Inhibition of PTH release from parathyroid chief cells
Option 1: Elevated blood calcium levels stimulate PTH release from parathyroid chief cells.
Option 2: Calcitonin promotes the release of PTH from parathyroid glands.
Option 3: Low blood phosphate levels inhibit PTH secretion.
Option 4: Vitamin D deficiency has no impact on parathyroid hormone release.
