A femoral hernia occurs when the intestine enters the canal carrying the femoral artery into the upper thigh. Femoral hernias are most common in women, especially those who are pregnant or obese. In an umbilical hernia, part of the small intestine passes through the abdominal wall near the navel.
Parathyroid hormone is the most important endocrine regulator of calcium and phosphorus concentration in extracellular fluid. This hormone is secreted from cells of the parathyroid glands and finds its major target cells in bone and kidney.
Your parathyroid glands, four very small glands located near or at the back of the thyroid gland, produce parathyroid hormone (PTH). This hormone helps control the amount of calcium and phosphorus in your blood. A parathyroid adenoma is a benign tumor on one of these glands.
