The pituitary gland, or hypophysis, is an endocrine gland about the size of a pea that sits in the small, bony cavity (sella turcica) at the base of the brain.
The pituitary gland secretes hormones regulating a wide variety of bodily activities, including trophic hormones that stimulate other endocrine glands. For a while, this led scientists to call it the master gland, but now we know that it is in fact regulated by hormones released from the hypothalamus.
The pituitary gland is physically attached to the brain by the pituitary, or hypophyseal stalk connected with the median eminence.
