The Autonomic Nervous System is the involuntary functioning part of the nervous system that controls the internal organs of the body. It is composed of sympathetic and parasympathetic systems which work in opposition to each other. Together the two systems control cardiac muscles, smooth muscles, and glands. This classic chart of The Autonomic Nervous System shows the pathways of both the parasympathetic and the sympathetic systems. Clearly labeled lines lead from the spinal nerve to the ganglia and the corresponding organ. The spinal cord, spinal nerves and the organs affected are illustrated. A detailed cross section of the human torso and head shows the spinal nerves. All nerves are labeled.
