Neural Control and Coordination.

This chapter explains how the neural system keeps the organs of the body working together. It starts with what coordination means, compares neural organisation in Hydra, insects and vertebrates, and splits the human neural system into its central and peripheral parts. It then describes the neuron, shows how ion gradients make the resting potential, how a stimulus creates an action potential that travels along the axon, and how the impulse crosses a synapse. It ends with the parts of the brain and what each part controls.
