The parathyroid artery is the single individual artery that provides oxygenated blood supply to the parathyroid glands. [1] While studies have concluded that most subjects' parathyroid glands are supplied by the thyroid arteries, up to 45% have been determined to have a "distinct anastomosing branch between the inferior and the superior thyroid ...
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.
The parathyroid gland produces and secretes parathyroid hormone in response to low blood calcium, which plays a key role in regulating the amount of calcium in the blood and within the bones. Parathyroid glands share a similar blood supply, venous drainage, and lymphatic drainage to the thyroid glands.
The particular problem or disease process will determine how many of the parathyroid glands are removed. Some parathyroid tissue must be left in place to help prevent hypoparathyroidism. Recovery after the operation tends to be swift. The PTH level is back to normal within 10–15 minutes, and can be confirmed by intraoperative rapid assessment ...

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.
Secondary hyperparathyroidism typically occurs due to vitamin D deficiency, chronic kidney disease, or other causes of low blood calcium. [1] The diagnosis of primary hyperparathyroidism is made by finding elevated calcium and PTH in the blood. [2] Primary hyperparathyroidism may only be cured by removing the adenoma or overactive parathyroid ...
[10] [11] The parathyroid gland is located beside the thyroid gland in the neck, below and in front of the larynx and above the trachea. It is composed of four glands in total that monitor blood calcium levels via the calcium sensing receptors, a g-coupled protein receptor. [12] The parathyroid glands main role is calcium homeostasis.
