Neurotransmitters Action Potential Neurone Cleft Postsynaptic Receptors Stages

Action potentials cause neurotransmitter release into the synaptic cleft, diffusion to postsynaptic receptors, and eventual removal to end the response, ensuring unidirectional transmission.

Action potentials trigger neurotransmitter release into the synaptic cleft, where they diffuse across to bind to receptors on the postsynaptic membrane, ensuring unidirectional transmission. Enzymes then remove neurotransmitters to terminate the response.

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
