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 a hormone, epinephrine is made from norepinephrine inside of your adrenal gland.

Detailed explanation-3: -The adrenal medulla secretes the catecholamines epinephrine and norepinephrine.

Detailed explanation-4: -The neurotransmitter noradrenaline also reaches your adrenal gland, which releases the hormones adrenaline (epinephrine) and noradrenaline (norepinephrine). These hormones travel through your blood to all parts of your body.

Detailed explanation-5: -Epinephrine is a hormone released from the adrenal medulla in response to stress, mediated by sympathetic fibers.
