ANATOMY

Detailed explanation-1: -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-2: -It consists of three layers: Zona glomerulosa (outer layer). Zona fasciculata (middle layer). Zona reticularis (innermost layer).

Detailed explanation-3: -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-4: -Introduction. The adrenal medulla, which is composed of pheochromoblasts/chromaffin cells, forms the gray core of the adrenal gland. These cells synthesize and store the catecholamines norepinephrine, epinephrine, and dopamine.

Detailed explanation-5: -Adrenal glands are small, triangular glands that sit on top of each kidney. An adrenal gland is made of 2 parts. The outer region is called the adrenal cortex. The inner region is called the adrenal medulla.
