Quizplus · Accepted Answer

The sympathetic nervous system is responsible for the fight or flight response, which involves increasing heart rate, muscle tension, and sensory awareness in response to a perceived threat. This is likely the system causing Hannah's reaction to the frightening noise. The limbic system is also involved in emotional processing and memory, but it is not specifically responsible for physiological responses like increased heart rate. The parasympathetic nervous system is responsible for the body's "rest and digest" response, which is the opposite of the fight or flight response. The central nervous system refers to the brain and spinal cord and is not a specific system involved in this physiological response.
