/ pɪˈtu ɪˌtɛr i ˌglænd, pɪˈtyu‐ /

noun Anatomy.

a small, somewhat cherry-shaped double structure attached by a stalk to the base of the brain and constituting the master endocrine gland affecting all hormonal functions in the body, consisting of an anterior region (anterior pituitary, oradenohypophysis ) that develops embryonically from the roof of the mouth and that secretes growth hormone, LH, FSH, ACTH, TSH, and MSH, a posterior region (posterior pituitary, orneurohypophysis ) that develops from the back of the forebrain and that secretes the hormones vasopressin and oxytocin, and an intermediate part (pars intermedia ), derived from the anterior region but joined to the posterior region, that secretes the hormone MSH in lower vertebrates.

Also called hypophysis.

Scientific definitions for pituitary gland

pituitary gland

[ pĭ-tōō′ĭ-tĕr′ē ]

A gland at the base of the brain in vertebrate animals that is divided into two regions, anterior and posterior, each of which secretes important hormones. The anterior portion, whose secretions are directly controlled by the hypothalamus, produces hormones that regulate the function of most of the body's hormone-producing glands and organs, including the thyroid and adrenal glands. Growth hormone is also produced by the anterior pituitary. The posterior pituitary releases antidiuretic hormone (ADH) and oxytocin.
