Document Summary

Define the structure and function of different classes of neurons. Explain the mechanisms in forming membrane potentials. Describe the events and properties of action potentials. Nervous system organization: central nervous system (cns), where decisions are made, protected by bones, bain, skull and spinal cord, ans.
