AP PSYCHOLOGY

Detailed explanation-1: -Your sympathetic nervous system is a network of nerves that helps your body activate its “fight-or-flight” response. This system’s activity increases when you’re stressed, in danger or physically active.

Detailed explanation-2: -The autonomic nervous system has two components, the sympathetic nervous system and the parasympathetic nervous system. The sympathetic nervous system functions like a gas pedal in a car. It triggers the fight-or-flight response, providing the body with a burst of energy so that it can respond to perceived dangers.

Detailed explanation-3: -Adrenaline increases your heart rate, elevates your blood pressure and boosts energy supplies.

Detailed explanation-4: -This rate is constantly being affected by innervations from both the sympathetic and parasympathetic nervous systems. Stimulation by the sympathetic system nerves results in an increase of heart rate, as occurs during the “fight-or-flight” response.

Detailed explanation-5: -Here we will activate your sympathetic nervous system using a famous model pain stimulus: dunking your hand in ice water. As you maintain the hand in the ice water and your hand begins to hurt, your sympathetic nervous system “fight or flight” response will activate.
