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: -The inner part of the adrenal gland (a small organ on top of each kidney). The adrenal medulla makes chemicals such as epinephrine (adrenaline) and norepinephrine (noradrenaline) which are involved in sending nerve signals.

Detailed explanation-3: -Epinephrine, also called adrenaline, is both a hormone and a neurotransmitter. As a hormone, it’s made and released by your adrenal glands, which are hat-shaped glands that sit on top of each kidney.

Detailed explanation-4: -Norepinephrine is produced in the inner part of the adrenal glands, also called the adrenal medulla. The adrenal medulla also makes adrenaline (also known as epinephrine).

Detailed explanation-5: -First, is that the definitions of hormones and neurotransmitters allow for multiple chemicals to be called both. In other words, their definitions are not exclusive to one another. Second, epinephrine fits both definitions. Epinephrine is secreted into the bloodstream by the adrenal medulla, making it a hormone.
