Twin, small pairs of endocrine glands located adjacent to the thyroid gland; they secrete parathyroid hormone (PTH), which is essential for the regulation of calcium and phosphorus balance in the body.

Two pairs of endocrine glands located in the neck at the back of the thyroid gland. The parathyroid glands produce parathyroid hormone, which increases blood calcium levels by causing bones to release calcium into the blood, the kidneys to conserve calcium, and the intestines to increase calcium absorption from food. When blood calcium levels are high, the parathyroid glands reduce their production of parathyroid hormone, essentially reversing the process.

Any of four small kidney-shaped glands that lie in pairs near the lateral lobes of the thyroid gland and secrete a hormone necessary for calcium and potassium metabolism.

Glands producing parathyroid hormone which regulates calcium metabolism.

glands located on the posterior surfaces of the thyroid gland that produce parathyroid hormone.

small glands located on the posterior portion of the thyroid gland; produces parathyroid hormone used in controlling calcium levels in the blood

par-ah-THY-roid GLANZ Four small groups of cells behind the thyroid gland that regulate calcium level in blood and tissue fluid, by secreting parathyroid hormone. 663

(pair-a-THIGH-roid) Four pea-sized glands found on the thyroid. The parathyroid hormone produced by these glands increases the calcium level in the blood.

Four glands located on the back of the thyroid that produce parathyroid hormone.

Small glands located in the neck that produce a hormone which regulates calcium and phosphorus levels in the blood.

Four small glands located in the neck, near the thyroid gland. They produce parathormone which controls calcium metabolism. More about this. Production of too much parathyroid hormone causes primary hyperparathyroidism and osteoporosis More about this

Glands located behind the thyroid gland in the neck. The parathyroid glands secrete a hormone called parathormone (PTH) that is critical to calcium and phosphorus metabolism.

glands in the neck near the thyroid gland that help to control the body's calcium levels. Most people have four separate parathyroid glands.

Secrete a hormone that maintains the calcium level in the blood. Pineal body Involved with daily biological cycles.

Typically four small raisin-sized glands in the neck primarily involved in the regulation of calcium and phosphorus levels in the body.

Two pair of small glands situated next to or in the thyroid gland that are involved in the metabolism of calcium and phosphorus.

Endocrine glands adjacent to the thyroid gland in the neck, whose hormones regulate calcium metabolism, thus maintaining the normal excitability of the nervous system. Parathyroid inadequacy leads to tetany. See also endocrine system.
