7: Summary of neuronal transmission

Summary of neuronal transmission

Use the example of two neurons making contact to summarize neuronal transmission. Point to the cell on the top and indicate that electrical impulses flow in the direction toward the terminal. Remind the students what happens when impulses reach the terminal; neurotransmitters are released, they bind to their receptors, and new impulses are generated in the cell on the bottom. Explain that this is how information travels from neuron to neuron.
