What are the three basic parts of the nervous system?

What sequence do your impulses follow?
Nerve impulses begin in a
dendrite, move toward the cell body, and then move down the axon
. A nerve impulse travels along the neuron in the form of electrical and chemical signals. The axon tip ends at a synapse. A synapse is the junction between each axon tip and the next structure.
