SUMMARY
FUNCTION
1. Stimulates osteoclast activity ⟹ releases bone calcium stores.
2. Increases renal tubular calcium absorption + phosphate excretion.
3. Increases 1,25-dehydroxycholecalciferol (1,25-(OH)2D) production by increasing activity of kidney hydroxylase.
CONTROLLED BY NEGATIVE FEEDBACK
4. High serum calcium ⟹ decreased parathyroid PTH production.
