• A. Thoracicolumbar, close to effector organ
• B. Craniosacral, close to effector organ
• C. Thoracicolumbar, beside vertebral column
• D. Thoracicocervical, beside vertebral column

Answer 1

The correct option is C Thoracicolumbar, beside vertebral column

Sympathetic nervous system( also called thoracic-lumbar outflow as its preganglionic fibres arise from the thoracic and lumbar region of the spinal cord) consists of two sympathetic nerves or chains running from head to the end of the sacral region, one on each side of the vertebral column.
