Nerve chemicals {neural chemical} {nerve chemical} are hormones, ions, modulators, receptors, regulators, transmitters, and structures.
transverse motion
Only biological cells use transverse ion motion to make depolarization wave. If axon has nodes of Ranvier, depolarization jumps from node to node and transverse ion motion is same strength in all directions around axon circumference. If axon has no nodes of Ranvier, transverse ion motion is all around axon circumference but is most at least-resistance point. Ions repel each other, so differences are small. Depolarization waves travel down lines on axon surfaces, following least-resistant path, and can spiral down axon.
