Which gland secretes epinephrine and norepinephrine to help the body respond to stress?

• A. Pituitary Gland
• B. Thyroid Gland
• C. Adrenal Glands
• D. Pancreas

Answer: (C)

When the body faces stress, it needs a rapid, system-wide boost of energy and alertness. The adrenal glands, especially the inner part called the adrenal medulla, release epinephrine (adrenaline) and norepinephrine (noradrenaline). These hormones unleash the fight-or-flight response: heart rate and blood pressure rise, airways open up, blood is redirected to the muscles, the liver releases glucose for quick energy, and pupils dilate. This coordinated surge helps you respond quickly to a threat. The other glands listed have different roles—pituitary regulates many processes, the thyroid sets metabolic rate, and the pancreas manages blood sugar—so they don’t provide the rapid stress hormones epinephrine and norepinephrine.
