GENERAL HISTOLOGY

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 gland is made up of the cortex and medulla. The cortex produces steroid hormones including glucocorticoids, mineralocorticoids, and adrenal androgens, and the medulla produces the catecholamines, epinephrine, and norepinephrine.

Detailed explanation-4: -Epinephrine is a hormone released from the adrenal medulla in response to stress, mediated by sympathetic fibers.

Detailed explanation-5: -epinephrine, also called adrenaline, hormone that is secreted mainly by the medulla of the adrenal glands and that functions primarily to increase cardiac output and to raise glucose levels in the blood.
