Describe the processes which occur that allow synaptic transmission

Question:

Describe the processes which occur that allow synaptic transmission

Answer:

1) The action potential arrives at the axon terminal

2) Voltage-gated Ca2+ channels open

3) Ca2+ enters the presynaptic neurone

4) Ca2+ signals to neurotransmitter vesicles

5) Vesicles move to the membrane and release the neurotransmitter by exocytosis

6) Neurotransmitter binds to receptors

7) Signal initiated in post-synaptic cell
