3 classes of steroid hormones
glucocorticoids
mineralocorticoids
gonadocorticoids
gonadocorticoids =
androgens = puberty
mineralocorticoids =
aldosterone = regulation of plasma volume with sodium reabsorption and potassium excretion = RAAS
= excessive ADH = HTN and hypokalemia
tumors
glucocorticoids =
30 = cortisol, cortisone, etc = effect nearly every cell
functions of glucocorticoids
oIncrease the level of blood glucose (hyperglycemic effect) by inhibiting insulin secretion and promoting gluconeogenesis, the synthesis of carbohydrates from lipid and protein sources
oIncrease the breakdown of proteins and lipids and promote their utilization as energy sources
oSuppress the inflammatory and immune responses (see Chapters 33 and 34)
oIncrease the sensitivity of vascular smooth muscle to norepinephrine and angiotensin II
oIncrease the breakdown of bony matrix, resulting in bone demineralization
oPromote bronchodilation by making bronchial smooth muscle more responsive to sympathetic nervous system activation.
