ADENOHYPOPHYSIAL HORMONES DIRECT ACTIONS Growth hormone releasing hormone (GHRH) ===> somatotrophin (GH) ===> somatic tissues GH release inhibited by somatostatin - promotes growth by stimulating proteins synthesis of virtually all tissues sensory input ===> prolactin prolactin release inhibited by prolactin inhibiting factor (PIF) - stimulates milk production MSH releasing factor ===> melanocyte-stimulating hormone (MSH; also released in response to corticotrophin releasing factor; CRF) - stimulates melanin synthesis in melanocytes INDIRECT ACTIONS Thyrotrophin releasing factor (TRF or TRH) ===> thyrotrophin or thyroid stimulating hormone (TSH) ===> thyroid gland ===> thyroxine ===> tissues - regulates development - regulates metabolic rate in adulthood Corticotrophin releasing factor (CRF) ===> corticotrophin or adrenocorticotrophic hormone

Unformatted text preview: (ACTH) ===> cortisol, aldosterone- cortisol in inhibits protein synthesis, stimulates gluconeogenesis (synthesis of glucose from proteins), inhibits conversion of carbohydrates to fats- aldosterone regulates electrolytes, especially sodium Gonadotrophin releasing hormone (GnRH) or leuteinizing hormone releasing hormone (LHRH) ===> luteinizing hormone (LH) and follicle stimulating hormone (FSH) ===> gonads ===> androgens or estrogens and progesterone- sexual differentiation during development- LH and FSH also stimulate gametogenesis and, in females, ovulation NEUROHYPOPHYSIAL HORMONES stimulation of cervix, nipples ===> oxytocin- "turns on" maternal behavior- stimulates mammary glands, causing milk ejection low blood pressure ===> vasopressin or antidiuretic hormone (ADH)- causes kidneys to retain more water...
