What is the pituitary gland?
The pituitary gland is a small organ found at the base of the brain. It is called the "master gland" because it controls all of the other glands in the body.
The pituitary gland makes many different hormones. Hormones are chemical messengers that turn on and off different processes in the body. Here is a list of some of the hormones made by the pituitary gland and an explanation of what those hormones do:
- Corticotropin (also called "ACTH") – Corticotropin tells the adrenal glands to release a hormone called cortisol. Cortisol helps control how the body uses sugar
- Thyroid-stimulating hormone (called "TSH") – TSH tells the thyroid gland to release hormones called "T3" and "T4." These hormones control how the body uses and stores energy.
- Gonadotropins – In females, gonadotropins tell the ovaries to release the hormones estrogen and progesterone. They also tell the ovaries to prepare and release eggs. In males, these hormones tell the testicles to make testosterone and sperm.
- Growth hormone – Growth hormone helps children grow to a normal height. In adults, it helps keep the right balance of fat and muscle in the body.
- Prolactin – Prolactin helps control the development of breasts. It also tells the breasts to make milk after giving birth.
