Based on the simulation activity, explain how information travels in the nervous system

Information in the nervous system travels via electricity and chemical reactions. A neuron at rest is negatively charged, and when it is stimulated enough by a tiny positive charge, it sends a signal, called an action potential, down the length of its axon by opening and closing sodium and potassium channels at points along the axon. When the action potential reaches the end of the axon, it reaches the terminal buttons and makes them release chemicals called neurotransmitters into their synapses. Then,  they drift across the gap and bind to the next neuron's dendrites, they cause the next neuron to become more positively or more negatively charged.
