AP PSYCHOLOGY

Detailed explanation-1: -Your sympathetic nervous system is the part of your nervous system that carries signals related to your “fight-or-flight” response. That makes it a key part of your response to stressful situations.

Detailed explanation-2: -Your parasympathetic nervous system is a network of nerves that relaxes your body after periods of stress or danger. It also helps run life-sustaining processes, like digestion, during times when you feel safe and relaxed.

Detailed explanation-3: -The brain is what controls all the body’s functions. The spinal cord runs from the brain down through the back. It contains threadlike nerves that branch out to every organ and body part. This network of nerves relays messages back and forth from the brain to different parts of the body.

Detailed explanation-4: -The autonomic nervous system is one of the major neural pathways activated by stress. In situations that are often associated with chronic stress, such as major depressive disorder, the sympathetic nervous system can be continuously activated without the normal counteraction of the parasympathetic nervous system.

Detailed explanation-5: -The parasympathetic nervous system is responsible for energy building, food digestion, and assimilation. It functions to restore homeostasis and is active when the body is at rest and recuperating.
