adrenaline
Produced by the adrenal medulla; also called epinephrine; increases heart rate and blood pressure.
adrenocorticotropic hormone (ACTH)
Produced by the anterior lobe of the pituitary gland (adenohypophysis); also called adrenocorticotropin; stimulates adrenal cortex.
aldosterone
Produced by the adrenal cortex; increases salt (sodium) reabsorption.
androgen
Male hormone produced by the testes and to a lesser extent by the adrenal cortex. Testosterone is an example. Maintains secondary sex characteristics.
antidiuretic hormone (ADH)
Secreted by the posterior lobe of the pituitary gland (neurohypophysis); increases reabsorption of water by the kidney tubules and is also known as vasopressin.
calcitonin
Produced by the thyroid gland; lowers blood calcium; also called thyrocalcitonin.
cortisol
Produced by the adrenal cortex; increases blood sugar.
epinephrine
Produced by the adrenal medulla; also called adrenaline; a sympathomimetic that increases heart rate and blood pressure and dilates airways.
estradiol
An estrogen (female hormone) produced by the ovaries that develops and maintains secondary sex characteristics.
estrogen
Female hormone produced by the ovaries and to a lesser extent by the adrenal cortex; maintains secondary sex characteristics.
follicle-stimulating hormone (FSH)
Produced by the anterior lobe of the pituitary gland (adenohypophysis); stimulates hormone secretion and egg production by the ovaries and sperm production by the testes.
glucagon
Produced by the islet cells of the pancreas; increases blood sugar by conversion of glycogen (starch) to glucose.
growth hormone (GH)
Produced by the anterior lobe of the pituitary gland (adenohypophysis); also called somatotropin; stimulates the growth of bones and tissues.
insulin
Produced by the islet cells of the pancreas; lowers blood sugar by transport and conversion of glucose to glycogen (starch).
luteinizing hormone (LH)
Produced by the anterior lobe of the pituitary gland (adenohypophysis); stimulates ovulation in females. As interstitial cell-stimulating hormone (ICSH) in males, it stimulates testosterone secretion.
melanocyte-stimulating hormone (MSH)
Produced by the anterior lobe of the pituitary gland (adenohypophysis); high levels increase the pigmentation of the skin.
norepinephrine
Produced by the adrenal medulla; also called noradrenaline; a sympathomimetic that increases heart rate and blood pressure.
oxytocin
Secreted by the posterior lobe of the pituitary gland (neurohypophysis); stimulates contraction of the uterus during labor and childbirth.
parathormone (PTH)
Produced by the parathyroid gland; also called parathyroid hormone; increases blood calcium.
progesterone
Produced by the ovaries; prepares the uterus for pregnancy.
prolactin (PRL)
Produced by the anterior lobe of the pituitary gland (adenohypophysis); promotes growth of breast tissue and milk secretion.
somatotropin
Produced by the anterior lobe of the pituitary gland (adenohypophysis); also called growth hormone (GH); increases bone and tissue growth.
testosterone
Male hormone produced by the testes; promotes growth and maintenance of secondary sex characteristics in males.
thyroid-stimulating hormone (TSH)
Produced by the anterior lobe of the pituitary gland (adenohypophysis); acts on the thyroid gland to promote its functioning; stimulates production of thyroxine and the growth of the thyroid gland; also called thyrotropin.
thyroxine (tetraiodothyronine; T4)
Produced by the thyroid gland; increases metabolism in body cells
triiodothyronine (T3)
Produced by the thyroid gland; increases metabolism in cells.
vasopressin
Secreted by the posterior lobe of the pituitary gland (neurohypophysis); also called antidiuretic hormone (ADH); stimulates reabsorption of water by kidney tubules.
