Feedback mechanisms in the hormone secretions of the hypothalamo-pituitary-adrenal axis. Solid line = stimulation of secretion; dashed line = negative feedback. ACTH = adrenocorticotropic hormone; CRH = corticotropin-releasing hormone; FSH = follicle-stimulating hormone; GH = growth hormone; GHRH = growth hormone-releasing hormone; GnRH = gonadotropin-releasing hormone; LH = luteinizing hormone; PRF = prolactin-releasing factor; PRL = prolactin; TRH = thyrotropin-releasing hormone; TSH = thyroid-stimulating hormone. © 2016 British Small Animal Veterinary Association
