gland that produces hormones that help control calcium levels and maintain a normal metabolism
hormone produced in the thyroid that helps regulate metabolism (i.e., T4)
hormone produced in the thyroid that helps regulate metabolism (i.e., T3)
hormone secreted by the thyroid when calcium levels are high in order to stimulate calcium to leave the blood and enter the bones
parathyroid glands
glands that produce hormones that regulate calcium levels in the blood
parathyroid hormone
hormone secreted by the parathyroid glands that mobilizes calcium from the bones into the bloodstream when calcium levels are low
equilibrium or constancy in the internal environment
adrenal glands
glands that secrete corticosteroids and catecholamine hormones
adrenal cortex
part of the adrenal gland that secretes corticosteroids
adrenal medulla
part of the adrenal gland that secretes catecholamine
complex chemicals derived from cholesterol
chemicals derived from amino acids
corticosteroids that have an important influence on the metabolism of sugars, fats, and proteins and have a powerful anti-inflammatory effect
hormone that helps regulate glucose, fat, and protein metabolism; raises blood glucose as part of a response to stress
hormone useful in treating inflammatory conditions
aldosterone is this type of hormone
hormone that regulates blood volume, blood pressure and electrolyte concentration by regulating the concentration of salts and helping the kidney reabsorb sodium and water
sex hormones
Produced in the adrenal cortex, androgens and estrogens are THESE types of hormones.
hormone that increases the heart rate and blood pressure, dilates bronchial tubes, and releases glucose from glycogen when body needs it for more energy
hormone that constricts blood vessels to raise blood pressure
sympathomimetic agents
hormones that mimic, or copy, the actions of the sympathetic nervous system
endocrine and exocrine gland that secretes insulin and digestive enzymes
islets of Langerhans
the endocrine tissue of the pancreas producing insulin and glucagon
hormone that lowers high-levels of blood sugar by helping it enter the body cells; also lowers blood sugar by causing the conversion of glucose to glycogen
hormone that raises low-levels of blood sugar by acting on liver cells to promote conversion of glycogen back to glucose

gland located at the base of the brain that regulates growth hormones and make hormones that controls several other glands
other name for the pituitary gland
the anterior lobe of the pituitary
the posterior lobe of the pituitary

hormone that stimulates protein synthesis that results in growth of bones, muscles and other tissues
other name for growth hormone
thyroid-stimulating hormone
hormone that stimulates the growth of the thyroid gland and secretion of thyroid hormones
other name for thyroid-stimulating hormone
adrenocorticotropic hormone
hormone that stimulates the growth of the adrenal cortex and increases its secretion of steroid hormones
other name for adrenocorticotropic hormone
