Abstract

Release of anterior pituitary hormones is mediated by peptides produced by secretory neurons in the hypothalamus or preoptic area. The releasing or inhibiting factors are stored in nerve endings that lie in the median eminence and are secreted as the result of electrical activity. The hypothalamic peptides then travel through the portal system to the anterior pituitary where they interact with specific surface receptors to trigger release of pituitary trophic hormones. These, in turn, regulate physiologic processes elsewhere in the body either directly or indirectly through release of target gland hormones.
