Pituitary Gland
The Pituitary gland is a pea-sized gland located at the base of the skull. This gland secretes hormones. It is sometimes referred to as the “master gland” because it controls hormone functions such as our temperature, our growth during childhood, urine production, testosterone production in males and ovulation in females. You could compare this gland to a thermostat. It controls all of the other glands that are responsible for our hormone secretion. Other examples would be that this gland determines how fast you will grow and how tall or short you may be.

The pituitary gland functions as two other compartments, one which is known as the anterior portion and the posterior gland. The anterior portion is made of a separate collection of cells that act as functional units that are dedicated to produce a specific regulatory hormone messenger.

The red dot would be the pituitary gland; this picture can show you how small this gland is compared to the brain.
