MICROANATOMY

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: -With regards to the nervous system, stress will activate the sympathetic nervous system which in turn activates the adrenal glands.

Detailed explanation-3: -You may be familiar with the fight-or-flight response-a process initiated by the sympathetic nervous system when your body encounters a threatening (stressful) situation. The hormones of the adrenal medulla contribute to this response.

Detailed explanation-4: -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.
