hormones secreted by the three cell layers of the adrenal cotrex
cretinism
dwarfism caused by hyposecretion of the thyroid gland
Cushing's syndrome
condition caused by the hypersecretion
diabetes insipidus
condition resulting from hyposecretion of ADH in which large volumes of urine are formed and, if left untreated may cause serious health problems
diabetes mellitus
a condition resulting when the pancreatic islets secrete too little insulin, resulting in increased levels of blood glucose
gigantism
a condition produced by hypersecretion of growth hormone during the early years of life; results in a child who grows to gigantic size
glucocorticoids
hormones that influence food metabolism; secreted by the adrenal cortex
gluconeogenisis
formulation of glucose or glycogen from protein or fat compounds
glycogenolysis
formation of glycogen from glucose or from other monosaccharides, fructose, or galactose
glycosuria
glucose in the urine, a sign of diabetes mellitus
goiter
enlargement of the thyroid gland
hormone
substance secreted by an endocrine gland
hypercalcemia
a condition in which there is harmful excess of calcium in the blood
hyperglycemia
higher than normal blood glucose concentration
hypoglycemia
lower-than-normal blood glucose concentration
luteinization
the formation of a golden body (corpus lutenum) in the ruptured follicle
mineralocorticoids
hormone that influences mineral salt metabolsim; secreted by adrenal cortex; aldosterone is the chief mineralocorticoid
myxedema
condition caused by deficency of thyroid hormone in adults
negative feedback
homeostatic control system in which information feeding back to the control center causes the level of a variable to be changed in the direction opposite to that of the initial stimulus
nonsteroid hormone
general type of hormone that does have the lipid steroid structure but is instead a protein or protein derivative; also sometimes called protein hormone
prostaglandins
a group of naturally occuring fatty acids that affect many body functions
second messanger
chemical that provides communication within a hormone's target cell
steroid hormone
lipid-soluble hormones that pass intact through the cell membrane of the target cell and influence cell activity by acting on specific genes
stress
extreme stimuli act on the body which produces an internal state called stress
target cell
cell acted on by a particular hormone and responding to it
