What are the two divisions of the autonomic neural system?

The CNS includes the brain and spinal cord and is the site of information processing and control.The afferent nerve fibres transmit impulses from tissues/organs to the CNS.The efferent nerve fibres transmit regulatory impulses from the CNS to the concerned peripheral tissues/organsThe autonomic neural system is further classified into sympathetic and parasympathetic neural system. The Visceral nervous system is the part of the peripheral nervous system that comprises the whole complex of nerves, fibres, ganglia, and plexuses by which impulses travel from the central nervous system to the viscera and from the viscera to the central nervous system.
