Question Magnesium and Parathyroid Hormone!

First aid really confused me. Low Mg would decrease PTH secretion.
Then errata corrected it and says low Mg will increase PTH.

Can someone explain this to me? Really confused.

all the cells in the body uses calcium influx to secrete the stored material in the cells except the cells that regulate the Calcium "parathyroid cells" which uses Mg++ influx to secrete the stored PTH so the low Mg++ --> low PTH. i hope it is clear now.

A slightly decreased Mg will tend to increase PTH secretion. Whereas a severely decreased Mg will decrease PTH secretion.
