The endocrine glands are The parathyroid glands.
The parathyroid glands are classically four in number for the majority of patients. They secrete parathyroid hormone, a hormone needed for calcium metabolism. The overproduction of parathyroid hormone or parathyroid hormone, or on the contrary, the deficiency of parathyroid hormone (PTH), are two pathologies that can affect the parathyroid glands.
Parathyroid glands are original endocrine glands: they are devoid of pituitary control. It is the changes in blood calcium that regulate their secretion.
Parathyroid hormone secreted by parathyroids raises the level of calcium in the blood.
Parathyroid hormone plays a crucial role in the metabolism of calcium and vitamin D.
