Beginning with an exploration of nerve cells, this volume of the Encyclopedia of the Human Body discusses the parts of the central and peripheral nervous systems and how they work together in reflex responses and understanding sensory information. Major areas of the brain and the autonomic and peripheral nervous systems are covered. The five senses are discussed in relation to the nervous system. The history of the research on the nervous system is presented and the future of research in this field is considered. Current controversies and dilemmas of scientists performing this research are explored. Nervous system disorders, symptoms and treatments are explored, including multiple sclerosis and epilepsy. The reference concludes with information about maintaining a healthy nervous system, a comprehensive glossary, and resources for further information including Web sites and contact information for organizations and national health institutions. The set provides a complete, comprehensive reference source for students interested in the human body. Each book in the ten-volume set introduces and describes a specific body system, including the parts and function of each system, the history of discovery, related diseases and treatments, as well as possible future advances in research. Detailed illustrations and diagrams, including an eight-page color insert, provide a visual reference for written material.
