HORMONES Flashcards
Target organ for Cortisol/Glucocoricoid from Adrenal CORTEX?
*what property in large amounts?
Stomach
Influences metabolism of food
*Anti-inflammatory in large amounts
Target organ for Aldosterone?
Kidneys
Increases reabsorption of sodium and excretion of potassium (regulates electrolytes)
What two important hormones come from the adrenal Medulla? Target organs?
Epinephrine - HR and force of contraction, vasodilation of mm
Norepinephrine - Vasoconstriction (viscera, skin, mm)
Cardiovascular/metabolic systems, influence nerve signals
Sympathetic impulses come from the _____ in stressful situations to release norep/epineph
hypothalamus
The x is an almond-sized structure on the floor of the brain. It’s a control center for hormones that influence our hunger, thirst, temperature, sleep cycles
hypothalamus
Target organ for Glucagon, released by?
Released by Pancreas
Target is Liver
Role is to increase blood glucose via glycogenesis
What hormone DECREASES blood glucose?
Insulin
What is role of parahomrone from parathyroids? Diseases can cause?
Increases BLOOD calcium
target organs: bones, kidneys, intestines
disease can cause brittle bones, kidney stones, fatigue
Gigantism, abnormal lactation, come from hyperactivity of what brain organ?
(Dwarfism, delayed growth/delayed puberty is due to hypo-activity)
Pituitary
Hyperglycemia, purple abdominal striae, truncal obesity, hump @ base of neck, weakness, acne, HTn, depression, poor concentration, memory loss
what syndrome?
Cushings (adrenals produce excessive cortisol)
Thyroid role in body?
STORE calcium and remove from blood (opposite of parathyroid), and cellular metabolism
The target of the hypothalamus is what organ?
Pituitary - tells it what to release via feedback loops in CNS
Antidiuretic hormone does what? is stimulated by?
Increases water retention and blood pressure
is stimulated by decreased water content in the body
regulated by pituitary
Disease with hypofunction of adrenals? Decreased ? and ? and main impact
Addisons
decreased cortisol and adosterone
main impact is fluid/electrolyte imbalances - result in LOW bp, anorexia, results in death if untreated
Ortho hypo is common secondary to long term ____ therapy
Cortisol
