Adrenal medulla
The adrenal medulla is composed of chromaffin cells, modified neurons that contain secretory granules filled with the catecholamines, epinephrine and norepinephrine. Although these neurohormones are produced by different cell populations in the medulla, the individual cells cannot be distinguished in this H&E stained section. 1000x
