Verified step by step guidance1
Understand the General Adaptation Syndrome (GAS), which describes the body's short-term and long-term reactions to stress, consisting of three phases: alarm, resistance, and exhaustion.
Focus on the alarm phase, which is the initial reaction to a stressor, triggering the body's 'fight or flight' response.
Recall that during the alarm phase, the sympathetic nervous system activates the adrenal medulla to release specific hormones.
Identify the hormone released by the adrenal medulla that prepares the body for immediate action by increasing heart rate, blood flow, and energy availability; this hormone is adrenaline (also known as epinephrine).
Differentiate adrenaline from other hormones listed: melatonin regulates sleep, cortisol is released later during prolonged stress (resistance phase), and insulin regulates blood sugar but is not primarily involved in the alarm phase.
