internal secretion

a hormone produced by the anterior pituitary gland that stimulates the adrenal cortex

a catecholamine secreted by the adrenal medulla in response to stress (trade name Adrenalin); stimulates autonomic nerve action

hormones that affect gastrointestinal functioning

a hormone secreted by the pancreas; stimulates increases in blood sugar levels in the blood (thus opposing the action of insulin)

hormone secreted by the anterior pituitary gland and placenta; stimulates the gonads and controls reproductive activity

hormone secreted by the isles of Langerhans in the pancreas; regulates storage of glycogen in the liver and accelerates oxidation of sugar in cells

hormone secreted by the pineal gland

a hormone that is released by nerve impulses (e.g., norepinephrine or vasopressin)

hormone secreted by the posterior pituitary gland (trade name Pitocin); stimulates contractions of the uterus and ejection of milk

hormone synthesized and released into the blood stream by the parathyroid glands; regulates phosphorus and calcium in the body and functions in neuromuscular excitation and blood clotting

hormone secreted by the corpus luteum during the last days of pregnancy; relaxes the pelvic ligaments and prepares the uterus for labor

any of several hormones produced in the hypothalamus and carried by a vein to the anterior pituitary gland where they stimulate the release of anterior pituitary hormones; each of these hormones causes the anterior pituitary to secrete a specific hormone

a hormone produced by the anterior pituitary gland; promotes growth in humans

hormone secreted by the thymus; stimulates immunological activity of lymphoid tissue

any of several closely related compounds that are produced by the thyroid gland and are active metabolically

hormone secreted by the posterior pituitary gland (trade name Pitressin) and also by nerve endings in the hypothalamus; affects blood pressure by stimulating capillary muscles and reduces urine flow by affecting reabsorption of water by kidney tubules

any hormone affecting the development and growth of sex organs

a steroid having androgenic activity; obtained from the cortex of the adrenal gland

a steroid hormone that is produced by the adrenal cortex of animals; affects functioning of gonads and has anti-inflammatory activity

any of a group of chemicals including epinephrine and norepinephrine that are produced in the medulla of the adrenal gland

a hormone secreted by the anterior pituitary gland that controls the degree of pigmentation in melanocytes

anterior pituitary hormone that stimulates the function of the thyroid gland

hormone released by the hypothalamus that controls the release of thyroid-stimulating hormone from the anterior pituitary

a catecholamine precursor of epinephrine that is secreted by the adrenal medulla and also released at synapses

polypeptide hormone secreted by the mucous lining of the stomach; when peptides and amino acids are present in the small intestine the secretion of gastric acid is stimulated

a gastrointestinal hormone that stimulates the secretion of pancreatic enzymes and the contraction and emptying of the gall bladder; its release is stimulated by the presence of fatty acids and amino acids in the small intestine

a gastrointestinal hormone that stimulates the secretion of water and bicarbonate from the pancreas and bile ducts whenever the stomach empties too much acid into the small intestine

a gastrointestinal hormone produced by epithelial cells lining the fundus of the stomach; appears to be a stimulant for appetite and feeding, but is also a strong stimulant of growth hormone secretion from the anterior pituitary

a gastrointestinal hormone that apparently participates in controlling smooth muscle contractions in the stomach and small intestine

trade names for forms of insulin that are used to treat diabetes mellitus

a form of insulin (trade name Humulin) made from recombinant DNA that is identical to human insulin; used to treat diabetics who are allergic to preparations made from beef or pork insulin

trade name of a synthetic human growth hormone given to children deficient in the hormone; use by athletes and weightlifters is banned

thyroid hormone that tends to lower the level of calcium in the blood plasma and inhibit resorption of bone

hormone produced by the thyroid glands to regulate metabolism by controlling the rate of oxidation in cells

thyroid hormone similar to thyroxine but with one less iodine atom per molecule and produced in smaller quantity; exerts the same biological effects as thyroxine but is more potent and briefer

secreted by the adrenal cortex; involved in regulating water and electrolyte balance in the body

any of a group of steroid hormones that have the effect of progesterone

male sex hormone that is produced in the testes and responsible for typical male sexual characteristics

a gonadotropic hormone that is secreted by the anterior pituitary and stimulates growth of Graafian follicles in female mammals, and activates the cells in male mammals that form sperm

hormone produced early in pregnancy by the placenta; detection in the urine and serum is the basis for one kind of pregnancy test

a gonadotropic hormone that is secreted by the anterior pituitary; stimulates ovulation in female mammals and stimulates androgen release in male mammals

gonadotropic hormone secreted by the anterior pituitary; in females it stimulates growth of the mammary glands and lactation after parturition

a general term for female steroid sex hormones that are secreted by the ovary and responsible for typical female sexual characteristics

a steroid hormone produced by the adrenal cortex or synthesized; administered as drugs they reduce swelling and decrease the body's immune response

a glucocorticoid (trade names Pediapred or Prelone) used to treat inflammatory conditions

a dehydrogenated analogue of cortisol (trade names Orasone or Deltasone or Liquid Pred or Meticorten); used as an anti-inflammatory drug in the treatment of arthritis and as an immunosuppressant

any of a group of synthetic steroid hormones used to stimulate muscle and bone growth; more than 100 have been developed and each requires a prescription to be used legally in the United States; sometimes used illicitly by athletes to increase their strength
