The parasympathetic division of the autonomic nervous system is responsible for returning the body to a normal, relaxed state after a perceived threat has passed. In this scenario, the loud crash triggered the body's sympathetic response, causing the rapid heartbeat and heightened senses. However, once the source of the noise was identified as the dog, the parasympathetic division was able to slow the heart rate and bring the body back to a relaxed state. The somatic nervous system is responsible for voluntary movement, while the spinal cord is a part of the central nervous system and is responsible for relaying messages between the brain and the rest of the body.
