Question

Quizplus · Accepted Answer

The sympathetic nervous system is responsible for the activation of the "fight or flight" response. It is the branch of the autonomic nervous system that prepares the body for perceived threats or stressors by increasing heart rate, dilating pupils, and diverting blood flow to the muscles. The parasympathetic nervous system is responsible for the "rest and digest" response and works to counterbalance the sympathetic nervous system. The efferent and afferent nervous systems are subdivisions of the peripheral nervous system that deal with motor and sensory information, respectively, and are not directly involved in the "fight or flight" response.
