7. What is the Pituitary Gland?

The pituitary gland is the "master gland" -- it is quite small but has a big job. It is located at the brain’s base and is roughly the size of a pea. The pituitary gland secretes hormones that control other glands within the endocrine system. It makes growth hormone, prolactin (involved in milk production), hormones that stimulate the thyroid, and even hormones that control the amount of fluid in the body. It also receives messages from the hypothalamus, which drives this system and links it with the nervous system.
