A small oval endocrine gland attached to the base of the vertebrate brain and consisting of an anterior and a posterior lobe, the secretions of which control the other endocrine glands and influence growth, metabolism, and maturation. Also called hypophysis, pituitary body.

pituitary gland

or

pituitary body

n
(Anatomy) the master endocrine gland, attached by a stalk to the base of the brain. Its two lobes (the adenohypophysis and neurohypophysis) secrete hormones affecting skeletal growth, development of the sex glands, and the functioning of the other endocrine glands. Also called: hypophysis or hypophysis cerebri See also adenohypophysis, neurohypophysis

pitu′itary gland`


n.
a small, somewhat cherry-shaped double-lobed structure attached to the base of the brain, constituting the master endocrine gland affecting all hormonal functions of the body. Compare anterior pituitary, posterior pituitary.

pi·tu·i·tar·y gland

(pĭ-to͞o′ĭ-tĕr′ē)
A gland at the base of the brain in vertebrate animals that regulates the function of most of the body's hormone-producing glands and organs, including the thyroid and adrenal glands. The pituitary gland also controls overall body growth.

Most patients require life-long replacement with anterior pituitary hormones, since surgery has no significant effect on improving the preexisting endocrine defects(12,13).
Examples are: insulin from the pancreas, cortisol and adrenaline from the adrenal glands, oestrogen and progesterone from the ovaries, pituitary hormones from the pituitary glands, thyroid hormones from the thyroid gland and testosterone from the testicles.
