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.
How parathyroid hormone works. Like in the thyroid, the parathyroids have receptors (in this case calcium receptors) that detect the level of calcium in the body. Parathyroid hormone (PTH) is released when these calcium receptors (CaR) on the surface of the parathyroid glands detect low blood calcium levels.ow parathyroid hormone works.
