In [http://en.wikipedia.org/wiki/Vertebrate vertebrate] [http://en.wikipedia.org/wiki/Anatomy anatomy] the '''pituitary gland''', or hypophysis, is an [http://en.wikipedia.org/wiki/Endocrine_gland endocrine gland] about the size of a pea and weighing 0.5 g (0.02 oz.). It is a protrusion off the bottom of the [http://en.wikipedia.org/wiki/Hypothalamus hypothalamus] at the base of the [[brain]], and rests in a small, bony cavity ([http://en.wikipedia.org/wiki/Sella_turcica sella turcica]) covered by a [http://en.wikipedia.org/wiki/Dura_mater dural]  fold ([http://en.wikipedia.org/wiki/Diaphragma_sellae diaphragma sellae]). The pituitary fossa, in which the pituitary gland sits, is situated in the [http://en.wikipedia.org/wiki/Sphenoid sphenoid] bone in the middle [http://en.wikipedia.org/wiki/Middle_cranial_fossa cranial fossa] at the base of the [[brain]]. It is [[considered]] a master gland. The pituitary gland secretes [http://en.wikipedia.org/wiki/Hormone hormones] regulating [http://en.wikipedia.org/wiki/Homeostasis homeostasis], including [http://en.wikipedia.org/wiki/Tropic_hormone tropic hormones] that stimulate other [http://en.wikipedia.org/wiki/Endocrine_glands endocrine glands]. It is [[functionally]] [[connected]] to the [http://en.wikipedia.org/wiki/Hypothalamus hypothalamus]  by the median eminence.

The pituitary is [[composed]] of [[two]] lobes: the ''anterior pituitary'' (adenohypophysis) and the ''posterior pituitary'' (neurohypophysis). The pituitary is [[functionally]] linked to the hypothalamus by the [http://en.wikipedia.org/wiki/Pituitary_stalk pituitary stalk], whereby hypothalamic releasing factors are released and, in turn, stimulate the release of pituitary hormones. Although the pituitary gland is known as the master endocrine gland, both of its lobes are under the [[control]] of the [http://en.wikipedia.org/wiki/Hypothalamus hypothalamus]. If there are [[problems]] with the pituitary gland, it can cause an irregular condition know as [http://en.wikipedia.org/wiki/Gigantism gigantism].[http://en.wikipedia.org/wiki/Pituitary_gland]
