It outlines brain and spinal cord roles, including spinal reflex circuits that act before the brain registers the event. It then compares somatic and autonomic nervous systems, emphasizing sympathetic versus parasympathetic “accelerator” and “brakes” functions in the stress response, including effects on heart rate, airways, digestion, and reproduction.
