Document Summary
S/n: this was not covered in lecture, but was an assigned reading! Secretes 75-80% epinephrine with remainder of secretion being norepinephrine. Epinephrine release triggered by activation of sns. Aldosterone makes up 95% of this class. Promotes na+ and water conservation and k+ excretion by renal tubules, regulating plasma volume. Corticosterone is another type of steroid secreted. The body for long-term stress and influence cell metabolism. Raise blood glucose levels via suppressing insulin secretion and promoting gluconeogenesis (this lowers glucose use by tissues, and promotes storage of glycogen in liver) Enhances protein breakdown for glucose conversion protein depletion results. Raises vascular smooth muscle sensitivity to norep. And angiotensin ii actions (modifies smooth muscle tone) Increases breakdown of bony matrix bone-demineralization. Stabilizes mast cells, inhibiting release of inflam. Corticotropin releasing factor (crf) is secreted by hypothalamus crf goes to pituitary, causes release of adrenocorticotropic hormone (acth) acth goes to adrenal cortex and stimulates release of glucocorticoids.
