A thick connective tissue capsule separates the glands from the thyroid tissue. Most people have four parathyroid glands, but occasionally there are more in tissues of the neck or chest. The function of one type of parathyroid cells, the oxyphil cells, is not clear. The primary functional cells of the parathyroid glands are the chief cells.

It highlights the effects of hypothyroidism and hyperthyroidism, including associated disorders like cretinism, myxedema, and Graves' disease. Furthermore, it covers the parathyroid glands and their secretion of PTH, which increases blood calcium.
