Document Summary
Increases phosphate release from bone and decreases phosphate reabsorption in kidney. Darkness; secreted at night (sleep: parathyroid hormone (pth) Rankl on osteoblasts by increasing camp and decreases opg expression so that more osteoclasts are formed leading to reabsorption from bones. In kidney, pth increases reabsorption of calcium from filtrate and enhances calcium ions going into blood and prevents loss of urinary calcium and thus, increases ca2+ reabsorption from distal tubule. C cells (parafollicular cells) of the thyroid gland. Vasopressin binds to p. m. receptors o cells and triggers increase in ac and camp, which activates pka. This causes aquaporin-2 water pores to exocytose on the. Increases expression of ca2+ channels/ binding proteins/ transporters in kidney and intestine and also rankl and. Decrease na+ and h2o reabsorption, increase k+ reabsorption. Reduces blood glucose, promotes formation of glycogen, fat and protein. apical membrane of the collecting duct and enhances water permeability. Glut 4 transporters found in muscle and adipose tissues.
