Terms in this set (33)
Growth Hormone Releasing Hormone (GHRH)
Stimulates secretion of growth hormone (hGH)
Growth Hormone Inhibiting Hormone (GHIH)
Inhibits secretion of growth hormone (hGH) AND Inhibits secretion of thyroid stimulating hormone (TSH)
Thyrotropin Releasing Hormone (TRH)
Stimulates secretion of thyroid stimulating hormone (TSH)
Gonadotropin Releasing Hormone (GnRH)
Stimulates secretion of follicle stimulating hormone (FSH) and luteinizing hormone (LH)
Prolactin Releasing Hormone (PRH)
Simulates secretion of prolactin (PRL)
Prolactin Inhibiting Hormone (Dopamine; PIH)
Inhibits secetion of prolactin (PRL)
Corticotropin Releasing Hormone (CRH)
Stimulates secretion of adrenocorticotropic hormone (ACTH)
Human Growth Hormone (hGH)
Promotes secretion of insulin-like growth factors (IGFs) which act widespread or locally to increase cell growth and multiplication by promoting protein synthesis. Increases growth of skeleton and skeletal muscles and promotes tissue repair.
Thyroid Stimulating Hormone (TSH)
Release of T3 and T4 from thyroid gland
Follicle Stimulating Hormone (FSH)
Luteinizing Hormone (LH)
In females it stimulates ovulation and formation of corpus luteum in ovary (which produces progesterone) also stimulates estrogen production in secondary and mature follicles. In males it stimulates testosterone secretion from testes.
Adrenocorticotropic Hormone (ACTH)
Stimulates release of cortisol from zona fasciculata
Melanocyte Stimulating Hormone (MSH)
Melanocytes of skin darken skin color.
Stimulates uterine contractions during labor and stimulates milk ejection (females)Parental behavior and pair bonding between mates AND In males contraction of ductus deferens and prostate during orgasm
Antidiuretic Hormone (ADH)
Causes increased water reabsorption in kidney (reduces urine output), decreases water loss from sweat glands, constricts arterioles to increase blood pressure.
Thyroid Hormones (T3 and T4)
Increased metabolic rate, heat production (due to increased Na+-K+-pumps and Na+-K+-pump activity. Increased lipolysis and cholesterol excretion. Increased use of glucose. Increased protein synthesis.
Lowers blood calcium concentration by inhibiting osteoclast activity and promoting calcium and phosphate uptake into bone.
Increases bone reabsorption by osteoclasts (i.e., osteoclast activity increases releasing calcium from the bone matrix); stimulates the kidney to reabsorb more calcium preventing calcium loss in the urine; promotes the synthesis of calcitriol in the kidney; calcitriol stimulates increased absorption of calcium from food stuff in the digestive tract.
Promotes increased sodium reabsorption and potassium excretion.
Enhances the sympathetic nervous system response. Increased heart rate, dilation of arterioles supplying the heart, skeletal muscle, and liver. Dilation of airways. Breakdown of glycogen to glucose into the liver to increase blood glucose levels.
Promotes the transport of glucose into muscle and liver cells. Stimulates glycogen formation in the liver and skeletal muscle (glycogenesis). Increases uptake of amino acids into these tissues. Promotes lipogenesis (formation of fats) in adipose. Inhibits glycogen breakdown (glycogenolysis) and gluconeogenesis.
Promotes glycogenolysis and gluconeogenesis to increase blood glucose levels.
Descent of the testes before birth, sperm production in testes, secondary sex characteristics (pubic and axillary hair, deepening of voice, growth of skeletal muscles, growth of bone, pattern baldness, etc.) development of sex organs.
Regulates and coordinates uterine and ovarian cycles, secondary sex characteristics of females, and development of endometrium, prepares mammary glands for lactation. Distributes fat to the hips and breast.
Atrial Natriuretic Peptide (or factor) ANP or ANF
Arterioles: vasodilation, this decreases blood pressure and increases blood flow to the kidneys allowing more blood to be filtered.
Stimulates secretion of pancreatic enzymes and bicarbonate solution from pancreas; stimulates gall bladder to release bile; maintains pancreas and enhances the effect of cholecystokinin.
Inhibits neuronal circuits that are involved in feeding (makes us feel satiated) and stimulates neuronal circuits that promote energy expenditure.
In the digestive tract,stimulates pancreatic secretion and contraction of the gall bladder.
Stimulates production of red blood cell precursors (increases numbers of red blood cells)
Human Chorionic Gonadotropin
Causes the ovary to continue to produce progesterone and estrogen that maintain the integrity of the endometrium throughout pregnancy.
Stimulates release of pepsinogen from chief cells and HCl from parietal cells. Also stimulates the release of intrinsic factor from parietal cells.
Skeletal muscle: protein breakdown. Release of amino acids from skeletal muscle occurs under extreme stress and starvation.
