| Term | Definition |
| corticoids | hormones secreted by the three cell layers of the adrenal cortex |
| cretenism | dwarfism caused by hyposecretion of the thyroid gland |
| diabetes insipidus | Excessive urination and extreme thirst as a result of inadequate output of the pituitary hormone ADH (antidiuretic hormone, also called vasopressin) or the lack of the normal response by the kidney to ADH. |
| diabetes mellitus | a condition resulting when the pancreatic islets secrete too little insulin, resulting in hyperglycemia |
| gigantism | excessive growth both in height and specific body parts |
| glucocorticoids | hormones that influence food metabolism; secreted by the adrenal glands |
| gluconeogenesis | formation of glucose from proteins and fats |
| glycogenolysis | the breakdown of glycogen especially to glucose |
| glycosuria | the presence in the urine of abnormal amounts of sugar |
| goiter | enlargement of the thyroid gland |
| hormone | substance secreted by and endocrine gland |
| hypercalcemia | an excess of calcium in the blood |
| hyperglycemia | an excess of sugar in the blood |
| hypoglycemia | abnormal decrease of sugar in the blood |
| mineralocorticoids | a corticosteroid (as aldosterone) that affects chiefly the electrolyte and fluid balance in the body |
| melatonin | hormone that regulates body's internal clock |
| hormone secretion is regulated by | negative and positive feedback loops |
| adenohypophysis | the anterior pituitary lobe |
| TSH | is secreted by adenohypophysis; stimulates the release of thyroid hormone |
| FSH | stimulates the primary ovarian follicle to develop |
| Neurohypophysis | posterior lobe of the pituitary gland |
| neurohypophysis releases | ADH and oxytocin |
| Oxytocin | stimulates uterine contraction, uses a positive feedback mechanism |
| Thyroid gland secretes | T3, T4, Calcitonin |
| Calcitonin | causes a decrease of calcium in the blood |
| PTH | causes a increase of calcium in the blood |
| Aldosterone | has its effect on the kidney cells |
| insulin | is made by beta cells in the pancreas, opposite effect of glucagon , decreases the blood glucose level |
| ovary | secretes estrogen |
| testosterone | secreted by intersticial cells, masculinizing hormone |
| Thymus | produces thymosin |
