Explanation
Understanding the full names of hormones often reveals their primary function, origin, or chemical structure, making it easier to connect them to their abbreviations.
The hypothalamic hormones, GnRH and CRH, are “releasing hormones.” Gonadotropin-Releasing Hormone (GnRH) stimulates the pituitary to release gonadotropins (hormones affecting the gonads), namely FSH and LH. Similarly, Corticotropin-Releasing Hormone (CRH) causes the release of corticotropin, also known as ACTH.
The anterior pituitary produces several “tropic” hormones that stimulate other endocrine glands. Thyroid-Stimulating Hormone (TSH) directly targets and stimulates the thyroid gland. Adrenocorticotropic Hormone (ACTH) acts on the cortex of the adrenal gland. The other pituitary gonadotropins have names describing their specific roles. Follicle-Stimulating Hormone (FSH) is essential for gamete production, stimulating follicle growth in females and sperm production in males. Luteinizing Hormone (LH) is named for its role in converting the ovarian follicle into the corpus luteum after ovulation. Prolactin (PRL) literally means “promoting lactation,” highlighting its function in milk production.
Other hormones are named for their location or composition. Parathyroid Hormone (PTH) comes from the parathyroid glands, which are located posterior to, or “near,” the thyroid. The thyroid hormone T3, or triiodothyronine, is named for the three iodine atoms in its structure. Antidiuretic Hormone (ADH), released from the posterior pituitary, means “against urine” because it reduces urine output by increasing water reabsorption. Lastly, Atrial Natriuretic Peptide (ANP) is a peptide (amino acid-based) hormone produced by the atria of the heart that helps regulate blood pressure.
