Hormone functions Flashcards
Growth Hormone Releasing Hormone (GHRH)
promotes release of hGH
Growth Hormone Inhibiting Hormone (GHIH)
Inhibits release of hGH
Thyrotropin Releasing Hormone (TRH)
controls TSH secretion
Gonadotropin Releasing Hormone (GnRH)
stimulates FSH release
Prolactin Releasing Hormone (PRH)
Increases or stimulates prolactin
Prolacting Inhibiting Hormone (PIH)
inhibits release of PRL & MSH
Corticotropin Releasing Hormone (CRH)
stimulates secretion of ACTH & MSH by corticotrophs
Human Growth Hormone (hGH)
stimulates general body growth and regulates aspects of metabolism
Thyroid Stimulating Hormone (TSH)
stimulates synthesis of T3 and T4
Follicle Stimulating Hormone (FSH)
Initiates the development of several ovarian follicles, saclike arrangements of secretory cell that surround a developing oocyte, sperm production
Luteinizing Hormone (LH)
triggers ovulations, estrogen, test.
Prolactin (PRL)
Initiates and maintains milk production by the mammary glands
Adrenocorticotropic Hormone (ACTH)
Influences the production and secretion of certain hormones of the adrenal cortex
Melanocyte Stimulating Hormone (MSH)
darkens the skin
Antidiuretic Hormone (ADH)
decreases urine production
Oxytocin (OT)
stimulates uterine contractions during child birth, contraction of mammary glands to cause milk ejection
Triiodothryronine (T3) and Thyroxine (T4)
increase basal metabolic rate, stimulate synthesis of proteins; increase use of glucose and fatty acids for ATP production; increase dypolysis; enhance cholesterol excretion, accelerates body growth, development of nervous systems
Calcitonin (CT)
Lowers the amount of blood calcium and phosphates by inhibiting bone resorption and accelerates the uptake of calcium and phosphates in the blood matrix
Parathyroid Hormone (PTH)
regulates the levels of calcium, magnesium and phosphate in the blood
Aldosterone
promotes sodium reabsorption by the kidneys and potassium excretion in urine
Cortisol
regulates metabolism and resistance to stress, protein breakdown and immune response
Dehydroepiandrosterone (DHEA)
In females, promotes libido and are converted into estrogen
Epinephrine and Norepinephrine (NE)
augment fight-or-flight response
Glucagon
increase blood glucose level when it falls below normal
insulin
lowers blood glucose level by accelerating transport of glucose into cells
somatostatin
inhibits secretion of insulin and glucagon
Pancreatic Polypeptide
inhibits somatostatin secretion, gallbladder contraction and secretion of pancreatic digestive enzymes
Estrogens and Progesterone
regulate female reporductive cycle, maintain pregnancy, prepare mammary glands for lactation
relaxin
Increases flexibility of pubic symphysis during pregnancy
inhibin
Inhibits secretion of FSH from anterior pituitary
Testosterone
stimulates descent of testes before birth, regulates spermatogenesis
