Quizplus · Accepted Answer

The hypothalamus is responsible for activating the sympathetic nervous system, which triggers the "fight or flight" response in the face of perceived danger. This response prepares the body to either face the threat or flee from it, and includes physiological changes such as increased heart rate, rapid breathing, and dilated pupils. Therefore, in this scenario, it is likely that Nora's hypothalamus has activated her sympathetic nervous system in response to the scary dog running toward her.
