Question

Quizplus · Accepted Answer

The sympathetic division of the ANS is involved in the physical responses associated with the "fight or flight" response, which can include pupil dilation. This response could be triggered in John when he saw Martha, suggesting he may have felt excited or nervous upon seeing her. The parasympathetic division, on the other hand, is associated with the "rest and digest" response and would not be as active in this situation. The somatic motor division controls conscious movements, and would not be involved in this automatic response.
