  2. Parathyroid hormone - Wikipedia

    en.wikipedia.org/wiki/Parathyroid_hormone

    PubMed search. [3] [4] Wikidata. View/Edit Human. View/Edit Mouse. Parathyroid hormone (PTH), also called parathormone or parathyrin, is a peptide hormone secreted by the parathyroid glands that regulates the serum calcium concentration through its effects on bone, kidney, and intestine. [5] PTH influences bone remodeling, which is an ongoing ...

  3. Parathyroid gland - Wikipedia

    en.wikipedia.org/wiki/Parathyroid_gland

    Parathyroid glands are small endocrine glands in the neck of humans and other tetrapods. Humans usually have four parathyroid glands, located on the back of the thyroid gland in variable locations. The parathyroid gland produces and secretes parathyroid hormone in response to low blood calcium, which plays a key role in regulating the amount of ...

  4. Hyperparathyroidism - Wikipedia

    en.wikipedia.org/wiki/Hyperparathyroidism

    Hyperparathyroidism is an increase in parathyroid hormone (PTH) levels in the blood. [1][4] This occurs from a disorder either within the parathyroid glands (primary hyperparathyroidism) or as response to external stimuli (secondary hyperparathyroidism). [1] Symptoms of hyperparathyroidism are caused by inappropriately normal or elevated blood ...

  5. Parathyroid disease - Wikipedia

    en.wikipedia.org/wiki/Parathyroid_disease

    The single major disease of parathyroid glands is overactivity of one or more of the parathyroid lobes, which make too much parathyroid hormone, causing a potentially serious calcium imbalance. This is called hyperparathyroidism; it leads to hypercalcemia, kidney stones, osteoporosis, and various other symptoms.

  6. Hypoparathyroidism - Wikipedia

    en.wikipedia.org/wiki/Hypoparathyroidism

    Hypoparathyroidism is decreased function of the parathyroid glands with underproduction of parathyroid hormone (PTH). This can lead to low levels of calcium in the blood, often causing cramping and twitching of muscles or tetany (involuntary muscle contraction), and several other symptoms. It is a very rare disease.

  7. Tertiary hyperparathyroidism - Wikipedia

    en.wikipedia.org/wiki/Tertiary_hyperparathyroidism

    Surgery, intravenous normal saline. Frequency. ~2 per 1,000. Tertiary hyperparathyroidism is a condition involving the overproduction of the hormone, parathyroid hormone, produced by the parathyroid glands. [1] The parathyroid glands are involved in monitoring and regulating blood calcium levels and respond by either producing or ceasing to ...

  8. Primary hyperparathyroidism - Wikipedia

    en.wikipedia.org/wiki/Primary_hyperparathyroidism

    Thyroid and parathyroid. Primary hyperparathyroidism (or PHPT) is a medical condition where the parathyroid gland (or a benign tumor within it) produce excess amounts of parathyroid hormone (PTH). The symptoms of the condition relate to the resulting elevated serum calcium (hypercalcemia), which can cause digestive symptoms, kidney stones ...

  9. Parathyroid chief cell - Wikipedia

    en.wikipedia.org/wiki/Parathyroid_chief_cell

    Parathyroid chief cells (also called parathyroid principal cells or simply parathyroid cells) are one of the two cell types of the parathyroid glands, along with oxyphil cells. [1] The chief cells are much more prevalent in the parathyroid gland than the oxyphil cells. It is perceived that oxyphil cells may be derived from chief cells at ...
