Messages are transmitted electrically within neurons, and chemically between them. The communication between neurons takes place across synapses (the gaps between neurons)
A message reaches the end of one neuron (the pre-synaptic cell), triggering the release of neurotransmitters from vesicles (sacs) located at the terminal button
These chemicals are released into the synapse, and are taken up by the next neuron (the post-synaptic cell)
Excess neurotransmitter is reabsorbed by the pre-synaptic cell
Excess neurotransmitter is reabsorbed by the pre-synaptic cell
