The human nervous system is designed to regulate somatic and visceral organ function and provide for memory and intelligence, all through the use of rapidly-conducted electrochemical signals. The principle tissue component of the nervous system is nerve tissue, one of the four primary tissues of the animal body. Nerve tissue consists of two types of cells: neurons, which are specialized to conduct electrochemical signals, and supportive cells, which provide physical and metabolic support and electrical insulation to neurons.
