Mineralocorticoids are produced by he outermost adrenal cortex cell layer. They are important in regulating the mineral and salt content of the blood. Subsequently , they regulate both water and electrolyte balance in body fluids.

Glucocorticoids are produced by the middle cortical layer. It produces cortisone and cortisol. Glucocorticoids help promote normal cell metabolism and help the body to resist long term stressors. They also help by reducing pain by inhibiting pain causing molecules.
