| Front | Stages for action potential to travel across synpase |
|---|---|
| Back | When action potential reaches the end of a neurone it causes neurotransmitters to be released into synaptic cleft The neurotransmitters diffuse across to postsynaptic membrane and bind the specific receptors Since receptors are only on postsynaptic membrane, synapses make sure impulses are unidirectional Neurotransmitters removed from cleft so response doesn't keep occuring, they are taken back into presynaptic neurone or broken down by enzymes |
