The central nervous system (CNS) is the part of the nervous system consisting primarily of the brain and spinal cord.The CNS is so named because the brain integrates the received information and coordinates and influences the activity of all parts of the bodies of bilaterally symmetric and triploblastic animals—that is, all multicellular animals except sponges and diploblasts.
The brain and spinal cord of the central nervous system are connected with organs that have smooth muscle, such as the heart, bladder, and other cardiac, exocrine, and endocrine related organs, by ganglionic neurons. [8] The most notable physiological effects from autonomic activity are pupil constriction and dilation, and salivation of saliva. [8]
A very important type of glial cell (oligodendrocytes in the central nervous system, and Schwann cells in the peripheral nervous system) generates layers of a fatty substance called myelin that wraps around axons and provides electrical insulation which allows them to transmit action potentials much more rapidly and efficiently. Recent findings ...
The afferent fibers of the autonomic nervous system, which transmit sensory information from the internal organs of the body back to the central nervous system (or CNS), are not divided into parasympathetic and sympathetic fibers as the efferent fibers are. [17] Instead, autonomic sensory information is conducted by general visceral afferent ...

The Sistema Interconectado Central (Spanish for Central Interconnected System) or SIC was the main alternating current power grid in Chile spanning all of Chile from Atacama Region in the north to Los Lagos Region in the south. SIC transmitted 68.5% of the national generation and served 93% of Chile's population.
