About the parathyroid gland:
Abnormal function of the parathyroid glands may cause serious
disorders involving the renal, skeletal, and digestive systems.
Parathyroid glands, part of the body’s endocrine system, are four
small glands located behind the thyroid; these glands are about the
size and shape of a grain of rice. The purpose of the parathyroid
glands is to regulate the calcium level in our bodies within a very
narrow range so that the nervous and muscular systems can function
properly.
Problems with the parathyroid gland are usually not caused by
cancer, but rather by overgrowth and overactivity, requiring
surgical removal of abnormal gland or glands. Even though surgery
results in the loss of some parathyroid tissue, the body is typically
capable of maintaining calcium blood levels with only a small
portion of the this tissue remaining.
Although they are neighbors and both part of the endocrine system,
the thyroid and parathyroid glands are otherwise unrelated.
