Parathyroid hormone (in high concentrations in the blood) causes bone resorption, releasing calcium into the plasma.
Mild vitamin D insufficiency is associated with increased parathyroid hormone (PTH) production.
The parathyroid chief cells secrete parathyroid hormone (PTH) in response to a fall in the plasma ionized calcium level; the parafollicular cells of the thyroid gland secrete calcitonin in response to a rise in the plasma ionized calcium level.
This is accomplished via the Parathyroid hormone 1 receptor (PTH1) in the kidneys and bones, or via the Parathyroid hormone 2 receptor (PTH2) in the central nervous system and brain, as well as the bones and kidneys.
