| Question | Answer |
|---|---|
| any organ that produces a secretion | Gland |
| secrete substances into a duct | exocrine gland |
| secrete hormones directly into the blood stream or surrounding tissues | endocrine gland |
| chemical messenger that causes changes in a target cell with specific binding sites | hormone |
| lipid hormones that diffuse through the cell membrane and bind with receptors on the DNA which alters gene expression | steroid hormones |
| Peptide (Non-steroid) Hormones - protein hormones that bind to receptors on the outside of the cell membrane | peptide hormones |
| Nervous system transmits message to "middle man" gland & tropic hormone before final endocrine gland secretes desired hormone to target cells | hormonal control |
| A gland detects differences in chemicals in the body's internal environment and secretes hormones to bring conditions back to normal | humoral control |
| Nervous system sends message to one endocrine gland which secretes hormone to target cells | neural control |
| base of the brain in the sella turcica | pituitary gland location |
| the “Master” gland b/c it produces hormones that target hormone release from other endocrine glands | pituitary gland function |
| in the neck located below the larynx (Adam’s Apple) and over portions of the trachea | thyroid gland location |
| produces hormones that control the body’s metabolism | thyroid gland function |
| around the posterior thyroid gland | parathyroid gland location |
| produces hormones that increase blood calcium levels | parathyroid gland function |
| back of diencephalons | pineal gland location |
| regulates the body’s sleep/wake cycle & onset of puberty | pineal gland function |
| Posterior to the stomach along the abdominal wall | pancreas location |
| produces hormones that regulate blood glucose levels | pancreas function |
| top of kidneys | adrenal gland location |
| “Fright, fight, or flight” response | adrenal medulla function |
| middle of adrenal glands | adrenal medulla location |
| regulates that body’s mineral storage and water balance | adrenal cortex function |
| outer portion of adrenal glands | adrenal cortex location |
| in the mediastinum posterior to the sternum | thymus gland location |
| produces hormones that stimulate white blood cell development | thymus gland function |
| pelvic cavity | gonad location |
| produce hormones that influence primary and secondary sex characteristics | gonad function |
