The prefrontal cortex is also part of the system that helps with stress because it makes things appear less scary. The main job of the prefrontal cortex is to control our emotional responses to stress so that we do not get too stressed out.
The amygdala detects things that are scary or dangerous in the environment. It is part of the brain structure that actually detects stress and tells the HPA axis to respond. It can detect both emotional and biological stressors
The hypothalamus is part of the HPA axis that helps respond to stress. The job of the hypothalamus is to wake up the pituitary gland
The Pituitary Gland is part of the HPA axis that helps respond to stress. The pituitary releases hormones, which are the messengers in the stress–response system. These hormones travel out of the brain to the adrenal glands
The Adrenal Gland is part of the HPA axis that helps respond to stress.The Adrenal Gland is located on top of the Kidneys. The adrenal gland releases cortisol, which is the main stress hormone, into the body.
When cortisol is released into the body, its job is to tell the other body parts to react to stress. Cortisol is a messenger that sets other organs in the body into action. It is like the superpower of the stress response system. Cortisol helps the brain to think clearly, sends energy to important muscles, and increases heart rate and breathing
