To better understand pheochromocytoma, it helps to understand the anatomy of the adrenal glands.
The adrenal glands are paired triangular shaped endocrine glands located at the upper portion of each kidney.
This gland is composed of adrenal cortex and the adrenal medulla. Hormones that regulate the balance of salt, fluids and other body functions are produced by the adrenal cortex and medulla.
