THE PITUITARY GLAND

The pituitary is called the master gland because it releases many hormones that reach other glands and stimulate them to secrete their own hormones. The anterior pituitary therefore has many target organs. The pituitary has two parts: the anterior pituitary and the posterior pituitary. Each part secretes its own set of hormones.

The anterior pituitary secretes six hormones, three of which regulate growth and other organs. The other three are involved in regulating the reproductive systems. The hormones of the pituitary are:

Growth hormone (GH)—stimulates growth throughout the body, targets bones and muscles

Adrenocorticotropic hormone (ACTH)—stimulates the adrenal cortex to secrete glucocorticoids and mineralocorticoids

Thyroid-stimulating hormone (TSH)—stimulates the thyroid to secrete thyroxine

Follicle-stimulating hormone (FSH)—stimulates the follicle to grow in females, and spermatogenesis in males

Luteinizing hormone (LH)—causes the release of the ovum during the menstrual cycle in females, and testosterone production in males

Prolactin—stimulates the mammary glands to produce milk
