I'm doing an anatomy assignment, and I don't really understand how signals travel down a neuron. I'm supposed to explain this using words like Sodium, potassium, channels, action potential, and other words. Can someone please explain how signals travel down a neuron?

If the neurons interact, neurotransmitters in the next neuron called receptors are activated and are bound to the synapse through specific molecules. The receivers interpret the message and analyze it, and transfer it to the next neuron. 4. The message enters the cortex, eventually.

Explanation:

is there any answer choices to this?
