This article, which forms part of the life sciences series and is the second of three articles on the nervous system, explores the major divisions of the brain and their functions. The various ways in which the delicate structures of the brain and spinal cord are protected and supported by the cranial and vertebral bones, the meninges and the cerebrospinal fluid are examined. Neuroglia (glial cells), which form a major component of the total volume of brain tissue, are described. Dementia is discussed briefly to illustrate the effects of a common central nervous system disorder.
