PET CAD (+ Thyroid)Progesterone EstrogenTestosteroneCortisolAldosteroneVitamin D
Endocrine
Secretion into blood
Exocrine
Secretion into not blood
Autocrine
Works on itself
Paracrine
Works on its neighbors
Merocrine
Exocytosis - cell is maintained
Apocrine
Apex of cell secreted
Holocrine
Whole cell secreted
Organs that do not require insulin for glucose
BRICKLEBrainRBCIntestinesCardiac, CorneaKidneyLiverExercising muscle
GnRH
Stimulates FSH and LH
GRH
Stimulates GH
CRH
Stimulates ACTH
TRH
Stimulates TSH
PRH
Stimulates Prolactin
Dopamine
Inhibits Prolactin
Somatostatin
Inhibits GHInhibits secretin, motilin, CCK
ADH
Conserves waterVasoconstrictsConcentrates urine
Oxytocin
Milk productionBirth
GH
IGF-1 release from liverGrowthSends somatomedin to growth platesGluconeogenesis by proteolysis
TSH
T3 and T4 release from thyroid
LH
Testosterone release from testesEstrogen and Progesterone from ovary
FSH
Sperm or egg growth
ACTH
Cortisol release from adrenal gland
MSH
Skin pigmentation
Stress Hormones
Immediate = Epinephrine20 minutes = Glucagon30 minutes = Insulin and ADH2-4 hrs = Cortisol24 hrs = GH
Diabetes Insipidus
Too little ADHUrinate a lot
Central DI
Brain not making ADH
Nephrogenic DI
Blocked ADH receptorCan be caused by Lithium or Demecocycline
Water deprivation test
Concentrate urine = PsychogenicFail to concentrate urine = DI
DDAVP
Concentrate urine = Central DIFail to concentrate urine = Nephrogenic DI
SIADH
Too much ADHExpanded plasma volumePee Na+
Difference between SIADH and DI
DI = dilute urineSIADH = concentrated urine
Psychogenic Polydipsia
Pathologic water drinkingLow plasma osmolarity
Aldosterone
Reabsorbs Na+Secretes H+ and K+
Neuroblastoma
Adrenal medulla tumor in kidsDancing eyes and feetSecretes catecholamines
Pheochromocytoma
Adrenal medulla tumor in adultsPressurePainPalpitationsPerspirationPallor
Zona Glomerulosa makes
Aldosterone
Zona Fasiculata makes
Cortisol
Zona Reticularis makes
Androgens
Conn’s Syndrome
High aldosterone d/t tumorCaptopril test makes it worse
ANP
Inhibits aldosteroneDilates renal artery (afferent arteriole)
