Parathyroid gland
The parathyroid glands are small, pea-sized organs located in the neck behind the thyroid gland. There are typically four parathyroid glands in the human body, although some people may have more. Despite their small size, these glands play a critical role in regulating the body's calcium levels, which is essential for maintaining healthy bones and teeth, as well as proper nerve and muscle function.
The primary job of the parathyroid glands is to produce parathyroid hormone (PTH). PTH helps control the amount of calcium in the blood and bones by signalling the bones to release calcium, the kidneys to reduce calcium loss through urine, and the intestines to absorb more calcium from food. Because of their significant role in calcium balance, any issues with the parathyroid glands, such as hyperactivity or underactivity, can lead to health problems, including bone disorders and muscle weakness.
These glands are often overlooked due to their small size and location but are vital for maintaining the body's calcium levels and, by extension, supporting overall health and well-being.
