Nasim is driving on a snow-covered road, and her car begins to slide. the quick behavioral response and the increased heart rate and respiration she experiences are most likely due to the nervous system. the feeling of relief and decrease in heart rate and respiration once she has the car under control again are most likely due to the nervous system.

a) parasympathetic; sympathetic
b) sympathetic; parasympathetic
c) autonomic; somatic
d) somatic; autonomic

The given blanks are filled with the sympathetic and parasympathetic nervous systems.  

•The autonomic nervous system consists of two parts, the parasympathetic and sympathetic nervous systems.  

•The system, which activates the flight or fight response at the time of threat or danger is the sympathetic nervous system, and the system, which restores the body to a state of calm is the parasympathetic nervous system.  

•The sympathetic nervous system discharges the hormones norepinephrine and epinephrine, which increase the heart rate and prepare the body for fight or flight response.  

•On the other hand, the parasympathetic nervous system discharges acetylcholine hormone, which reduces the rate of heart and makes the body in a state of calm and composure.  

Thus, in the given case, the quick behavioral response and the enhanced respiration and heart rate experienced by Nasim are most likely because of the sympathetic nervous system. While the feeling of relief and the reduction in respiration and heart rate is most likely because of the parasympathetic nervous system.
