parathyroid glands
parathyroid glands , four small endocrine bodies, located behind the thyroid gland, that govern calcium and phosphorus metabolism. These four masses of tissue (each about the size of a pea) are difficult to distinguish from the thyroid and are often embedded in it. Consequently, before their... Read more |

Hypoparathyroidism
Hypoparathyroidism Definition Hypoparathyroidism is the result of a decrease in production of parathyroid hormones by the parathyroid glands located behind the thyroid glands in the neck. The result is a low level of calcium in the blood. Description Parathyroid glands consist of four pea-shaped... Read more |

tetany
tetany , condition of mineral imbalance in the body that results in severe muscle spasms. Tetany occurs when the concentration of calcium ions (Ca ++ ) in extracellular fluids such as plasma falls below normal. The nervous system becomes increasingly excitable, and nerves discharge spontaneously,... Read more |

Hypercalcemia
Hypercalcemia Definition Hypercalcemia is an abnormally high level of calcium in the blood, usually more than 10.5 milligrams per deciliter of blood. Description Calcium plays an important role in the development and maintenance of bones in the body. It is also needed in tooth formation and is... Read more |

Hyperparathyroidism
Hyperparathyroidism Definition Hyperparathyroidism is the overproduction by the parathyroid glands of a hormone called parathyroid hormone (parathormone). Parathyroid glands are four pea-sized glands located just behind the thyroid gland in the front of the neck. Parathyroid hormone (parathormone)... Read more |
