Protein derived hormones
|
synthesized, stored and released into the bloodstream in response to a stimulus
|
|
steroid hormones
|
synthesized in the adrenal cortex and gonads from cholesterol, are released as they are synthesized
|
|
Glucocorticoids
|
cortisol
influence carb storage, has anti inflam effects, and increases protein catabolism |
|
mineralocorticoids
|
aldosterone
regulates electolyte balance by promoting Na retention and K loss |
|
Thyroid Hormones
|
T3 and T4
regulates the metabolic rate of the body and greatly influence growth and development |
|
Parathyroid Hormone
|
PTH regulates calcium and phosphate metabolism
|
|
Pancreatic Hormones
|
Insulin and Glucagon
regulate the metabolism of glucose, lipids, and proteins |
|
Corticotropin releasing hormone or factor
|
causes the release of corticotropin (ACTH) in response to stress and threating stimuli
effects corticosteroids |
|
Thyroid releasing hormone
|
causes the release of TSH in response to stress, such as extreme cold
|
|
Anterior pituitary
|
synthesizes and secretes hormones
|
|
Posterior Pituitary
|
STores and releases hormones
|
|
Growth hormone releasing hormone
|
releases growth hormone
somatotropin |
|
growth hormone releasing inhibiting factor
|
Somatostaian
inhibits release of GH |
|
Gondadotropin-releasing hormone
|
affects FSH and LH
|
|
Posterior pituitary hormones
|
ADH
Oxytocin |
|
GH or somatotropin
|
Stimulates growth of body tissues. it regulates cell division and protein synthesis required for normal and promotes an increase in muscle cells and lengthening of bone
|
|
Which anterior pituitary hormones act directly on the target tissues
|
GH and prolactin
|
|
ADH or vasopressin
|
functions to regulate water balance by make renal tube more permeable to water
this raises blood volume and arterial blood pressure |
|
oxytocin
|
function in child birth and causes milk to come to the nipples
|
|
Leuprolide (Lupron) is use for what
|
Advanced prostatic cancer
Endometreosis uterine fibroid tumors |
|
Lupron AE
|
testosterone or estorgen deficiency like effects
increased bone pain difficulty urinating could agrivate deppresion |
|
Octreotide (sandostatin) indications
|
Acromegaly
AIDS diarrhea |
|
How do you give lupron
|
not orally b/c it is destroyed in the GI tract
|
|
Indications for Somatropin
|
children who's growth is impaired by a deficiency of endogenous hormones, chronic renal failure, turner's syndrome
only give it IM |
|
When is somatropin useless
|
when the epiphyses of the long bone are closed
|
|
Indications for desmopressin (DDAVP)
|
diabetes insipidus, bedwetting, and hemostasis of bleeding (hemoplilia)
|
|
Indications for VAsopressin
|
bleeding esophageal varices caused by longterm portal hypertension
|
|
Therapeutic effects of ADH drugs
|
decreased urine output
increased sp gravity decreased dehydration decreased thirst |
|
AE of somatotropin
|
mild edema, headache, muscle pain, weakness, and hyperglycemia
|
|
AE of DDVAP
|
headache, nasal congestion, nausea, and increased blood pressure. Serious water retention and hyponatreimia
|
|
AE of Vassopressin
|
water intox
chest pain MI inc blood pressure abdominal cramps |
|
AE of octreotide (sandostation)
|
dysrythmias, bradycarida, diarrhea, headache, hypergly, and gall stones
|
|
drugs that inc effect of vasopressin
|
general anestetics
|
|
drugs that dec effect vasopressin
|
lithium
|
|
drugs that increase effect of oxytocin
|
estrogens and vasoconstrictors (epi and norepi)
|
|
When does corticosteroid negative feedback not work?
|
during stress response b/c stress activates the SNS to produce more epi and norepi and the adrenal gland produces 10x the normal amount of cortisol
|
|
Addison's disease
|
primary adrenocortical insufficiency
destruction of the adrenal cortex TB, cancer, autoimmune disorders, prolonged steroid use; inadequate production of cortisol and alsosterone |
|
secondary adrenocortical insuficiency
|
inadequate gluccocorticoids but mineralcorticoid ok
|
|
what happens when the adrenal cortex is over functioning
|
cushing disease
|
