It consists of a hormone - producing glandular portion (anterior pituitary) and a neural portion (posterior pituitary), which is an extension of the hypothalamus . The hypothalamus regulates the hormonal output of the anterior pituitary and creates two hormones that it exports to the posterior pituitary for storage and later release . </P> <P> Four of the six anterior pituitary hormones are tropic hormones that regulate the function of other endocrine organs . Most anterior pituitary hormones exhibit a diurnal rhythm of release, which is subject to modification by stimuli influencing the hypothalamus . </P>

A hormone produced by the pituitary and regulates the function of another endocrine gland is called
