Medical · Anatomy Abbreviations
Division of the autonomic nervous system that prepares the body for stress or exertion by raising heart rate and blood pressure, dilating pupils and airways, diverting blood to muscles and mobilizing glucose. Its preganglionic neurons arise from the thoracic and upper lumbar spinal cord (T1 to L2).
Example: Tachycardia and diaphoresis reflect a surge in SNS activity during alcohol withdrawal.
