The structure of the human nervous system

In order to proceed to the study of mental processes, we need to first get acquainted with the biological bases of mental, ie the structure and cellular mechanisms of the nervous system. The human nervous system is divided into two large sections - the central nervous system (CNS) and the peripheral nervous system (PNS). By CNS include spinal cord and brain. PNS also often divided into two sub-division - NA somatic and vegetative (autonomic) NA. In the vegetative NA in turn emit sympathetic and parasympathetic divisions.
