Parathyroid glands are small endocrine glands in the neck of humans and all tetrapods.[1]

Function[change | change source]

These glands produce parathyroid hormones (PTH). This has an important role in controlling the amount of calcium in blood and bones. Calcium is an important element in our body: it is the only element with its own control system (the parathyroid glands).

Structure[change | change source]

There are two pairs of parathyroid glands, just behind the thyroid glands. Each gland is about 6 mm long and 3–4 mm wide. Parathyroid glands get their blood supply from the inferior thyroid arteries.[2]
