Pituitary Hormone-Releasing Hormones

Medical Definition:	Hormones released by one structure (e.g., the hypothalamus or the thyroid gland) that effect the secretion of hormones from the pituitary gland.
Guide Notes:	IM + coord with specific hormone (IM) but note many specific precoords available; /biosyn /drug eff /physiol permitted; DF: PHRH
Also Called:	Hypothalamic Releasing Factor
Previously Indexed:	Hypothalamo-Hypophyseal System/physiology (1966-1967)

Pituitary Hormone-Releasing Hormones Categories.

	Corticotropin-Releasing Hormone - A neuropeptide released by the hypothalamus that stimulates the release of corticotropin by the anterior pituitary gland.
	Gonadorelin - A decapeptide hormone released by the hypothalamus. It stimulates the synthesis and secretion of both FOLLICLE STIMULATING HORMONE and luteinizing hormone (LH) from the pituitary gland.
	MSH-Releasing Hormone - A polypeptide hormone which originates in the hypothalamus and stimulates secretion of melanocyte-stimulating hormones in the pituitary gland.
	Prolactin-Releasing Hormone - A polypeptide hormone that originates in the hypothalamus and stimulates the secretion of prolactin in the pituitary gland.
	Protirelin - A tripeptide hormone that originates in the hypothalamus and stimulates the secretion of thyrotropin from the pituitary gland. In humans, it also acts as a prolactin-releasing factor. It is also a neurotransmitter in the central nervous system.
	Somatotropin-Releasing Hormone - Hypothalamic peptide that regulates the synthesis and secretion of GROWTH HORMONE in the anterior pituitary gland.
