Definition: A small, oval-shaped gland located at the base of the brain; part of the endocrine system
The pituitary gland has two lobes called the anterior pituitary and the posterior pituitary glands. Often called the master gland, the pituitary gland releases hormones that cause other endocrine system glands to function normally.
In women, the pituitary gland triggers ovulation by producing follicle-stimulating hormone (FSH) and luteinizing hormone (LH), which cause the ovaries to produce estrogen and progesterone. The pituitary gland also controls the release of hormones in the male testes, as well as hormonal activities involved in metabolism and growth.
Also Known As: master gland
