Neurons
Synaptic transmission
Action potential propagates
along the axon towards presynaptic membrance
Action potential stimulates
vesicles to migrate towards pre
synaptic membrane
Vesicles fuse with membrane whilst the neautrotransitters diffue
across the synapse and bind with receptor molecules on the
membrane of the next neuron
The receptor molecules on the second neurononly bind with specific chemicals
