What nervous system increases hormones?

The sympathetic nervous system is responsible for the "fight or flight" response, which triggers the release of hormones such as adrenaline (epinephrine) and norepinephrine from the adrenal medulla. This activation prepares the body for rapid action in stressful situations by increasing heart rate, blood pressure, and energy availability. Additionally, it stimulates the release of cortisol, a hormone that helps manage stress and metabolism.
