ANATOMY

Detailed explanation-1: -The adrenal medulla, the inner part of an adrenal gland, controls hormones that initiate the flight or fight response. The main hormones secreted by the adrenal medulla include epinephrine (adrenaline) and norepinephrine (noradrenaline), which have similar functions.

Detailed explanation-2: -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-3: -Adrenaline is released by the adrenal glands in the body. Hypothalamus sends the signal of releasing adrenaline whenever there is a situation of flight, fright, or fight. Adrenaline accelerates the rate of heart along with the flow of blood in the vessels and helps in tackling emergency situations.

Detailed explanation-4: -Your adrenal glands are endocrine glands located on top of your kidneys. They produce many important hormones, including cortisol, aldosterone and adrenaline.
