Question

Quizplus · Accepted Answer

Pupil dilation and rapid heartbeat are both associated with the "fight or flight" response, which is mediated by the sympathetic nervous system. The parasympathetic nervous system, on the other hand, is associated with the "rest and digest" response and has the opposite effect on physiological processes like heart rate and pupil size. The somatosensory cortex is involved in processing sensory information from the body, while the peripheral nervous system includes all of the nerves that lie outside of the brain and spinal cord.
