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.
Increased PTH causes the bones to release their calcium into the blood. When the calcium in our blood goes too high, normal parathyroid glands STOP making PTH--they shut down. Calcium is the most important element for the nervous system, the muscular system, and the skeletal system.lthough the parathyroid glands are located next to (and sometimes inside) the thyroid gland, they have no related function. The thyroid gland regulates the bodys metabolism and has no effect on calcium levels while parathyroid glands regulate calcium levels and have no effect on metabolism.
