Pregangliotic neurons of the sympathetic division of the autonomic system originate in the thoracic and lumbar (thoracolumbar) levels of the spinal cord and send axons to sympathetic ganglia, which parallel the spinal cord.
The great confrontation we came to call the Cold War had quite suddenly become the next stage of world history. What began in Iran in 1946 lasted for 45 years, until the dissolution of the Soviet Union in 1991.
