General Adaptation Syndrome (GAS) - The three stages of the body’s general adaptation to stress: alarm, resistance, and exhaustion., Sympathomedullary (SAM) system - This system triggers the "fight or flight" response by releasing adrenaline, increasing heart rate, and preparing the body for immediate physical action during acute stress., Hypothalamic-Pituitary-Adrenal (HPA) system - The longer-term system activated during ongoing stress, leading to the release of cortisol to manage the body’s response to stress over time., Role of adrenaline in stress response - A hormone released from the adrenal glands that prepares the body to cope with stress by increasing blood sugar, enhancing memory and alertness, and suppressing non-essential functions like digestion., Cortisol - A hormone released by the adrenal glands as part of the HPA system, playing a critical role in dealing with prolonged stress by regulating energy and inflammatory responses., Fight or Flight Response - The initial stage of stress response, which prepares the body to either fight or flee from the stressor. It activates the SAM system and results in the release of adrenaline., Acute Stress - A type of stress that is short-lived and typically triggers the fight or flight response, where the body quickly returns to normal once the stressor has passed., Chronic Stress - A prolonged state of stress where the body remains in an activated state for an extended period, often leading to health problems like heart disease and weakened immunity.,
