when you're in the dome parking lot at 2 am when a guy in a hockey mask holding a long bladed knife jumps out at you what system of nerves would arouse your body to action?

Answer 1

In that situation, your body's sympathetic nervous system would be activated, triggering the "fight or flight" response. This response prepares you to react quickly to danger by increasing heart rate, redirecting blood flow to muscles, and releasing adrenaline. These physiological changes enhance your ability to either confront the threat or escape from it.
