In H&E staining, the adrenal medulla (on the pointer) stains lighter than the adrenal cortex.
The adrenal medulla (Latin: medulla glandulae suprarenalis) is the inner part of the adrenal gland.[1] It is located at the center of the gland, being surrounded by the adrenal cortex.[1] It is the innermost part of the adrenal gland, consisting of chromaffin cells that secrete catecholamines, including epinephrine (adrenaline), norepinephrine (noradrenaline), and a small amount of dopamine, in response to stimulation by sympathetic preganglionic neurons.[1][2]
