What is released by the adrenal cortex?

The adrenal cortex is responsible for producing and releasing several important hormones, one of which is cortisol. Cortisol, commonly known as the stress hormone, plays a vital role in various physiological processes. It helps regulate metabolism, reduce inflammation, and control the body's response to stress. Additionally, cortisol helps maintain blood sugar levels and assists in memory formulation.

The role of the adrenal cortex is largely distinct from that of the adrenal medulla, which produces epinephrine and norepinephrine, hormones that are involved in the body's immediate stress response or 'fight-or-flight' reaction. Glucagon, on the other hand, is produced by the pancreas and is primarily involved in glucose regulation. Therefore, the hormone that specifically originates from the adrenal cortex is cortisol.
