GENERAL HISTOLOGY

Detailed explanation-1: -Epinephrine is released by your adrenal glands in response to stress. This reaction causes a number of changes in your body and is known as the fight-or-flight response.

Detailed explanation-2: -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-3: -Epinephrine is a hormone released from the adrenal medulla in response to stress, mediated by sympathetic fibers. The word epinephrine derives from epi, meaning above, and nephros, the root word for kidney, because the gland sits atop the kidney.

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. The adrenal hormones help regulate several bodily functions including metabolism, blood pressure and your body’s response to stress.

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.
