Synaptic Transmission Flashcards
How many steps are there in the synaptic transmission process?
7
First step in the synaptic transmission process?
An electrical impulse is triggered due to a change in charge of the neuron (action potential).
Second step in the synaptic transmission process?
The electrical signal reaches the terminal button where it changes into a chemical message.
Third step in the synaptic transmission process?
The chemical message is released from the vesicles as a neurotransmitter.
Fourth step in the synaptic transmission process?
The neurotransmitter travels across the synapse to the next neuron.
Fifth step in the synaptic transmission process?
The neurotransmitter binds to receptors on the next neuron, to pass the message on.
Sixth step in the synaptic transmission process?
Neurotransmitter is either reabsorbed (reuptake) or destroyed by enzymes in the synapse, returning the neuron to a resting state.
Seventh step in the synaptic transmission process?
The chemical message is converted back to an electrical message and travels down the axon.
