Where is the pituitary gland located?

The pituitary gland is located at the base of the brain, just below the hypothalamus. It rests in a protective bone chamber called the sella turcica within the sphenoid bone. Though only about the size of a pea, the pituitary is often called the body's master gland because it releases hormones that influence growth, metabolism, reproduction, and stress response. It has an anterior and posterior lobe, each with different functions. Because of its central role, even small tumors or injuries affecting the pituitary can have major effects on health.
