The parathyroid glands are variable in number: three or more small glands, [5] and can usually be located on the posterior surface of the thyroid gland. [5] Occasionally, some individuals may have six, eight, or even more parathyroid glands. [3] Rarely, the parathyroid glands may be within the thyroid gland itself, the chest, or even the thymus ...

The four parathyroid glands are embedded in the thyroid gland. The chief cells of the parathyroid glands sense the amount of calcium in the blood, and release the calcium-increasing hormone parathyroid hormone (PTH) accordingly to correct or maintain normal blood calcium levels. [8]
A human being usually has four parathyroid glands located on the posterior surface of the thyroid in the neck. In order to maintain calcium metabolism , the parathyroid glands secrete parathyroid hormone (PTH) which stimulates the bones to release calcium and the kidneys to reabsorb it from the urine into the blood, thereby increasing its serum ...
The thyroid gland is located in the front of the neck, in front of the thyroid cartilage, and is shaped like a butterfly, with two wings connected by a central isthmus. Thyroid tissue consists of follicles with a stored protein called colloid, containing[thyroglobulin], a precursor to other thyroid hormones, which are manufactured within the ...
One of the most important functions of the hypothalamus—it is located in the brain adjacent to the pituitary gland—is to link the endocrine system to the nervous system via the pituitary gland.) Other organs, such as the kidneys, also have roles within the endocrine system by secreting certain hormones.
These tests are ordered by an endocrinologist or a surgeon that specializes in parathyroid surgery. Often, these "localizing" tests used to "find" the bad parathyroid gland are not successful in locating which parathyroid gland has become a tumor. This often causes confusion for the patient and doctor, since the tumor was not located.
Parathyroidectomy is the surgical removal of one or more of the (usually) four parathyroid glands.This procedure is used to remove an adenoma or hyperplasia of these glands when they are producing excessive parathyroid hormone (PTH): hyperparathyroidism.
