The adrenal medulla contains granules that secrete which substances?

Explanation:
The adrenal medulla stores and releases catecholamines contained in secretory granules, produced by chromaffin cells. The substances released are epinephrine and norepinephrine. These hormones rapidly prepare the body for quick, short-term stress responses by increasing heart rate and blood pressure, redirecting blood to muscles, and promoting glucose release. Cortisol and aldosterone come from the adrenal cortex, not the medulla, and dopamine is a precursor to these catecholamines but is not the primary product secreted by the adrenal medulla.
