In turn, the pituitary gland produces hormones that stimulate the adrenal glands to produce hormones.

The hypothalamus produces hormones that stimulate the pituitary gland. The adrenal glands interact with the hypothalamus and pituitary gland. The cortex produces steroid hormones such as cortisol, aldosterone and testosterone. The cortex produces hormones that affect blood pressure and blood sugar levels, growth and some sexual characteristics. The medulla and produces epinephrine and norepinephrine, which are commonly called adrenaline and noradrenaline.

The medulla produces the hormones that regulate the body’s reaction to stress. The adrenal glands-small glands located above both kidneys-are composed of two separate regions: the medulla and the cortex.
