Summary Introduction
Introduction:
Parathyroid gland secretes the parathyroid hormone that is the regulator of calcium homeostasis of the blood. Parathyroid glands are small in sizes which are present on the posterior to the thyroid gland. Typically, there are four of them, but the number may vary from person to person.
