The tutorial explores what happens to the Action Potential when it reaches the end of the axon. The synapse is the small space between the axon of one neuron and the dendrites of the next. Chemicals called neurotransmitters are used to transfer the potential across this gap.

When you open this site, click on the figure of the synapse. You will then see a powerpoint summary of what is happening in the synapse followed by some questions. This is a very good overview of the events that happen at the synapse. You can also download this ppt (look to the right) if you register. It is worth downloading.

This animation http://www.hhmi.org/biointeractive/motor-cabal-toxins-block-motor-neuron-synapses from HHMI shows how the toxins from cone snails cause paralysis by blocking various functionalities of the synapse. A follow up animation to this is also good: http://www.hhmi.org/biointeractive/prialt-blocks-motor-synapse-fish
