Synaptic Transmission

• 1. Action potential occurs when information is sent down an axon
• 2. Electrical impulses reach the end of a neuron and the vesicles bind with the presynaptic membrane
• 3. Once binded, neurotransmitters are released from the vesicles.

  Only found on one end of the neuron ensuring direction of travel
• 4. Neurotransmitters travel across the synaptic cleft and attach to the receptors on the post synaptic membrane.
• 5. The chemical message is converted back to an electrical impulse and it continues down the next neuron
• 6. Stimulation of post synaptic receptors result in either excitation or inhibition of postsynaptic membrane and determines if neurons fire or not.
