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.
Parathyroid hormone influences the levels of both calcium and phosphorus in the body. A portion of PTH is split into 3 fragments in the parathyroid gland before systemic release.The 3 fragments are an amino or N-terminal fragment, a midregion fragment, and a carboxy or C-terminal fragment.The active intact PTH and the amino terminal fragment are physiologically active in the body. portion of PTH is split into 3 fragments in the parathyroid gland before systemic release.
