Endocrine Notes

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
