Question | Answer |
---|---|
hypothalamus secondary glands | posterior and anterior pituitary |
prolactin releasing hormone | anterior pituitary - prolactin |
prolactin | stimulates secretion of milk by mammary glands |
growth hormone-releasing gactor (GRF) | anterior piuitary - growth hormone |
growth hormone | promotes growth of body tiss |
S&S of Growth hormone imbalance | hypo-dwarfism hyper- giantism |
posterior pituitary | oxytocin & ADH (vasopressin) |
oxytocin | causes contraction of muscle of uterus; causes ejection of milk from mammary glands |
ADH (vasopresin) | promotes reabsorption of mater in kidney tubules; stimulates smooth muscle tissue of blood vessels to constrict |
Over and under production of ADH | hypo- diabetes insipidus hyper- syndrome of inappropiate ADH (SIADH) |
Hypothalamus -gonadotropin releasing hormone | follicle stimulating hormone (FSH) and Luteinizing hormone (LH) |
FSH & LH male gland hormone | testes/testosterone |
FSH & LH female gland hormone | ovary/estrogen |
FSH & LH Male Principle Function | stimulates growth of testes and penis; promtoes development of sperm cells; development of secondary sexual characteristics such as hair growth on body and face and deeping of voice; stimulates maturation of sperm cells |
FSH & LH Female Principle Function | stimulates growth of primary sexual organs and development of secondary sexual organs such as breasts, plus changes in pelvis to ovoid broader shape |
hypothalamus tertiary glands | testes, ovary, adrenal cortex, thyroid, parathyroid, adrenal medulla, pancreas |
hypothalamus corticotropin releasing hormone | adrenocorticotropic hormone adrenal cortex |
adrenal cortex | glucocorticoids |
glucocorticoids | aids in protecting body in stress situations |
Over and under production of Glucocorticoids | hypo- addison's hyper-cushing's |
Thyrotropin releasing hormone (TRH) | thyroid stimulations hormone (TSH) |
Thyroid | thyroid hormones 7 calcitonin |
Uncer and over production of Thyroid Hormones | hypothyroidism & hyperthyroidism |
Thyroid hormones Principle function | increase the rate of metabolism of most body cells |
Calcitonin Principle Function | hypo- too much Ca hyper- too little Ca |
Parathyroid | PTH |
PTH Principle function | Ca and Ph bone metabolism |
Over and under production of PTH | hypo- to little Ca hyper- too much CA |
Adrenal Medulla | epinephrine and norepinephrine |
epinephrine and norepinephrine Principle Function | increase heart rate and BP, activates SNS |
Over and under production of epinephrine and norepinephrine | hypo-severe hypotension, cardiovascular collapse hyper- hypertension |
Pancreas | glucagon and insulin |
Glucagon Principle Function | increase blood glucose levels |
Insulin Principle Function | decrease blood glucose levels |
Over and under production of Glucagon | hypo- hypoglycemia hyper- hyperglycemia |
Over and under prodcuction of Insulin | hypo- diabetes mellitus, kertoacidosis hyper- hypoglycemia, insulin shock |
