ANATOMY

Detailed explanation-1: -The adrenal medulla secretes catecholamines, hormones that help your body respond to stress. Catecholamines include adrenaline and noradrenaline, also known as epinephrine and norepinephrine. Within moments, your body releases adrenal medulla hormones to boost organ functioning.

Detailed explanation-2: -Adrenaline is a hormone released from the adrenal glands and its major action, together with noradrenaline, is to prepare the body for ‘fight or flight’.

Detailed explanation-3: -As part of the response, the adrenal glands release hormones including adrenaline, norepinephrine, and cortisol, which triggers the cascade of physiological responses, including an increase in temperature, heart rate, respiration rate, blood pressure, and energy expenditure.

Detailed explanation-4: -Through a combination of nerve and hormonal signals, this system prompts your adrenal glands, located atop your kidneys, to release a surge of hormones, including adrenaline and cortisol. Adrenaline increases your heart rate, elevates your blood pressure and boosts energy supplies.
