Brief Explanations:

The sympathetic nervous system is activated during stress - like situations such as preparing for a job interview. It triggers the body's "fight - or - flight" response, increasing heart rate, blood pressure, and releasing stress hormones. The peripheral nervous system is a broader category that includes both the autonomic and somatic nervous systems.
