In vertebrate anatomy, the pituitary gland, or hypophysis, is an endocrine gland aboot the size o a pea an weighin 0.5 grams (0.018 oz) in humans. It is a protrusion off the bottom o the hypothalamus at the base o the brain. The hypophysis rests upon the hypophysial fossa o the sphenoid bane in the center o the middle cranial fossa an is surroondit by a smaa bany cavity (sella turcica) covered bi a dural fold (diaphragma sellae). The anterior pituitary (or adenohypophysis) is a lobe o the gland that regulates several pheesiological processes (includin stress, growth, reproduction, an lactation).
