Question

Quizplus · Accepted Answer

Molly's mobilization of energy, including increased heart rate and sweating, is due to the activation of her sympathetic nervous system, which is responsible for the body's "fight or flight" response in dangerous or high-stress situations. The somatic nervous system controls voluntary movements of the skeletal muscles, but it does not account for the physiological responses to a perceived threat. Similarly, the skeletal nervous system is not a recognized body system, so it is not a applicable response. The parasympathetic nervous system is responsible for the "rest and digest" response, which has the opposite effect of the sympathetic nervous system and would not be activated in this situation.
