What is the relationship between calcium and PTH? 

a. When extracellular Ca2+ is decreased àCa2+ binding to the receptor àinhibits PTH secretion

b. When extracellular Ca2+ concentration is increased à Ca2+ binds to the receptor à activates phospholipase C àinhibits PTH secretion

c. When extracellular Ca2+ is decreased à Ca2+ doesn’t binds to the receptor àstimulates PTH secretion

d. When extracellular Ca2+ concentration is increased à Ca2+ binds to the receptor à activates phospholipase C àstimulates PTH secretion.
