| Question | Answer |
|---|---|
| Hypothalamus | The boss-controls the pituitary gland |
| Pituitary location | at the base of the brain just beneath the hypothalamus |
| Anterior pituitary Hormones | growth hormone, Prolactin,Thyrotropin (TSH),Adereno Corticotropic hormone (ACTH),LH,FSH |
| Posterior Pituitary Hormones | ADH,Oxytocin |
| thyroids Hormones | Thyroxine (T4), triiodothyrinine (T3) and calcitonin |
| Parathyroids hormone | secretion stimulated by hypocalcemia=increases reabsorption of calcium |
| Pineals hormone | melatonin |
| Thymus hormone | Thymosin,thymic humoral factor, thymic factor,thymopeitin (helps produce and distribute T cells to other lymphoid organs) |
| Pancreas hormones | Insulin, glucagon |
| Adrenal hormones | Cortisol,Aldosterone,Epinephrine, nor epi |
| Ovaries | Estrogen, progesterone |
| Testes | Testosterone |
| The 3 types of Hormones | Amines,proteins, Steroids |
| 5 functions of hormones | Growth,use food to produce energy,resistance to stress, ph of body fluids and balance of it, reproduction |
| ADH function | increases re-absorption of Na+ which increases volume thus increasing BP |
| Oxytocin function | Stimulates contraction of the uterus |
| Growth Hormone function | increases growth during childhood, and in adults stimulates the release of fat from adipose when hypoglycemic |
| Thyrotropin (TSH) | Stimulates the thyroid which releases T3 and T4 |
| Adrenocorticotropic (ACTH) | Stimulates the Adrenal Cortex to release cortisol and or aldosterone |
| Prolactin | increases milk production |
| Follicle Stimulating Hormone (FSH) | Regulated by (GnRH)-Stimulates Gonads-growth of ovarian follicles, estrogen secretion and sperm production |
| Lutenizing Hormone (LH) | Regulated by (GnRH)-responsible for ovulation, secretes progesterone and testosterone |
| Diabetes Insipidus | Hyposecretion of ADH-increased urination and thirst |
| Pituitary Dwarfism | Hyposecretion of GH |
| Giantism | hypersecretion of GH |
| Acromegaly | Hypersecretion of GH due to tumor |
| Goiter | Decreased T3 n T4, dietary deficiency of iodine-thyroid cells inlarge |
| Cretinism | Hyposecretion of T3 and T4 in newborns |
| Myxedema | Hyposecretion of T3/T4 in adults=decreased metabolic rate,S/S thickened dry yellow skin feels like dough, nonpitting edema,resp acidosis |
| Graves Disease | Hypersecretion of T3/T4=antibodies bind to TSH receptors=stimulate excess hormone=increasesd metabolic rate (SNS) rymptoms |
| Thyroid Storm | An acute rise in thyroid hormones=increase SNS activity-Tx Antithyroid meds (sodium iodine) |
| Pheochromocytoma | Tumor on the adrenal medulla that produces catecholamines |
| Addisons Disease | hyposecretion of Cortisol and Aldosterone S/S-dehydration,hyperpigmentation of skin n mucosa |
| Cushings Syndrome | hypersecretion of cortisol or too much steroids. s/s- fat deposits in the trunk of the body, buffalo hump, skin becomes thin n fragile |
| hormones produced by the islets of langerhans | insulin,glucagon,somatostatin |
| Estrogen | Promotes maturation of ovum |
| Progesterone | Promotes storage of glycogen and increase growth of blood vessels in endometrium |
| Testosterone | Promotes maturation of sperm |
| Inhibin | Secreted due to increased testosterone=decreases secretions of FSH by anterior pituitary, maintains constant rate of sperm |
