ENDO: Overview 2
Endocrine system overview part 2.
| Question | Answer |
|---|---|
| thyroid gland function | regulates metabolism and calcium level |
| adrenal gland function | -Controls electrolyte levels -Responds to stress: Alters metabolism and interacts with sympathetic nervous system |
| gonads | ovaries and testes |
| mammary glands | Specialized organs in mammals that produce milk to nourish the young |
| pituitary gland | The endocrine system's "master" gland. Under the influence of the hypothalamus, the pituitary controls other endocrine glands. |
| neurohormones | produced and released by neurons in the brain, rather than by the endocrine glands, and delivered to organs and tissues through the bloodstream |
| hypothalamus | A neural structure lying below the thalamus; it directs several maintenance activities (eating, drinking, body temperature), helps govern the endocrine system via the pituitary gland, and is linked to emotion and reward. |
| pineal gland function | controls our daily rhythms- sleep wake cycle |
| melatonin | A hormone manufactured by the pineal gland that produces sleepiness. |
| parathyroid | controls the calcium levels in your body, and normal the bone growth |
| parathyroid hormone (PTH) | increases blood calcium levels; stimulates kidneys & intestines to absorb more calcium; breaks down bones |
| thymus | An immune organ that is the site of T cell maturation and is larger in children and adolescents. |
| thymosin | secretion of thymus that augments maturation of T-lymphocytes |
| adrenal cortex | the outer portion of the adrenal glands |
| adrenal medulla | The middle portion of the adrenal glands. |
| Thyroxine (T4) and Triiodothyronine (T3) | Two primary thyroid hormones that regulate the rate of metabolism |
| Mineralocorticoids | Secreted by adrenal cortex (sodium & water) |
| Glucocorticoids | Secreted by adrenal cortex (glucose) |
| epinephrine and norepinephrine | secreted by the adrenal medulla |
