Endocrine
| Question | Answer |
|---|---|
| Pituitary | master gland- small endocrine gland located at the base of the brain |
| Anterior pituitary | a gland that stimulates hormones, secretes growth hormone, LH, FSH, TSH, ACTH and prolactin |
| posterior pituitary | a gland that secretes two hormones: vasopressin (ADH) and oxytocin |
| Hypopituitarism | pituitary deficiency |
| Acromegaly | rare hormonal disorder that results from the overproduction of growth hormone (GH) |
| Hypothyroidism | is the result of the thyroid gland not being able to produce thyroid hormone |
| Hyperthyroidism | is the result of increased production of thyroid hormone |
| Crentinism | hypothyroidism in children |
| Myxedema | hypothyroidism in adults |
| Graves Disease | autoimmune disorder that causes hyperthyroidism |
| Plummers Disease | a thyroid disorder characterized by the development of multiple benign thyroid nodules that become overactive- leading to hyperthyroidism |
| goiter | an abnormal enlargement of the thyroid gland |
| LH | Luteinizing hormone, induces ovulation used to treat infertility: stimulate ovulation. (LH itself is not available) |
| FSH | Follicle stimulating hormone, stimulates follicle growth used to treat infertility |
| TSH | Thyroid stimulating hormone |
| ACTH | adrenocorticotropic hormone |
| hGH | human growth hormone treat children who lack development of muscles, illicitly used by body builders and weightlifters to develop muscles. |
| GnRH | Gonadotropin-releasing hormone (pharmaceutical) used to treat infertility, prostate cancer, and endometriosis |
| hCG | human chorionic gonadotropin is almost identical in structure to LH and can be used in its place. |
| hMG | human menopausal gonadotropin contains FSH and LH and is available as menotropin (Pergonal): used to treat infertility |
| (HRT) Hormone Replacement Therapy | conjugated estrogens (Premarin) |
| (HRT) Hormone Replacement Therapy | Medroxyprogesterone (Provera) |
| Thyroid drugs | levothyroxine sodium (T4) (Synthroid) liothyronine sodium T3 (Cytomel) propylthiouracil (PTU) methimazole (Tapazole) Sodium iodine / Iodine-131 [131I] (Draximage) |
| menotropin (Pergonal) | FSH and LH combined |
| leuprolide (Lupron, Eligardm Viadur) | GnRH |
| bromocriptine (Parlodel) | the only one not considered a hormone, it is an ergot derivative that inhibits pituitary function. Used to treat prolactin-secreting adenomas (hyperprolactinemia), acromegaly, and parkinson's disease |
| oxytocin (Pitocin) | the hormone oxytocin, administered as an injection or intranasally. Used to induce labor, control postpartum hemorrhage, and induce postpartum lactation. |
| desmopressin (DDAVP) and lypressin (Diapid) | vasopressin (antidiuretic hormone [ADH]). It is used for the long-term treatment of pituitary diabetes insipidus and to treat certain clotting disorders |
| The pituitary has two Lobes | anterior lobe, posterior lobe |
| The hypothalamus releases specific hormone-releasing substances | PIH, CRH, GHIH, TRH, GnRH, GGHRH |
| In response to those substances the pituitary releases specific hormones | From Anterior Lobe: Growth hormone, ACTH, TSH, FSH, LH, and Prolactin From Posterior Lobe: Oxytocin, ADH |
