Parathüroidnääred
Parathüroidnääred are small endocrine glands located in the neck, typically situated behind or attached to the thyroid gland. Humans usually have four parathyroid glands, two on each side, but variations in number and location can occur. These glands are crucial for regulating calcium and phosphate levels in the blood.
The primary hormone produced by the parathyroid glands is parathyroid hormone (PTH). PTH plays a vital role
Conversely, when blood calcium levels are sufficiently high, PTH secretion is suppressed, helping to prevent hypercalcemia.
