How does stress affect the nervous system?
Stress and the Brain The stress response tells the brains to send a signal to the adrenal glands they should release adrenaline. This release can cause high blood pressure, increased blood sugar, or increased heart rate. Cortisol damages the brain as well, as it can kill cells in the hippocampus and age the brain.

What are two main physiological systems involved in the stress response?
Physiological Systems Involved in Stress Response: Nervous system. Endocrine system.
What part of the brain controls stress response?
The amygdala is the brain structure that actually detects stress and tells the HPA axis to respond. It can detect both emotional and biological stressors.

What happens when your body is in constant fight-or-flight mode?
The body turns on the “fight or flight” response, but is prevented from turning it off again. This produces constant anxiety and overreaction to stimulation, followed by the paradoxical response called “learned helplessness,” in which victims apparently lose all motivation.
Which nerve is responsible for stress?
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.
