Which hormone is associated with the fight-or-flight response?

• A. Insulin
• B. Oxytocin
• C. Adrenaline
• D. Cortisol

Answer: (C)

The hormone associated with the fight-or-flight response is adrenaline. Adrenaline, also known as epinephrine, is produced by the adrenal glands and plays a crucial role in preparing the body to respond to stressful situations. When an individual perceives a threat, adrenaline is released into the bloodstream, leading to various physiological changes. These include an increase in heart rate, dilation of air passages in the lungs, and enhanced blood flow to muscles, all aimed at optimizing the body's ability to either confront the danger or escape from it. This response is vital for survival and has evolved as a mechanism to deal with acute stressors. Adrenaline works rapidly, ensuring that the body is primed for immediate action. The fight-or-flight response is a critical aspect of the body's natural reaction to perceived threats, and adrenaline is the key hormone that mediates these changes.
