Parathyroid Accessory Glands

Accessory parathyroid glands (lat. Glandulae parathyroideae accessoriae) are additional parathyroid glands that are located on the posterior surface of the thyroid gland. They play an important role in regulating calcium and phosphorus metabolism in the body.

The main function of the parathyroid glands is to regulate calcium levels in the blood. When there is a lack of calcium in the body, the parathyroid gland secretes parathyroid hormone (PTH), which stimulates the absorption of calcium from the intestines and its deposition in the bones. When there is excess calcium in the blood, the parathyroid glands secrete calcitonin, which helps remove calcium from the body.

However, some people may have additional parathyroid glands on the back of the thyroid gland, called accessory parathyroid glands or accessory parathyroid glands. These glands can be either functional or non-functional.

Functional accessory parathyroid glands can produce parathyroid hormones, which leads to increased calcium levels in the blood and the development of hypercalcemia. In this case, treatment may be required, which may include lowering calcium levels in the blood by taking calcium supplements or lowering parathyroid hormone levels by having surgery on the gland.

Nonfunctional accessory parathyroid glands do not produce parathyroid hormones and do not affect the level of calcium in the blood. They can be detected during an ultrasound examination of the thyroid gland or when examining a patient with suspected hyperparathyroidism.

In general, the accessory parathyroid glands play an important role in maintaining normal calcium levels in the body and can lead to the development of hypercalcemia during functional activity. However, if they are not functional, they do not pose a health hazard and do not require treatment.



The accessory parathyroid glands are small clusters of parathyroid glands that are located in the neck and throat. They play an important role in regulating calcium and phosphorus levels in the body.

The parathyroid glands are part of the endocrine system and produce parathyroid hormone, which regulates calcium levels in the blood. When there is a lack of calcium in the body, the parathyroid gland begins to produce more of a hormone that helps the body absorb calcium from food.

However, in some cases, people may experience additional accumulations of parathyroid glands. These glands are called parathyroid accessory glands. They can be found on the neck or throat and usually do not cause any symptoms.

If the accessory parathyroid glands begin to work incorrectly, this can lead to various diseases, such as osteoporosis, hypertension and others. Therefore, if you discover that you have additional parathyroid glands, it is recommended that you consult a doctor for advice.

In general, parathyroid glands are not a serious health problem, but they can cause some symptoms if they start to malfunction. Therefore, it is important to monitor your health and consult a doctor if necessary.
