, axon

2. Action potential changing voltage, so that the...

3. ...Ca++ -channels open

4. Exocytosis: Synaptic vesicles discharging

5. The neurotransmitters are discharged into the synaptic cleft

6. Protein molecules are binding neurotransmitters, and also..

7. ..Ion channels, so the ion channel opens, if sufficiently stimulated

8. K+ -ions pour into the synaptic cleft through an ion channel

9. Na+ -ions pour into the next nerve or muscle cell

10. The voltage difference causes an action potential in the next nerve or muscle cell

11. What happens to the neurotransmitters if they are discharged:...

12. ...They bounce back and forth in the synaptic cleft...

...until the enzyme Acetylcholinesterase (violet) splits it into its parts,...

...so it can reenter the axon terminal cell and the synaptic vesicles.
